Hey Guys,
If I increase my spark +2 inthe 0-2000 + 1 in 2000-4000 + 1 in 4000-8000 will I be getting more power. Should I incease the a/f or just leave it at 0
Thanks

Thatis impossible to answer on a forum withwhat information you just gave. Sorry, but from your question, it sounds like someone else should be doing your tuning for you.

 

Ah, I now see you have a Brenspeed 93 tune. My advice, don't screw with it, especially b/f talking with Brent.

 

i respect the fact that you want to try and
get a little more power out of your engine. i
do however, have to recommend that you take
your car to a shop with a dynomometer and get a custom
tune. why risk your engine for 5-10hp.

also, welcome

no offense....amateurs should not try to tune there car....you post a thread like this and someone tells you to increase it 4 or something and you do...the next day you come back and post "my car went boom" and wonder why. With so many good vendors (B amachips, VMP, Brenspeed, EVO etc) there is no reason to try and do a tune yourself or even modify their tunes. They have put tons of research into the tunes they send us and I am pretty sure you arent going to improve an noticeable amount without being on a dyno measuring the a/f ratio.

 

^^^ + again

These cars get pretty complicated. The main factors involved in tuning are the injector slopes, mass air transfer functions, timing, and the spark advance. All have to be in sync or bad things can happen.

If it was a matter of simply 'adding' - then we'd all give our cars 40º of timing and run strong. Just doesn't work out that way.

Timing is the secret to HP and many factors have to be adjusted and considered when adding timing.

Unless you are a professional tuner with experience on these particular cars, I would not mess with anything in the tune yourself.
