bigger injectors working with new setup

[gts_junior]

Hello Matt

Here is the tune I have with the setup maybe you could find the problem but I am completely stumped.

Thank you kindly

Rob

Log file had no injection time or AFR data in it so I couldnt really look at that

okay using K=153 is a result of the auto calcs based on theoretical values. What are your AFRs like at the moment?

Put injection multiplier on auto and start adjusting this whilst watching your AFRs around idle to get it close to 14.7:1

Also set your 'O2 feedback temp' to maximum value whilst doing this. You still have O2 sensor enabled currently

okay the afrs at 153 injector constant are 12.5

[Matt]

Start adjusting injection time using 'auto' enabled to make the AFRs at idle closer to 14.7:1

Higher should keep on leaning it out. Holding -/+ will make adjustments in increments

Hey matt

your info helped greatly the car doesnt die no more, but every time i m on the gas the revs drop and the car is about to cut it out, i can only give it a spurt of throttle an then wait for it to regain the idles heres a couple logs

[Matt]

cant see injection time in the log. Also AFRs would be nice

Have you got the correct (Z32) AFM in the tune? Probably post the bin file here to check

[gts_junior]

Hey so sorry for the late response here been dealing with some issues here is the bin file

Can you post your current tune here also?

Helping a customer today and the auto calcs do not play nicely with larger injectors and the TP scaling (needs to be pulled back a bit on the scaling down)

hey Matt,
If you don't mind me saying (hehehe);
Please ensure that the auto calc's likelyhood of hitting the last column in load scales is easier rather than more accurate. So many injectors don't flow what they should due to other variations. It's always easier to fix the scaling than replace a split bore !!

The auto calcs really are only a rough starting point. There's no way you're gonna nail it first time.

K needs to be adjusted by hand as the first job you do once engine is started.
