Juan - for example - I regularly drive with one of my friends who has an E46 M3 - before the ECU and J's mods, he would pull past me at speeds over 90-100 no problem. After the parts were installed, he is not able to pass me from a 40mph roll. We even get into silly speeds but he only just edges me.

now you need a shorter final gear and you would pull away from the M3, I have done it lot of time but with a turbo or SC

I think to buy J's ECU direct from J's Racing in Japan.
I'm worry about the immobiliser CEL on with J's ECU.
And can I disable Air pump?
How much did you pay for J's ECU?
Do they accept stock US spec ECU?
Plz answer me!!! Thx

Finally, I got the J's ECU from japan.
-V-tec point 5,000rpm
-Rev cut 9,200rpm
-Disable Air pump
But, CEL came on at cold start and the code was P0411.
I've tried both way with/without Air pump system.
Any idea? amuse boy~
