they are. honestly the sizes of the injectors dont matter as much as say on aem or kpro.

 

well just got back from driving up the block under 4k and the car was running lean so i had to adjust the i/j to 2.1 which is still a 10.0 a/f at idle but im going lean in between shifts now but normal driving is fine.im wondering if its because im tuning using throttle pos instead of airflow pressure

 

just went out for some street tuning(WOT) and everything worked out great.if you decide to street tune your gonna need someone else to drive your car so you can make adjustments on the fly.one of my intercooler clamps blew off so i clocked the charger and ran it direct for 12 psi.(holy shit)the emanage a/f target is pretty good at making some of the adjustments for you.i tried a/f vs psi and pressure but i found in the end vs rpm is actually eazier for myself while dataloging.i am still running pig rich at idle and really any closed loop driving.btw i used a turbo map which i knew would start off to rich to be safe.we worked from 3-5k then 5-7 then we went up by 500rpms till we got to 9k whcih from 8400-9000 it was running super rich.

I will build you a map tomorrow morning.

It was out all weekend.


Take off the FMU/RFPR and go back to stock FPR or an AEM equivalent set at 50psi with the vacuum line disconnected from the FPR. With larger injectors the FMU/RFPR is making it very hard to tune your setup.

Questions
I need to know are you still runnign the stock MAP or a Greedy pressure sensor?
If you are running the Greddy MAP which option port do you have it plugged into?

And your A/F sensor if you are not running the Greddy MAP which option port do you have the A/F going to?

You said you had a 12psi pulley on the blower with the front mount how much pressure loss are you experiencing. AKA what is the max manifold pressure you are seeing?

 

BTW your lag times are way off

Usually the lag delta between stock (360) and a set of 550 or a 650cc injector is only about 0.5msec at 14.4volts.

 

im not sure how much boost i was making since the intercooler pipe blew off the second time we went wot.i am using the stock map sensor.option #1 for the wideband.lag delta is off??? so should it be stock at 1 sec and 550s at 1.5 sec?

 

oh btw my a/f was set around 11.2 at wot.someone was telling me low 12's would be better

 

Your final A/F all depends on how well your timing is dialed in and what your IATs are. To much timing can be just as bad as to little timing when it come to EGTs and performance.

For now mid 11s is good once you get the map then we can start leaning out the A/F to a more ideal 11.8 to 12.0.

What is the ethanol content of the gas you get probably E10 ; this can change the ideal A/F you should be looking for being that you have an Bosch A/F probe instead of a lambda probe.
11.8 on a A/F probe with E10 is really something more like 12.0 to 12.2


In the map I will send you tomorrow once I get to work will have 0msec as the lag time in the OEM (before) block and .5msec in the after block.

AKA average .5msec delta in lag time between the stock and the after market injectors.

Again take off the RFPR/FMU and go back to stock.
You are trying to tune in the closed loop areas with the ULT, with a FMU that is probably running to hi of a rail pressure at idle and scale for the 650ccs.

You are fighting the stock computer right now.

Once you get back to the OEM FPR and the 650cc injectors with the ULT Scaled correctly you should not have any problems when in vacuum areas.

 

thanks im running 550cc injectors BTW.not sure what e10 is but the fuel grade is 93

 

550 got it.


what DC% output is the UTL showing you are running?

E10 is 93 oct with up to 10% ethanol.

If you still have pure gas in you area consider yourself lucky.
