Hi,
just wonder do tuning maf smoothing improve response?

Its my same old problem where whenever i immediate full throttle, my afr will deep til 10afr which my car seems hardly accelerate.
Ive to immediately partial throttle and full throttle for 2 to 3 times only my car will catapult.

Ive done with my injector scaling and latency but with no improvement at all.

Have tried increase timing on lower load from 10~70 - RPM from 1000~2500

LS disable all the time and im on 850cc Sard injectors.

This is my last only problem which i dont mind to pay a contribution if whoever can help me on this issue.

Spec's :
gt3076r
S2 cams
85.5 piston
300 x 600 x 70mm IC

Or the fact is its Lazy Spool or The Bigger CC Injector that im using???

Pls do not ask me to go for ALS.

 

have you retuned the spool area of your fuel map yet? i keep seeing your threads and that simple question never seems to come up.

 

Hi Penquin,
honestly ive no choice as this is the only remaining problem i really hope to solve b4 i give up and go either for :
1) Change back to stock 560cc injectors
2) Smaller turbo

Most of my problem have been resolved and which ive got most of the kind advise & sharing in this forum...

 

have you posted any logs?

 

You can't simply turn LS on and off without retuning your fuel map to compensate.

If you state your injectors are dialed in to at least +/- 5% low/mid trims then post 3rd gear logs starting from 2k to rev limit.
Make sure you log the following and NOTHING else.

- TPS
- RPM
- Timing
- Injector duty
- Injector pulse
- Knock
- Wideband AFR
- AFRMAP
- 2byte Load

 

I already told you via email, that your spool was where it should be (gt30+S2's=4000rpm peak boost). If you wanna improve response, go with a smaller turbo.

Also, if you having too much fuel during acceleration, mess with the accel enrichment tables.

 

Thank you Benja will do it and post the log here.

 

Hi Jay,
yes and thanks for your kind advise as i understand that i cant expect my gt3076r response as a stock turbo but my main problem is the super rich afr whenever i immediate full throttle which make my car heavy until ive to immediate partial lift off and re-throttle again.

Lastly, mind to advise me on how to set the Accel Enrichment table for a better AFR & Response on my case?
I noticed that the A.E will adjust by itself everytime we adjusted the Fuel map or Timing map (I might be wrong)?
1) From which RPM should i start to dial?
2) To lower or increase the % for leaner or richer afr?
3) Do i need to retune my Fuel & Timing map again after adjusting the Accel Enrichment and other area i should adjust as well?

Thanks Jay.
