would i need a tune

luigi90210 · 08-15-2013, 03:40 AM

Mods please move if this is in the wrong section

I am sure this has come up before but i would like to get some insight on my specific mods/future mods

right now i am in the market for some test pipes, my current engine mod is a Fujita Replica intake(one for the G37, short ram intake, MAF ID changed from stock 2.34in to 2.5in and the rest of the pipe is 2.75in), I want to get test pipes with O2 Spacers built in

I was wondering if i need a tune to run this combination since the intake changes MAF ID, or if i could keep on stock tune without worrying about running too lean since i am already leaned out from the stock 10:1 AFR to 12.5-12.7:1 AFR(got these numbers via ECU and torque pro for android)

Thanks in advance

Yes, you need to recalibrate the ecu if you want to get the benefit from your mods

To really get your money's worth out of a tune, get all of your mods done first. Otherwise you'll have to go back and get it retuned. I'd also do whatever you're going to do about that intake beforehand. You're probably ok running as is until you get tuned, but running leaner combined with high IATs is asking for detonation.

Chuck, this is true if your tuner does not offer free lifetime updates to your calibration! All of our files come with this as long as you stay within the same type of induction, ie; normal atmo vs forced.

Chuck33079 · 08-15-2013, 08:50 AM

Absolutely. That's a great selling point for your service. That could end up saving hundreds, if not thousands of dollars in the long run.

Thank you. I'll go ahead and relocate filters before getting something like test pipes.

If I can prevent blowing the motor, I will XD

I believe I was PMing you a while back, you're tuning with ECUtek right?

When I'm ready to tune I'll PM you

Stock AFR of 10:1??? What are you talking about? 12.7:1 is not lean. You do not need a tune. Secondly ditch your ebay intake.

Chuck33079 · 08-15-2013, 01:01 PM

Yeah, 10:1 is way off. If that intake is making him run two points leaner than that, what's to say it's not two points leaner than the real stock AFR? That would be leaner than I would be comfortable with.

what is stock AFR then?

i was picking up 10:1 stock at WOT with torque pro for android and its getting that reading right off the ECU

If its higher than that that would mean im running too lean already and would either need a tune or to get rid of the intakes

Chuck33079 · 08-15-2013, 01:57 PM

Don't know offhand, but 10:1 is really rich.

should be in the 11.8- 12.5 range at full load that's the stock target, but we have seen them all over the place in real life
