My setup thread: https://www.s-chassis.com/forums/ka-t-78/ka-t-s15-gt28r-turbo-setup-complete-list-46294/

I know Nistune is kind of like a standalone tuning unit while Enthalpy is a pre-tune ECU rom service.

I am planning to tune it with Nistune myself, and wondering if I would be ok if I spend about 6 months on reading/researching ECU tuning. I am reading 2 tuning books:

How to Tune and Modify Engine Management Systems by Jeff Hartman
http://www.amazon.com/Modify-Managem.../dp/0760315825

Engine Management: Advanced Tuning by Greg Banish
http://www.amazon.com/Engine-Managem...1745432&sr=1-1

After reading http://www.plmsdevelopments.com/file...ing_basics.pdf. it kinds of make sense.

I just want to learn how to tune my car, and looking for a good typical tune.

Another question for Enthalpy is how good they are. I want to see more details on mapping and timing table. Since they just need to know the injector Size, air Flow Sensor, etc., it seems like they are just some generic tunes. Did they just modify the injection mulitplier (K constant)? Or do they tune more than that? I read many Enthalpy threads, and most people are happy about their tunes, but I want to know more about Enthalpy tunes.

Thanks!

 

just get nistune and go to a dyno and watch someone tune your car for the first time. Nistune uses your stock computer and its just a mod so you can change all the parameters.

Once your car is tuned, you will be able to play around with it a little. I have AEM EMS and its just insane the ammount of knowledge you need just to get the car somewhat tuned.

 

good stuff

tuning is basically trial and error.. you only learn by reading and doing.

 

I have an Enthalpy tune on my POS and there wasn't any issue, well until a vaccum line came off under the lower plenum (not tune related) made 350, from running stupid rich.
