going to dyno tune my n/a sunfire
Thursday, June 22, 2006 12:00 PM
well i got my hp tuners today and tomorrow i'm gonna take it to school and see fi my engine performance instructor will dyno tune my car. our dyno is supposed to be 1 of 2 (in the country) top of the line mustang dyno's. this instructor (supposedly rated by the industry) is one of the best driveability techs there is on the eastside of the mississippi. so might take me a copuple days. i'll try to get a before and after dyno and i will let u guys know how it goes. my mods are as follows:

CAI
header --->2.25'' exh. all the way back
motor mounts
tranny mounts
bored out TB
underdrive pulley
ported intake manifold

hopefully i'll pick up a few hp with the tune. goign to tune it n/a while i wait for rest of monry for a turbo then tune the car again.

unless you have a wideband installed on your car it will be hard to know how rich or lean the car is, narrowband dont cut it, you can still adjust spark advance though

It would be almost pointless to have a dyno without a wideband O2 sensor.

Tailpipe sniffers are not accurate esp on cat - equiped cars

i'm gonna have to wait till HP tuners gets back to me bc i was talking to shifted and i couldnt egit my parameters at all. shifted said that they didnt have my calibration but will be able to tune it when they get back to me.

wheel to wheel powertain http://www.w2wpowertrain.com/ has like 2 or 3 of them. My friend gothis car dyno tuned there. BTW, the mustang dynos usualy read 40% LESS HP than a dynojet or ones like it. Then again, they're really accurate and cost 200,000 bux.

That is bull. The instructor doesnt want you to blow the engine, he may be held liable for allowing you to do it.

Its not bull

ECU's are designed to meet OBD-II and EPA emissions standards. If you start changing items on the ECU, the vehicle is no longer street legal, and he can't knowingly change those things if you intend to use it on the street.

Why dont you tell your instructor that you want to do it for the learning experience, and after he tunes it in the shop you say quote "I promise to return it to stock tune while driving on the streets and only using your tune at the track and cough cough, upload the tune to the internet so all my buddies on jbody.org can endulge themselves in the fruits of his labor." Or something along those lines.

shifted is right, hell even putting a exhaust on your car is "illegal" according to a cop who said my old stuff "looked" loud while parked.

That cop must have been a fricken no-balls rookie. Tell him to look on the net and see how many exhaust systems he can find that are DOT approved, I'll bet he stops at triple digits.
