Thank you. As expected. I am leaning toward the MVPI2 so I can continue to tune my 2000 Trans Am and some other cars as needed. I appreciate the input. RPM and Throttle would be most helpful. Boost...

Hi there,

So I have been using TrackAddict for a few autocross events lately and like the app very much. I am considering purchasing an MVPI2 so I can log additional parameters in the app. Is...

So I believe the idle is *mostly* done! I think I'll pick on the adaptive spark stuff some more but all in all it is really close now! I used the scanner to log desired airflow and then input that...

Well after considerable research I am working on getting the BRAF table dialed in first.

I am thinking that is the cause of my hang as the STIT is running around -6 yo -7 g/s. So based on the...

As an example my stock tune file shows Hi Octane table values for .24g

400, 600, 800, 1200, 1600
18, 18, 23, 28, 30

In Park Idle table at the same .24g looks like this:
0, 400,...

I believe the idea is to keep all those tables very close to the same so there are no big spark transitions when going from park to gear ETC. I believe from the factory they vary a "decent" amount...

Ok, she is idling now. Sort of... IAC counts are much better. It idles enough to get her up to operating temp so that awesome. I think the next order of business is friction air flow. I have no...

Thank you!

Thank you for that. I didn't realize you had to still fail the MAF using the SD OS. I must have missed that somehow... :( I did fail that and now it is starting to idle a bit. Progress!!!!

I guess...

I would agree with you except the plugs are literally wet.... Two have fouled and won't fire. Had to replace them. All plugs are BLACK.

TPS voltage is the second line in the scan. The TPS throttle percent is in the graph. Should that be in the table?
Is there a different PID I should scan?

It's basically Russ K's cfg with the...

There should be TPS voltage in there maybe I uploaded the wrong one. Stand by

Here it is.
86620

And the scan from it
86621

Thanks!

Hi Travis,

Sorry for the delay. I have stepped away to try to get a fresh perspective. So far I can only get the car to idle for a max of 20 seconds. It still won't take *any* input from the...

Well I am starting to get stumped.... Tried three more tunes tonight and not much changed. The REALLY odd part is the timing in the last scan is all over the place (low) and there were no changes...

The IAT sensor is reading as it should. Shop was ~57 degrees today and that is what the IAT was reading.

So I am starting to make some progress I think. I used the VCM scanner to command 14.0...

5FDP I think I see what you are saying now. The log file isn't monitoring that sensor not that there isn't data. I have added that to the logs.

If it wasn't reading the IAT should/would it throw a DCT? Just curious as I have not seen a DCT for IAT issues. Researching now.

Hello everyone,

kthunt, good call I should have mentioned I lowered that setting. In the idles cells the minimum is .790ms

5FDP, interesting. I hadn't looked for the IAT reading in the logs. I...

No idea why it is commanding the AF it is. Digging into that first. Also, spark seems lower than it should be.

Thanks everyone.

Well that didn't work. I'll get the latest tune file and scans up asap...

Also, in doing more research I *think* I might have a solution. At the very least I have a next step!

I was trying to get the AF down so I was lowering the VE table in the idle regions. Then I...

Hi Mike,

I posted the tune and logs in the first post although I didn't test to be sure they could be downloaded. I'll do that now. Anyway, this is 100% open loop no O2 sensors. It's a drag only...

Couple more details I should cover so as to not waste anyone's time.

I have checked the grounds and they are solid and all connected
Fuel pressure is steady at 58 PSI (bypassing style fuel...

Hi all,

I have been searching and trying to find a solution to my issues. Newbie warning of course... Well, new to HP Tuners and LS tuning but not new to EFI or racing. I used Accel DFI "back in...
