3.0.3s is the serial protocol.

If you open the XLS I sent you, on the "Tests" tab, item #34 is "MS2 firmware loaded". In the "Notes" section is the fimrware version you have. You should have 3.0.3v. The firmware version is also displayed on the titlebar in TunerStduio, when you are connected.

What's your current target boost level in kPa btw? I would recommend altering you map so that if ie your desired boost is 200kPa, you have one row at 190kPa and another at 210kPa. That will allow more precise fueling.

Start over with the basemap, and see where that gets you.

My boost is set to 210kpa but creeps up to 220 in 5th. Never went over 220 though.

Yeah I'm definitely starting over. Sorry to have cluttered up this thread with my weird problem, but I just didn't know where else to ask. I've been reading so much on this stuff and yet still have so much more to learn. My head is spinning, and I just want my car running right again (like it did earlier during the week)

Its a bad idea to calibrate anything (AFR, TPS, temp sensors, etc) while the car is running. Switch the ignition on, don't start the car, calibrate, switch it off, then on and start the car.

I would try this trick: Switch the ignition on, and let the wideband warmup fully. Once its ready, compare the AEM gauge with the wideband gauge in TS. Note how much they are off. Now, without starting the car, go and calibrate the AFR table by setting it to "Innovate 0-5V 10:1 - 20:1". Once its done, switch off and on again. Let the sensor warmup, and then compare the values again. They should be somewhat off now. Now recalibrate with the AEM Linear settings. Off and on again, start the car and let the sensor warmup. Readings should be within 0.3 AFR between the AEM gauge and TS with the car running.

I also had this problem. I tried the calibrate AFR table with LC-1 0-5V 10-20AFR. I double-checked my LC-1 settings and still was about one point off in TS. I found the option to set custom linear wideband settings in the same "calibrate AFR table" popup. I entered 0V for 10AFR and 5V for 20AFR and it is now spot on. Looks like there is a bug in the default LC-1 option in that popup.

I set my cranking settings from 300RPM to 250RPM and cold starts are better. I changed my PID settings and AC,PS and other loads are handled pretty well. I am still getting some oscillation in my AFR at idle. I'm not sure if EGO correction is causing it. Here is my msq file and a log for you experts. I made sure ASE and warmup enrichments were not in the temp range to affect my idle.

Thanks in advance.

Here is the log file... unzip to view.

I found that it was EGO correction affecting idle. I raised the min kpa to above my idle range and all is well. I changed it from 25 to 30.

I changed the accel enrichment settings from 2500-5000 to 900-7000 based on info from the manual.

I am getting some slight hesitation in partial throttle cruise. Any ideas? More auto-tuning?

Edit: It seems that it is scaled from 100% to 0 from the lower to the upper bound. So I will change the lower bound back to 2500 and let it taper to redline.

How is the LC-1 wired in?

Reverant

iTrader: (10)

This means that you need to fine your VE at idle. I never had oscillations during idle, which is why I keep having EGO correction enabled during idle.

Thanks for the feedback Dimitris.

The LC-1 is wired to the fusebox (hot with ignition on) with a 5A fuse. The brown wire (Analog 2) is programmed for linear output from 0-5V for 10-20AFR and is connected to the ECU. My gauge is the XD-16.

I'll fine tune the region for Idle. It stays within a cell, but I'll change it to stay in a set of cells. I did notice that the timing also fluctuated from 10 to 13, but timing and AFR was stable without EGO correction enabled.

Where are your grounds connected? You can connect the blue wire to pin #2 and the white wire to pin #3 on the DB15, that will get you much better results.

Btw its best if your idle stays within four VE cells, ie if your idle is at 30kPa and 1000RPM, set your VE table so that the RPM cells are at 900 and 1100rpm, and your load cells are at 25 and 35 kPa.

I was going to suggest using the Idle VE table, but forgot that's a MS3 thing. I still personally do not like EGO at idle.

My LC-1 is grounded to the chassis under the dash at a wiring harness ground point. Right now it is spot on with TunerStudio. I also lowered the sample rate of the LC-1 to 1/16 sec. because it was very sensitive. I idle at around 22-24kPa, so I modded my tables load cells to start at 20 then 24.

Do you see anything out of the ordinary in my .msq? It is in post #124

I picked up Staffah's MS you guys built for him. I have a US '99 with COPS; is there anything hardware wise that will need changed to use this:

No, you should be fine as-is.

Reverant

iTrader: (10)

Bad. Redo your grounding on the LC-1 per my instructions, then redo the AFR table recalibration in TunerStudio.

I FINALLY figured out what was causing the lean-ness.
Such a stupid thing I am almost too ashamed to reveal it

Somehow my "AFR target" under "more engine constants" got changed to "don't include AFR target".

Flipped it back to "include AFR target" yesterday and the car runs great again

Holy **** was that a pain in the ***. Such a stupid mistake

It is your Accel Enrichment.
Mine is disabled.
When I enabled it my car would go crazy at part throttle. Studders, shudders, jerks, etc.
Turned it off and its great again.

I'll have to read up on how to set AE so that the car doesn't do that, but I know for sure its AE causing it to stumble and jerk at part throttle.

Reverant

iTrader: (10)

Nope. Your basemap did NOT came with that option enabled.

Reverant

iTrader: (10)

You need to switch it on and tune it properly. Your car is somewhat different than all the other cars, since you have 1000cc injectors AND E85. So your settings are bound to be very different than all the other cars'.

Just to give you an idea, your basemap came off the blue 430hp car. That car had 1000cc injectors as well, just not on E85. And it does not stumble, jerk or hesitate whatsoever.

99mx5, you probably have some areas in your map that aren't autotuned yet.

18psi

iTrader: (76)

So I should switch the AE back on and let it stumble til it auto tunes the stumble out?

Also should it be "ONwith lag compensation" or just "ON"?

Also should the thresholds be 2500-5000 like its set to on the base map or should I expand it 700-7000 like 99mx5 did?


With AE off the car doesn't stumble, jerk, or hesitate. It runs great. With it on, when I'm at part throttle and decrease throttle it stumbles and jerks.
