Its a second to none ... more precise on controlling the boost ... no boost drop issue no spike issue .. comparing it to the greddy ? u r so mistake by comparing

 

LOL! I've been there, done that, now I'm happily back to PCs.

 

For sure u r right .. it will be my next upgrade

 

Told them exactly what I do with a computer, none of the programs work on this and then they said I can split the the something and run half the way it is and the other half with the system needed to run my other programs.. No thanks, now I am trying to get a laptop that has a serial port..

 

can you log injector duty cycles?

a 16g at 1.2 bar will max a 5bar, sounds like you're out of injector

 

what version of durametric are you using?
we have seen high rpm AFR logging issue with the latest version.

 

i was data logging with the latest beta version .. i will do a data logging again with the previous one.

 

i was also thinking it might be a problem with a vacuum leak between the MAF and the turbo inlets. so i have air going in without being read by the MAF.

do you think i should check that before i do the test runs. would that kind of leak also have the effect of lowering idle do you think? the car idles at about 850 rpm. the tune on car is supposed to idle at 1100 rpm.

 

My educated guess is yes, since fuel is metered by air flowing past MAF and if you have air coming in after the MAF it would not be taken into account and you could have lean fuel condition.

See if Todd can provide you with a MAFLess tune and then get rid off you MAF's.

 

I just did a run. the hks evc read boost at 1.05 bar but on the datalogging i got up to 1.13 bar. the injectors seem to be running at max cycle 27.8 ms at 6000rpm and 22.15 at 7000rpm.
so next up is fueling but im still worried about maf. I dont know how a mafless tune will hold up in weather where it goes up to 50 degrees C in the summer and 0 degrees at night in the winter. any thoughts?

 

get the injectors and a tune.. maybe some decent ICs and leave it alone... Ive set up many guys like that and they love it.. maybe add the intake piping

 

Will count on ur advice

 

something is wrong if your your injection time is correct

120/6000*1000 = 20 max injector time but you are at 27.8
120/7000*1000 = 17.14 max injector time but you are at 22.15

either case you are way over 100%duty cycle.

You sure need to upgrade your fuel injectors.

Talk to Todd.K and seek his advice.

 

malfess tune only ovaliable for 997 turbo not 996 turbo

bigger injectors is a MUST!!!!!!

 

I dunno.. i think i saw a 996 with mafless setup for some one here in 6speed but am not pretty sure.
