Re: (malta18T)

This week i changed temp sensor and I think that changed all !!!!!! The old temp sensor I logged with last time I think it wasent working well, reason is that car was all rich over 3500 rpm with 4 bar FPR and 3 bar FPR, no change in AFR when changing pressure so I kept 3 bar on there as car was drivable more than the 4 bar ! Went agian this evening, changed fuel from race fuel which logged today and back in local pump gas ! AFR kept being the same !!!! 14 - 13 till
redline !!! Went back to the garage put the 4 bar FPR and then I was
going 12 AFR till reline + Car was much more powerfull than this morning !!! couldnt see well all AFR but that is how it worked !!!
So I am assuming that the old temp sensor was faulty ?? and was riching the car all the time ???
What you people think ??Please help me
As soon as I will install FMIC I will log everything on the dyno

i used ELF unleaded 102 octane, but as I said I was running a 3 bar FPR and car was running lean !!!
Put in 4 bar FPR and A/F is much better but I finshed the race fuel and put in pump gas agian. I think the temp sensor screwed up everything for me !!!
I will re log when ATP FMIC is on , I will log all on the dyno with pump gas and race gas + bhp also , they those will be the final logs that will go to jabba to re tune my software

didnt know if was or not, just changed it and then found differences
With old temp sensor with 3 bar and 4 bar FPR A/F was 10.8:1 till redline with both, no change at all, with new sensor with 3 bar was 13.5 A/F and with the 4 bar its 12 A/F
understand .??

but before with the 3 bar FPR was running 10.8 A/F, changed temp sensor and went up to 13.5 A/F, thats why i say temp sensor was reading badly, yes its race fuel done by ELF , its the same fuel they use in WRC !! infact its super expensive !!
