I searched on this topic but found very little to help and I was wondering who out there has this ECU reflash from Speed Tuning USA for an S60 2.4t. Can you give me a breif about it telling how it feels, psi, any problems, all the general stuff etc. And i am not planning on doing many more mods at all really, besides a drop in and probably stage zero. I am planning on getting it really soon and just want to make sure its worth it. Thank you.

 

1. STAGE ZERO should be done before the ECU upgrade.

2. ST USA ecu upgrades run rich.

3. I have one for my 1999 s70 awd. Great kick in the pants fun.

4. I went from 5-7PSI stock to 15PSI. Your could be different and he might have some different options for you.

 

thanks for the input, is there anything to help it from running rich or to benefit the engine while running rich? also do you have to kinda ease it in at first and takes some time to fully boost well, or does it work right away? any help works

 

No it will run rich. It is just a fact. You can run Premium gas but that cost some $$$$$. You should run Premium gas with an ECU upgrade anyways. It is tuned for like 91+ gas.
