Car adapt after ECU Tune?
Question for you guys. I just bought a used tuned ecu. The guy i bought it from said it was tuned by viva performance with rica program. I installed it tonight and took it for a drive. Couldnt honestly tell a difference. I only drove it maybe 3 miles total but felt stock. I even turned my mbc all the way down and didnt boost over 12. Do i need to reset the car after installing this or did i get a dud. He said it takes a little while for the car to adapt to the ECU. What do you guys say. Im ready to file a paypal claim on this guy.

doesn't matter what ecu you have in it, if you have a mbc in, it's going to boost to whatever that's set at.
And the tune might be set for 12 psi. Stage 1 tunes are usually set around there. I'm currently looking for a stage 3 tune and from what I've read, RICA tunes are tuned pretty conservatively.

Do you not have a boost gauge to see what your boost is at? Installing a boost gauge would be the first thing I'd do right after removing the MBC. Also, what year is your car? In my '97 850R the wastegate settings were all off and caused some low boost issues...

Amen to that. If you have a boost gauge and turn up your boost past 15psi you should hit fuel cut off. A dead sign of tuned or not. If you get past that point then you have something. Curious, what boost were you set to before the ECU? (probably a mute Q without a gauge).

I have a boost gauge installed. Thats why i said i never boost past 12 psi max. When i took the MBC out and ran the factory one, it would only boost to around 5 or 6 psi so i highly doubt this is a rica ecu. Like i said, it didnt feel like anything special or any tune. Felt stock.
As far as boost before, i had turned the MBC down to like 3 psi for fuel economy to see how much it helped or didnt help. Before that i was running 10 psi on my stock ecu. I eliminated the MBC so i know thats not the problem. Maybe my wastegate is out of adjustment but the MBC should take care of that.

i did and could boost past 11-12 psi so something is up with this ecu. i talked to the guy to give me a refund. he said he thought his tranny was going out but its obvious his tranny is fine and this ecu is his problem
