Tuning 2002 ECO with HP Tuners
Thursday, May 03, 2007 8:52 PM
Hey everyone, so my and a buddy of mine have been doing some tuning.. well mostly him, i only drive.. but before the tune, the car pulled real hard from every gear, and easily saw 8-11psi boost with my Hahn stage 2. At thoswe times, my air fuel ratio was about 14.5 in full boost (lean) to about 15.6 cruising speed. now after our first tune, i have never seen over 6 psi boost and i am getting into the 10.1-10.9 range for Air Fuel ratio. still getting about 15.6 AFR at cruising speeds. any recommendations for a more solid tune? i mean i want it to be safe and all, but i mean i also want to see the full potential of my Turbo kit. thanks in advance

Your tune should have nothing to do with the PSI ouput... check your lines, pipes and wastegate... something is up.

Flash it back to stock and take a look, I bet you it's still at 6 psi.

how do u figure that your air fuel mixture wouldnt have anything to do with your boost? i mean, if your car is running better and putting out more power, its going to creat more boost, simply by the fact that the engine would be running to the best degree it can. if you have an engine which is running really rich, so the mixture isnt burned up as much, it will result in less power, thus creating less boost. and just like i stated eariler, i know for a fact my car was puttin down easily 8-11psi boost before the tune, and immediately after, could not get it even close ot over 6psi....

very unlinkely they are related. boost in most turbo applications is mechanically adjusted. a 6psi wastegate always opens at 6.

How I do I figure?

I figure because boost is controlled by the wastegate, which is mechanical. If the car is "running" better and more efficiently it'll actually make less boost to make more power...

Basically tuning can/will affect how quickly you can/will spool, etc... but it won't affect your maximum potential boost. Somewhere along the way you must have a vaccum leak keeping your boost lower - boost is a measure of resistence. You can't just tune out 5 psi of boost pressure by playing with the VE tables.

Just because the car can make more power it doesn't mean it will make more boost... making the engine more efficient and flow better will help you make more power / psi and give you more potential to make more boost... VE tuning isn't gonna do that in the way you're thinking.

You likely have a leak in the system or something is up with the wastegate. Give it a good look over.

You need to do some reading before starting that car again, or you're going to blow it up.
