Thanks joecar for the explanation. :cheers:

If I want to trim fuel to compensate for meth injection I will have to do it in the {B3647} commanded fuel table or make it leaner than the {B3618}.
...

The way I see that is commanded fuel will come straight out of {B3647} with no multiplication when {A0008} is set to 1. {A0008} is used to provide enrichment while the engine is warming up. I don't...

I don't think that is PE that you are seeing in the log. It is commanded fuel from {B3647} as far as I can tell. The actual AFR is a result of Commanded Fuel from {B3647} plus Boost VE {A0009} and...

Been running with STFT Idle Enabled for a few days and everything seems to be working.

I was told the COS3 (maybe any OS) would go to whichever table was richer. In this case it is the B{3647} . I am going to try making PE Mode richer and see if PE activates.
Onward and Upward.

Thanks for the heads up....:funnypost:

Am I left to assume that PE Mode cannot be activated in COS3 OS 03190003? :confused:

I have attached my current tune and a log I did yesterday. The commanded fuel in the log equals the fuel commanded in {B3647} and not PE in {B3618}.

I activated PE after having it turned off for a long time {B3613} set to 285 kPa.

I have {B3608} set to 0 sec and {B3613} set to 130 kPa. {B3616} is set to 50% TPS in all cells. PE does not seem...

I re-enabled {B4108} STFT Idle Enable in COS3 to do a RAFIG and RAFPN. Can I leave the the trims enabled? Will it bother the operation of the COS or the Commanded Fuel tables {B3647} or B3649}? Do...

Trying to do a RAFIG?

Well I am back in business.:cucumber:

It seems the problem was in my laptop. Not sure why? I updated windows and did lots of shut downs and it worked. For some reason EFILive would not read the...

I have flashed it hundreds of times without a hitch, until now.

I tried to flash my PCM but it says it is not licensed. Well it is, so now I am not sure what to do? Need some help!:help2:
Thanks :doh2:

Hey Jon ... I used a tune from a 05 Vette LS2.

I have a set of Bosch EV14 flowing 624cc at 58 psi fuel rail pressure that I replaced a set of Multec II 44 lb/hr shorties with. It has taken a while to tune but they seem to be working very well and...

PE mode is activated by Throttle position {B3616} at given rpms (mine for example is 50% all rpms). Some people like to set them lower depending on when they see boost. I was not seeing any KR so I...

5.7ute, Thanks for the suggestion. I am going to try that to see what I get compared to my current and future settings.




Howard, Thanks for the explanation. It helps as now I have a better...

Thanks John, I was thinking something along those lines. I have B3647 set to 12.5 at 105 Kpa above 4800 rpm. I run PE and keep the B3647 a little on the leaner side on the theory of improving...

Added my signature in case that influences the situation.

Good question. I don't know for sure. Mine is still considerably lower than that and follows the original scaling.

Thanks guys! :cheers:

I'll try it at plus 200% and see if working on my Boost VE helps with this issue.

I have done and am working on the Main VE, after installing new injectors, but have not done much with the Boost VE. I see a very select number of cells and I am running PE so I did not bother but I...

I have a problem with Commanded AFR vs Actual AFR. It seems I am running 2 points richer at WOT than Commanded.

I was wondering what the relationship is between PE and Boost VE.

I have PE set...

I am getting this code at WOT on the shift either from 1-> 2 or 2 -> 3.
