ECU and Engine Tuning Reference Guide

[wrxgoose]

you put the FAQ, but didn't answer any of the questions.

i really need to try and find a Tuning for Dummies book

I believe on the ECUTEK tunes, the tuner can set the Redline limit to what you want...from 7500 to 9000. Most people go with 7800 to 8000 RPMs.

thanks soo much! would 8000 be harmful? or is that still safe id like a tad more rev unless its useless to rev it that high?

You begin to lose power at around 7K. It really depends on the application and your goal. I wouldn't recommend it because you're not going to increase performance and are only putting additional stress on the engine system.

EDIT - To expand on application, for instance if you're running a more aggressive timing or cam profile, fuel, or port/bore the engine...obviously that changes the powerband and likely power could be gained above 7k rpms, it just really depends.

sounds good to me

My gt86 does not have cruise control, how would Ibe able to adjust/ operate my launch control?

Good Thread!

On EcuTek you can have your tuner make launch control adjustable via the defrost button.

I've already has several guys ask for this.

Correct. DDPR is still playing it a bit safe on the redline as we don't really know where valve float or oil pump fracture may become issues, but with the Ferrea valvetrain I would be willing to risk 8500 for sure - MAYBE 9K.

Mind you at those revs you are looking at heavily accelerated piston and bore wear on thrust surfaces.

Kook thanks

Hi all,

I'm quite confused on the difference between Ecutek tunes and Unichip tunes. Will Ecutek tunes produce more power? Be more reliable? I don't see how Unichip can be so much cheaper if they are providing the same type of service as the Ecutek tunes. Thanks!!

They are two separate approaches to tuning. There isn't a lot of reliable information on the power output of the Unichip solution yet because it's still rolling out to market. The EcuTek solutions have been around and there is a ton of dyno figures out there. I think both have shown great reliability and power increases. A lot of the cost associated with EcuTek is the license and cable to flash a tune. The tune themselves are pretty cheap. Unichip offers some hardware with unlimited tunes that you can reflash via a $35 USB cable.

I will add some dyno info to this thread. However, from a quick search:

Unichip:

EcuTek:
(I will post) but in the meanwhile look for the top few listed, they have a ton of dynos on here.

[Ingeberger]

Thanks man! I will stay posted to see what info comes out in the near future. I found that dyno chart too and didn't really know what to think of it... Is it stating that you'll get those increases with the injen intake? Are those increases from just a tune? I guess we'll just have to see how this system performs. I'm very excited to see what's in store though .

How does launch control work with an automatic?

Last time I checked it doesn't !
