I got my newly built motor, and MSnS (v3 board, v29q2 firmware, low impedance 450cc injectors in peak and hold mode, running spark off MS board, Zeitronix WB) setup to start the car on the FIRST crank! It took me a little bit, but after about 30 minutes I got the car purring as smooth or smoother than stock.

I have the stock ECU controlling my Jeep TB's IAC motor, and it keeps the RPMS VERY steady, running 8* ign timing at idle, and ~14.0 AFR.

I kept on getting this intermiddent super rich condition at idle, which would make the engine studder and almost die. Turns out the default Accel Enrich settings were causing the Accel Enrich to trigger, so I just raised the threshold, till it stopped triggering.

I only drove it down then back up the driveway, but let me tell you IT WAS AWESOME, hahaha.

I'll be starting my actual driving tune tomorrow.

Special thanks to Matt (XtremeRS) for hooking me up with his base ign table, and gilee for asking a lot of questions so I didn't have to

That slight .1v TPS change that would happen every now and then is due to the engine vibration from the Prothane motor mounts, and solid front mount.

Just pull up the realtime window to track down what's going on if you're having idle problems.

Nice! It's a good feeling isn't it? Now you will find yourself with the laptop out all the time and making adjustments here and there...on a daily basis lol.

If you ground the TPS ground wire to the MS it helps with voltage stability.

I'll do that. I think it's from the actual throttle body vibrating though, it doesn't seem to be changing fast enough to be noise, but I'll still try it.

Thanks for the tip.

Good to hear you got it going!
Are you only doing Fuel right? no spark right now?

I bascially got my Fuel all tuned right now! Very happy! Since I rebuilt my engine, I cannot get it to boost for longer than 5 sec. EGT will shoot rocket high.. now I boost all day, and it's below 1520F. (only 8-10PSI right now) I love it as well! so you will love it when you start tuning it!

I gave up on the spark for now. Just switch back to my Stock ECU. Somehow whenever I use spark, the car will JERK like crazy when I get to like 3000RPM and ~70-90Kpa. it jerk so bad, it's not drivable. but as long as I keep the acceleration super slow and RPM low, I can go up to 50mph or so. very odd.. I just cannot figure this out yet. so if you got to SPARK, and it works, let me know wick!

BTW, about your TPS, after the first try out, I also tapped and ground the TPS to my MS. and it has as solid as a rock! try that, it might help alot!

For my RPM... It just surge like crazy! I already replaced the crank wiring with a TV coxial cable (shield to MS ground) and I also used a 0.1uF capacitor at C12 to absorb the spikes... but still no good. I just don't know what I can do for that either. you have tthat problem? The RPM spikes usually happen once I get above 2000RPM or 2500RPM.

Good luck with your tuning! I am still trying to fix small things here and there. But overall, I love it! felt like my car is STOCK TURBOED! very smooth!

Enjoy!

Its good to hear you finally resurrected your car, I'm really excited to hear what your car can do with such a nice turbo and now a nice engine management system to match

I really need to get on installing my MSnS..

Yeah, I found the problem looking in my datalogs...

Getting tach spikes once getting to around 2500 rpm's...

I ran a damn shielded pair to the crank sensor (signal wire, ground to MS, and wire shield ground at MS only), and it still get's damn spikes.

Joel Baldridge, ASE Certified Master Technician, Audi Certified Expert Technician

Yup... that's the problem .... I did more tuning and logging today to see why running spark is horrible. and what I can only think of the problem is the RPM SPIKE! seems like whenever the SPIKE happen, the car will lose power (coz now MS control the spark) so the problem is whenever the RPM goes above 2500RPM or so, RPM SPikes goes so random and often..

I also shield the SIGNAL wire from the crank position sensor. But did you completely CUT off the sensor and applied volts and ground for the sensor? I only connected one shield wire to the crank sensor.

DAMN how others get their SPARK going!... shoot.
