apexi d jetdro cumming holset tune

[50sentra]

Hey everyone!

Looking for some tuning help!

I have an sr20det with nismo 740's and a holset 35.

Anyone have a similar tune with an apexi unit I could buy a copy of the tune from?

Thanks

Why would you wanna do that? Every engine is different so every tune will be different on different engine.

Buy a FC dataloggit, wideband etc if you dont have..

read this: Apexi PowerFC FAQ (http://paulr33.com/powerfc-faq/powerfc-faq.htm#40a)
If changing 440[cc/min] to aftermarket 600[cc/min]
440 / 600 = 0.73
Enter the value "0.73" for each cylinder.

Bolt-on turbo spec. POWER FC applications assume that the injectors have been upgraded. This is why "1.000" is not entered as the starting data for the injector values.

Injector Lag Time Setting

The POWER FC includes factory vehicle injector data. If you switch to any other type of injector, be sure to perform the calculations below and input the correct values.

Changing the factory 440[cc/min] with 0.78[msec] injector lag time to an aftermarket 600[cc/min] injector with 0.85[msec] injector lag time is:

"Injectors to be used" - "Factory Injectors" = "Correction Value After Changing"

0.85[msec] - 0.78[msec] = 0.07[msec]
set your parameters and tune

or take it to a tuner for a full out tune.

Tuning can be done with hand controller I have done it but it will make you want to punch your eyeballs out.

Curious as to what made you go with Djetro though? Tuning for them no doubt takes much much longer vs Ljetro

Hey guys!

I just want some ones tune so that the car is able to drive onto my trailer. I am aware all cars are different just need the dwell values of the injectors to be close so I have some throttle response. As for the computer L or D jetdro it is what it is. I bought it a long time ago and have to work with what I have. I appreciate the link. With that information I maybe able to set the computer myself! I just was into a time crunch but it maybe worthwhile to change the info myself! Thanks for the help biggamehit!

If all you need is to get the car drivable, all you have to do is set the injectors setting and the car should be drivable. Pig rich but it should be somewhat drivable.

Read this to set your PFC injectors.

I build maps remotely based on your specific mods and setup. I can definitely do one for this setup for the PFC. I sent you a PM too. Thanks

IMO, MAP setups are desirable because they remove the restriction of the air flow meter, do not suffer from stalling issues when using a BOV vented to atmosphere and are not affected by boost leaks. The last point was especially important to someone at a recent drift event who destroyed his FMIC in a crash and was still able to drive home. A MAF car would be stranded, unless the MAF is mounted to the throttle body as a quick fix. (how another guy got his car home)
