Default Trying to get the Adaptronic to work on my car

Ok, so being electronically challenged this is turning out to be a bit more challenging than I thought.

After finally figuring out (after being helped by you guys) which wire is which on the tps to wire in the MAP, I installed it, downloaded the software into my laptop to get this thing started, and plugged in the wiring the Adaptronic came with. First of all, the directions are really not specific at all. I basically had to fiddle with Flashit (or whatever its called) till I could get it to read the com port.
Loaded in steins map, and tried to give it a crank. No bueno. Starter spins and spins, then for a second car seems like it will start only to start making crazy compressor like sounds and die very abruptly and unhealthy sounding. Adjusted the map to read from the narrow band oem sensor (the wideband isnt wired in yet).......Gave it a go, again sounds absolutely awful and wont start. So I load in the base map that is posted at BoundaryEngineering....The car, after a few unsuccesfull tries starts, but sounds HORRIBLE.....Some REALLy weird sound coming out of it, like a compressor trying to pump up tires. I immediately shut it off, load steins map back in and try it agian. Again no bueno. Call travis, he's not picking up (its a saturday so I dont really expect him to).....fiddle with it some more......nothing

I am out of ideas. Like I said before, I suck at wiring/electronics, so I dont even know where to start troubleshooting.
Travis, if you read this man feel free to call me 916 753 5598 or just let me know when is a good time to contact you so we can try to get this sorted out. The car started before on the stock ecu and idled. After it warmed up the idle was very jumpy/rough and the car was putting out a shitton of smoke, but it ran. After fiddling with the tb idle screw, idle stopped jumping around, but the car still smoked. Now it will absolutely not start.

Going to read through the manual again and again to see if Im missing something.

The reason I posted this in a thread is to maybe help out people that will be going down this same path. Hopefully when I get this sorted out it will help diagnose these problems.

When you say it ran like **** on the stock ECU, was this with the AFM not wired up perhaps? What about the factory O2 sensors? It should idle ok on the stock ecu without the O2's, but I dunno if it would without the MAF sensor. You need to figure out why it's not right on the stock ecu before introducing more variables, IE-the adaptronic. Perhaps you need to switch the plugs on the coil around because the firing order is backwards when the adaptronic is controlling the coils. Can you datalog anything? That might help. Is this with stock injectors?

I just sent you my latest map. If you don't have the WB hooked up you won't be able to tune the idle. You have my phone number now.

Great, thanx
I'll start wiring in the wb02 now then, and give it a shot on a more recent map tomorrow.

stock injectors. when i had it running stock ecu maf was plugged in and plumbed in. I would hook it up to throttle body (with turbo/ic disconnected) it ran flawlessly. i then hooked it up to turbo inlet and connected ic/turbo to engine. idle became rough. It was running on only 1 o2 sensor, the other one was disconnected. with the adaptronic now it really sound like the cylinders are firing completely fucked up for some reason, now that you mention it. I will have to take a look at that, but first and foremost I'm wiring in the wbo2 and connecting it to the adaptronic.

Stein - thank you so much for the convo over the phone, you definitely opened my eyes a little bit

Ok, today I tried to get it to start again. I am starting to think its a spark problem or something along those lines. Car cranks for ever, does not start, if I touch fueling you can actually SMELL the fuel its so rich, then I lean it out and after cranking for a minute or so there is a HUUUUUUUUUUGE backfire that sounds like the car just exploded, and it just keeps cranking. Does not start

Yo have your WB installed? Is the WARI configured for it? What does the gauge say when you are cranking?

Like I said sounds like the coils are reversed. Try switching the plugs on the coil packs around. Also remove and clean or replace your plugs. Then try starting it again.

not yet. I drove to radio shack yesterday after speaking with you and they were closed. Then went to Fry's electronics and they had long *** cables for like 30+ didnt want to spend that kind of money just for the connector. I did route everything just like we discussed. All I have to do is find the db9 connector. Monday I will have it up and running. The only reason I tried to start it yesterday is because I needed to get it back into the garage (steep incline).....after many attempts I just called a few buddies and they helped me push it inside in exchange for beer

I'm beginning to thing the same thing. Its GOT TO BE ignition related. The fueling is there. The starter spins for ever. New plugs going in tomorrow as well as wb02 being connected. I will also call up Travis and see if he has any ideas. Dont see him posting so maybe he's out of town or something.

Just got off the phone with Travis, he sounds SUPER sick.....Tomorrow or the day after after the plugs are in and wbo2 is connected I'll be in touch with him for further investigation.

Default Update

Well here is what happened yesterday:

https://www.miataturbo.net/forum/t32729/

Today I got a voltage meter and tested the TPS wires with the MAP sensor connected and without.

When the TPS is on its own, the +5v wire reads 4.92, which is close enough and from what I understand the correct voltage. As soon as I connect the MAP sensor to it, the voltage reads 1.97, WAY LOW. Do I have some WEIRD *** MAP sensor? It seems to be overdrawing by quite a lot. Stein has his wired in the same exact way and it works just fine, but he got mine from Adaptronic and not Egay. Is it possible they sent me a sensor that requires more than +5v to run?

Anywho, Travis I gave you a call but no answer, so when/if you read this feel free to pm me with any more ideas. I'll try to give you a call tomorrow, hopefully you're available.

Strange question? but are you sure that you wired the MAP sensor in the correct way?
Maybe a picture would work. Then I could see if you are using the MAP sensor that is provided by Adaptronic.
Mine is one, and a few friends of mine have the same, the sensor sold by adaptronic is an 5v sensor. So far we don't have trouble with it.
The way we wire it: A=GND B=Signal (orange) C=+5v

What can be an option: connect the tree wires of the MAP to the yellow/orange/brown wires of the adaptronic instead of the stock wiring under the hood. My car has the MAP directly wired to the adaptronic. The other wires are connected by the loom. Works fine for me. Advantage: when installing you can disconnect the adaptronic any time and go back to stock ECU. Then your engine should run like you are used to.

Travis' phone is dead. I was just talking to him and the battery died. I just checked my car. In WARI, at the top click Windows then (ECU Data). In that screen my car show the MAP at 1.73 V with the ignition on but the car not running so I don't think your 1.97 is wrong. It could be the difference in atmospheric between your location and mine.

I think your MAP is wired correctly. It won't show 5V.

Here's some info on the GM 3 bar map. Not sure if the ebay one's the same? It's probably just a matter of calibrating the ecu to the sensor output voltage. You should be able to use a compressor and go from 0psig to 15psig (or is it 30psig?) and see the map output voltage change from ~1.97v to 5v.

18psi what doy you exactly mean by voltage reading 1.97v? Do you mean that your +5v line will drop to 1.97v? If that the case, and you are sure you connected it in the correct way there is a real problem.

If you mean that the output of the MAP sensor reads 1.97v its not that bad. look to the post above.

Default Update!!!!!!!!!!

Ok, so for whatever reason out there, the car started and idled just fine today...WTF!!!! all I did was double check all the connections, touched them, wiggled them around, and then started up the car. I messed with the idle valve settings a little bit and richened up the idle at 30kpa and it just sat there idling for like 10 minutes

The wb02 is still tweaking though, the gauge reads just fine, but on the adaptronic its showing 18.0 no matter what. I then richen it up like crazy, and it goes down to 17.9.....so its getting a signal, just a weak one I guess? I'll have to mess with it some more and figure it out I guess. Changed the settings to read off the narrowband for now.

Then I took the car for a drive around the block. about 1/10th mile total, up my street and back, so no far driving or anything. It is VERY hesitant upon throttle tip in (I guess)..Like I give it a teeny bit of gas and it hesitates, then JERKS the car forward and starts bucking. once I keep it steady though it drives normal.

One thing that really bothered me though: the gauge reads extremely lean while driving. Now I got this map from Stein, so it is fairly well set up, and yet it is still way lean (from what the gauge says).....I'll have to get that straightened out....

so thats the update

Vlad; if it's any consolation; I know my own install is going to be more complicated than yours.

I'll be contacting you and Stein often
