Ya I got screwed, I paid to have it fine tuned on the dyno at $100 an hour. I thought it would only take a hour or 2. Then when i picked it up they said it took 4 hours and that because I dont have a idle valve it dies. Its all B.S... No matter its all taken care of now. I will never take a car or ...

I tried to do that, the Dude said that it was because i did not have a cold start valve. We all know that is crap. Then He said that it was a mechanical issue with my motor. Wrong again. I will not be taking it back to them. It cost me $400 the first time and i am not about to get naild for any more ...

So here is the deal, I have always done my own tuning. I have been doing it for more than 4 years. I took my MK1 16v GTI to the dyno, the Dude that did it also did some tuning to get more power out of it. So since then when ever I run out a gear, Like over 5k, 6k, and go to shift it just craps out ...

I paid for the full version, best thing I ever did.

Mine idles at 14.1 to 14.5 and its a nice idle. On start up it is about 13.6 and slowly goes up to 14.5. It runs and idels perfect.

Well i guess i have a update, I have been doing a lot of tunning the last few days and the stalling issue has seem to go AWAY. I changed a few of the constans and played with the timing. But the biggest improvment cam from using the auto tune in Tuner Stodios. That is the best program I have ever ...

Yes i did have a ground issue,I got it sorted. I have not done a good Log in a wile. I will get a current one up soon. Here is the new MSQ for you.

So i did some work to the rabbit today and found that one of my fuel lines was leaking on my 255lp. I fixed it and am hoping that fixes my issue.. I have not had a chance to drive it yet but i will tomorrow. If this did fix it i will be verry happy.
If you think about it when i need the fuel, like ...

I am running an engine very close to this setup and I am having all sorts of problems too. intermittent stumbling issues under acceleration. Im looking at your msq file and found it is considerably different from mine.

one thing I do not have trouble with is with it dying when I decelerate ...

well did some changes today, redid some grounds and ran a new one from the battery to my main ground point on the body and then over to the motor. I hope this will help with the dwell jumping. Its been raining here the last few days but its going to be nice this weekend so i will be doing more ...

Ok i will try that. I am going to be doing some work on it today so i will change the grounds around and maybe ad a few just to be sure. Thanks for all the help..

as for as i know they are all good, Why is it so important with low Impedance injectors? all my grounds go to one spot on the frame. I am running a mk3 power disturber for all my power. The one that mounts on top the battery with all the fuses.
My battery is in the back of my car. Not sure if that ...

I am running low impedance injectors. I have so High but their a lot smaller. the ones i am running are 300cc and i like them. Is my PWM wrong?

Ok so i made some changes and still have the same problem. I would like to know why, in my data logs that my dwell jumps? it seems to happen when my car stumbles, or it making it stumble. here are 3 new data logs..

So i raised the MAPdot Threshold up from 100 to 208, my TPSdot is at 208 I have it set to 100% MAP. Question: would it be better to run this at 50%map & 50%tps?? I will be trying this out later today if the rain stops. I have to make the changes to the 2k VE bins as well.
Thanks For the tips. Any ...

I am running low impedance injectors in my MS 2 3.57. they are 300cc bosch green top. I have never had any problem. I have changed from High to Low and back a few times tell i got the right fueling that i needed. Just my 2cets.

Thank you for the input, how do i fix that problem?

Ok here is 2 of them, One is driving and the other is in the shop just reving past 5k so i could show what is really going on.

So here is my issue;
I got my MS tuned great i am making sweet power, 183.5whp @ 6250rpm
My AFR is right were it should be, BUT when i am at a high rev like over 5500rpm and i let off the gas it just dies. It starts back up fine and idles great. However just reving it in the shop over like 5500rpm ...
