I am having issues getting my car to rev up. Work execellent until about 5500rpm. It just doesn't want to rev. Very light throttle help a little but as soon as you dip into it feel like hit rev limit. I have posted my log and msq.

 

You posted this to msextra.com did you not?

 

Yes I did post it there too. Maybe it could not just be rx7 related. I am pretty sure it is from being to rich. I was able to run that rich before without problems. But with the sequential the want to be much leaner. Wierd. I just don't like to lean it out till I know for sure that what is it is. I did lean it out some and it did improve. I will lean it out even more but I don't like running lean under boost. I want to run 10.8-11 to be on the safe side.

I am running very exspensive ceramic seal on brand new housing so I am trying to be cautious.

 

Low 11's seems OK to me... The turbo rx7 I tuned didn't like to be much leaner than 11.3-11.5:1 There was a definite loss of power below that, and it definitely didn't run as well.

Ken, you think this might be the same thing that happened on my car?

 

I got it running pretty good now. I pulled some timing and fuel and it is happy now. I am shooting for 11.3 -11 now. I was going 10.8-9. But for some reason porting it change the afr requirements. Thanks for the advise.

 

Nah, you have something going on with your CAS inputs and/or grounds.

I don't think this is that.
