ECUtek mod similiarities...ok to run w/o re-tune?

shoooter_j · 01-11-2005, 04:05 PM

I'm picking up an ECU that's previously tuned with ECUtek for a catless uppipe, 3' dp w/ a high flow cat, and exhaust.

I have the same setup except that I'm using the bosal dp (which retains the stock midpipe w/ cat for those that don't know), which makes me wonder whether it would be safe to run the ECU on my car. Having no gauges yet, I can't monitor anything...I know, its bad

Thanks in advance for any advice boys....

Without gauges you wont know if you are running into a problem, as you seem to realize. Short of an EGT gauge, a knocklick could be of some help in knowing if you are running into trobule. If the only variance in setup is the midpipe, you can get a 3" midpipe with high flow cat from a variety of places (e.g., www.daddysscp.com). The prior setup will flow better than your current setup, which is why you could run into problems. Also depends on how aggressive the original EcuTek tune was.

odds are you'll be ok for a while. the beauty of an ecutek tune is that the factory safeguards are still in place. if you're really not comfortable with driving it till you get re-tuned (assuming you are), see if it has the low / high boost map switching enabled and switch to the low setting.

You should be fine. There will be some learning that the ECU has to do, but it will figure it all out.

Cool - thx for the suggestions and advice guys. I'll probably run the low map to be safe, and try the higher map later

Seems the cheapest solution may be a fabbed 3" midpipe. Then you have an identical setup. I assume you have the midpipe for emissions purposes (or maybe Solo II rules?) but you can just keep it around for that.

Yea I kept the factory mid for emissions and local popo too. Put in the ECU today - can def feel the difference, even with a silencer on the exhaust. Can't wait to pull of the silencer!
