Tune Help

[Jeckel]

Hi guys, It's been awhile since I have worked on the tune (or even driven) my GTP. I have it so there is no KR until boost hits. Is there a way I can upload my tune and have someone look at it? Give me some ideas?

If your afr is set 11-11.5:1 then you need to pull some timing.

Thanks for the reply Ginseng!

I already know that I am also running the bad fuel spark table where the good fuel spark table is to help with the KR issue (it does help). This is why I am in need of someone to actually take a look and see where I am going wrong.

I saw a reference to some guide Reptile put together. I can't seem to find it tho.

What do you tune with?

Its as simple as pulling timing in the spark table where you are seeing the spikes of kr. I dont understand what you meen.

I have a DHP.
2000 gtp
MOD list:
9" cone filter
4" pipe to TB
N* TB
LQ4 MAF
ZZP ported Gen 3 SC
Opened up the LIM
3.8 MPS (KR seams to stay the same regardless of pulley size)
65# injectors
1.8 comp cam RR
SD Headers
3" exhaust to the rear wheels then stock mufflers
3" hi flow cat
no resonator
Bottom end of motor is from a 2006 lacross
Top end is l67

I think that is all.

I mean I have already pulled timing. with the way things are setup right now, I am either missing something very important, or there is a fuel issue.

I assume you have a wideband? What are you reading under boost? What is your timing hitting under boost?

I have 0 experience with dhp however with the bigger maf and injectors you're dealing with its a possibility you might be dumping to much fuel when power enrich hits.

Regardless a wideband could really help diagnose your issue. You can use Google drive to upload your tune

I have already tuned for the larger injectors. and for the MAF. I do have a wideband, but it started powering on only when it wants to. I need to dive into that problem as well.
