Installing MS2 on 99
2 Attachment(s)
msq is attached.
It connects, but is not happy yet. Brain built squirt running the gslender v2.2 found here: http://msextra.com/forums/viewtopic.php?f=91&t=43545"]link Here are some problems: - no TPS signal - coolant reading 180F after entering calibration values from here - strange humming sound coming from the intake when MS is on. - not sure if I am wiring in the AIT correctly (see next post with pic) Will be checking this thread intently over the next two hours, so I can hopefully make some progress today. Thank you! |

attached is the photo of where I plugged in the AIT sensor.
Some more info: - RPMs are not reading when I tried to crank. Reading zero. - MAP reads about 95 - I have not hooked up the wideband yet - I can hear the fuel pump running - MAT jumps from 0-60-0 in weird little pulses When i click 'Test Port' it initially says successful, then gives me an error message, then connects. See attached pic. |
Don't let my name or sig fool you- this is an install on a 1999.
|
My noobish guess is a firmware issue.
I am not able to write anything to the MS. It will not even burn a change to the fuel table. It lost the calibration settings for coolant and iat after restarting. Edit: it says 'not synced' lit up in red in the bottom right. |
Why would you think that? Fix your config error! You can't do anything until you do that! The flashing red tach that cycles between 0 and 65k rpm, the pulsing fuel pump, the config error pop window, and the red light that says config error are supposed to be clues that something is wrong. And the pop up window tells you how to go about fixing the problem.
Since Braineack was able to connect, it's probably a safe bet that your problem is related to your USB adapter (I assume you're running a serial -> usb) or improper project settings. What kind of cable are you using? Take a screen shot of your communications settings. There are a few threads on the msextra forums on this. Here are a couple of links http://www.msextra.com/forums/viewto...?f=101&t=31532 http://www.msextra.com/forums/viewto...?f=101&t=40590 http://www.msextra.com/forums/viewto...?f=131&t=43173 |
I misspoke and did not mean firmware. I meant what I have loaded in tunerstudio. The .ini stuff. Brain is going to send me the right stuff tonight, and will try ago in tomorrow.
The computer is back with the car at another house, can not do a screenshot now. I don't have a USB. I think it is just called a serial cable. The cable was working fine before the upgrade to ms2. |
I read through those threads Ben. Looks like it is possible it is my cable. Since it was working on the MS1 with no problems, maybe it can not handle the increased baud rate (I think that's what they call it).
Brain sent me a new project folder and .ini, and it is still acting the same. I attached a pic of the communications settings. This is after it tells me the connection is successful. Anything stupid that I am just not thinking of? Last time I had to deal with setting things up was a few years ago, and I struggled then. I can not upload the pic- but here is what it says: Comm Settings Port: COM1 Baud Rate: 115200 Successful!!! Then the message of death: turbo99final Controller Error: You have a configuration error! This means there are conflicting settings and the Controller does not know how to handle them. The Controller message below should provide some guidabce to the incorrect settings. Correct your settings then powercycle the Megasquire You do not need to reload the firmware to fix this problem. Controller message: Seral problem- framing error - possible cable, computer hardware or settings problem. |
that project folder i sent you, put that into your tunerstudio project folder. then go to file, open project, and select that one. then try to connect. if it doesn't work it's gotta be your version of TS or your serial cable.
|
I think I have the most recent version: 1.006.
And who the ---- are you, anyway? Who the ---- are they? Who the ---- am I to say? What the ---- is really going on? How did the ms2 get so fat? I am going to start shopping around for a new chord. |
Before you get a new cable, have you tried any of the comms troubleshooting from the manual? What about reloading the firmware and starting a new project? I would try that, and I'd try it with the most recent stable firmware.
serial troubleshooting http://www.msextra.com/doc/ms2extra/serial_setup.html firmware http://www.msextra.com/doc/ms2extra/....1_release.zip |
Thanks, I will read that.
I wanted to bring the car home tonight, so I put in the old computer and hooked everything back up. Won't start. I can smell raw fuel at the tailpipe. Don't know how timing could have changed, so that leaves me with spark. I thought we were done with the days of worrying about blown coil packs?!? ---- Maybe related: that humming sound I mentioned earlier is still there when keyed on. I can't locate the exact source, but it is strongest at the intake piping. It is not the maf. Maybe something wired with the supercharger. Idk. Frustrated at the moment. Have a truck I can drive, but I want to try to get this sorted out quickly. |
Just curious, but is this a DIYPNP?

ugh, had a long post written and the stupid blackberry playbook crashed the browser. Technology fails me today.
Brain, when I tried that, it would not connect at all. Kept giving the same error message indicating hardware or setting problem. I checked for updates of TS and I have the most recent. Have been using an old laptop with windows 2000 professional. COM troubleshooting scares me. I have a new laptop with windows 2007, but will need a usb. Ordered the cable mentioned in the first post here. Nervous about the no start on the stock* computer. On Saturday, I cranked to check for rpm in tunerstudio (none shown), and I am pretty sure I still had the maf connected. What did I fry? I doubt I will start on ms, when I can't now. I do not know if the humming sound is pre or post supercharger (forgot to pull off all of the intake pipes). It is noticeably loud. The super has no electronics. I have no idea. * 99 computer with VF Engineering chip |

Do not belive so. It was originally a ms1 that I have been using on my 94 for the past few years. Brain sprinkled some cat hairs on it, and it turned into the ms2.
Once you get this thing to connect and you get it running, I'm curious to see how this works out for you. I'm also interested in more details, but that's another time...no thread jack here. Good luck getting it sorted out! |
Morning bump for the working crew.
New cable arrives on Wednesday. Guesses as to what I need to fix to run stock computer? |

yeah I've never seen that error before. I had no issue loading the firmware and map and stiming the ECU. |

summary: -car ran flawless before failing at ms2 install, including a couple cranks -back on stock computer: cranks but no start. Raw fuel smell from tailpipe. -strange electrical humming sound from the intake piping (not the MAF) when key switched 'ON'. Humming present also with ms2 plugged in. Never noticed it before last weekend. Have tunerstudio installed in the newer laptop, and received the new chord. https://www.miataturbo.net/attachmen...ine=1328749714 Stupid question for brain: should I load the "CurrentTune" you sent to me in the project folder or should I try to load the msq contained on the MS? Stupid questions for everyone: There are two plugs in the air filter area. One is clearly going to the MAF. The other has two wires and is sticking out of the end of the filter. Do I plug the AIT sensor into the two wire? That is how I set it up last weekend (see third pic). What do I do with the MAF plug? Leave it unconnected to anything? https://www.miataturbo.net/attachmen...ine=1328749714 https://www.miataturbo.net/attachmen...ine=1328749714 https://www.miataturbo.net/attachmen...ine=1328749714 I appreciate any help! |

Do I leave these settings as is?
These do not look familiar from ms1, and it popped up by itself. Attachment 186033 |
Diving in again tomorrow morning.
Plans are to figure out where exactly the electric humming is coming from, as well as successfully connect to the ms2. Frustrated posts to follow. |

I assume your stock IAT sensor is stuck into a hole drilled in your filter. I'm pretty sure you will need to get a GM IAT sensor, and I'd weld a bung onto your pre throttle body plumbing and screw the sensor into it. Here is the sensor you need: http://www.diyautotune.com/catalog/g...tail-p-62.html As for a bung, don't spend $9 on one. If your plumbing is steel, just buy a 3/8" pipe coupling at the local hardware store, cut it in 1/2, drill a hole in your plumbing and weld it up. |
The humming sound is coming from your idle valve. This is perfectly normal.

Thanks reverant!
Thirdgen, I have the GM AIT sensor. Will wire it into the stock AIT sensor. What do I do with the plug for the MAF? My original cable was definitely one problem. The new one cleared up some issues, but it is still not able to get a TPS signal, and setting the coolant and AIT does not save. I gave up on the gslender firmware. Loaded up the regular firmware that Ben posted. Still having similar issues with the TPS and settings for coolant and AIT. I am wiring up the wideband and AIT now. May go ahead and swap the stock injectors for the 460s and see if I can get it started. Maybe I am getting ahead of myself since I still have software issues. I don't know what to do...:facepalm: |
Wideband is hooked up and working with the ms :)

I don't know what to do...:facepalm: Don't swap in the 460's, keep the stock injectors in. Make sure the required fuel is 13.2 and make sure you're getting spark. Are you running stock coils? |
Yes, running stock coils. Will set the required fuel to 13.2.
More progress: The AIT is reading accurate. I used the preprogrammed settings for the GM sensor. Previously I had been inputting Brain's from here: http://www.boostedmiata.com/gallery2...TS_3_1_0v1.pdf and tunerstudio was not happy. Guage read at zero and would sporatically jump and go back to zero. Coolant is not happy. Reads at 180....oh wait...I unplugged the sensor to get the coil pack loose before i loaded the firmware! Checking that now! |
So far the only things I can not get to work properly are TPS and coolant.

I'm not sure what's up with that photo...
Did you compare my .msq and iron out your issues? |
Been going through it line by line this morning. Already finding some significant changes. Thanks again.
Should be reporting back in a couple hours. |

Attached is the current msq I am using along with a datalog of two cranks.
TPS is still screwy, along with coolant, and still no RPMs (in either tunerstudio or the dash). I imagine the RPM issue is a main problem, as I have seen a million threads in the past with no rpm/no start. Found this thread on the TPS: LINK Brain, any chance this is related? I am getting the same 1023 whether throttle opened or closed, and TS reads 100%.

I'm guessing that the TPS is possibly bad but I'd just replaced a few months before I started this little project and it seemed to work ok.... I don't see anything saying what readings you should get roughly when calibrating except that the idle should definetly be lower that WOT. Is there any other setting that could be affecting the calibration of this thing? Its a 88 ford Ranger 2.3L with Megasquirt II V3.57.. Any help would be appreciated. Thanks
........ Ok figured this one out it was a ground missing. It gave me a 1023 reading when trying to calibrate the TPS in both idle and WOT. So it looked like a open circuit and I hadnt noticed that both the intake air temp and water temp were also both reading very high! So I went back and looked at the wiring diagram for the vehicle and found that the ground for the TPS followed along into the EGR valve and then went to a common ground before going off to the other sensors. Well since removing the EGR and a few other sensors there was no longer a path to recieve the ground... As soon as I fixed that well it all works great now! |

According to http://www.diyautotune.com/diypnp/ap...0-18bp-mt.html your ignition settings are mostly wrong.

edit:except for the Output Port settings. I left those blank, and did not copy thirdgen's bc I was scared to fool with it. |
If you're running the stock Mazda ignition (meaning you haven't installed coil-on-plug ignition or anything) then use DIY's igntion settings exactly.
Any luck with the TPS? You need to have that working because right now your MS is reading 100%. The default setting for "flooding clear mode" is 70% so if the MS sees a throttle position above that it will not inject any fuel. |
You did calibrate the TPS, right?
|
please don't arbitrarily change my settings, the basemap was setup exactly for YOUR ms. It shares little in common with a DIYPNP.
It actually appears as though I swapped the ckp/cmp inputs on the harness. |

Could not find anything for: - skip pules - box on left - spark A output pin - fixed advance - box on right - use prediction Great point on the flood clear. Tried to change it to 110% to take away authority, and it does not allow. Can not set the TPS at all. It reads 1023 no matter where the pedal is pressed. Attachment 186028 |
My bad, defer to Brain. I didn't realize this was the case.

Why not reload Brain's map and see what can be done with it? You have plenty of time before tomorrow & can still mail it out if need be.
Might as well learn by doing, then in the future you will have an idea of how everything works if something goes wrong instead of having to mail off your MS every time... |
there are some hardware issues. I proved myself incapable of soldering when I blew up a 14point7 build.

Brain swapped 3J and 3H, the two Cam inputs. He also checked the CLT and TPS, which both worked fine on the stim.
CLT and TPS are still not connecting properly. I directly connected red/blue on 2E from this wiring diagram to the Yellow 2E on the pinout below, and it is still not reading coolant temp. https://www.miataturbo.net/attachmen...ine=1330453175 Scott is thinking they share a ground and it could be faulty. Any idea where this ground is located? Any other ideas?? |
I should add, coolant temp read fine on the dash before attempting any of this.
|
Yeah, I'm a bit clueless on this. I did mistakenly have the cam/crank inputs crossed on the harness like I suspected after seeing the composite log posted by Shane. I corrected this.
But I know the TPS and CLT were wired correcly on the harness and functioned fine on the stim, but I checked it against 3 different diagrams to be certain--plus those functions had always been working when it was an MSI and I didn't touch them when modding to MSII. My only guess right now is that the ground in the engine bay is missing. Correct me if I'm wrong, but I'm pretty sure that would cause the CLT sensor to sit at 180°F (which is failsafe IIRC) and the TPS to sit at full 5v. Unless there's a ground in the engine harness I missed that's required, ...acutally now that I think about it I almost remember something to this matter. I think I did the three grounds above and not to the 3F as well, that may be what's missing here. Yeah, now I'm pretty certain that's the issue. |

The missing ground was the problem. All sensors are reading now!
I have made two attempts at starting, and it has not fired up yet. Attached is datalog, msq, and .ini. Let's get her started!!!! (help me please) edit: I guess I can not upload the .ini |
getting RPMs in TS? I cant see those files here at work.
EDIT: looks like youre getting some reading, can you do a shot of the composite logger again? |
Yes, I am getting RPM. Reads around 160 while cranking.
For some wierd reason, I can not open the composit logger. It is greyed out, and I can not click on it. Will try to reboot everything and try again. |
oh yeah, that's due to the firmware.

Is this far too rich? I have req fuel at 11.9, and I am still using the stock 99 injectors.
Whats up with the GEGO? Also surprised where the MAP sits. Attachment 186018 |
doesnt seem to be spinning fast enough to pul lenough vacuum. sound like it's struggling?
|
Not really. I put jumper cables on to up the charge, and still spun at that speed.
I also lowered cranking speed in the settings to 160 as well as lowered cranking pulsewidth. |
Pulled #1 plug. Smells like gas but is not wet.
|
The actual cranking speed is low, get a decent battery. You are not pulling enough vacuum and your cranking pulsewidth is also low if you still have the stock injectors in.
