Thread: Lost over 30 whp and over 20 wtq by swapping my stock ecu out (sad)

This is the reason why I went to the same dyno and tuner to avoid any variance in the dyno results. I do feel power loss its not the same dream car that i had it at.

Raising your rev limit is very easy if you already have a daughterboard in the ecu. Just download tunerpro and go to bin change the ecu rev limit and raise it to 8K and its done. Then burn the new bin to a set of chips and it will be done. Your issue was that you were tuned with a safc, which I can't see doing better then a complete custom bin on a ecu.

Goodluck

Ditto to what jonwepa said! If you had the realtime ecu it would be even easier. And if the timing is off, that could answer ALOT of your issue with the hp loss. A wideband, and some consult info (you'd need a consult cable), and a rom burner and you'd be set (with the calum basic ecu)!

Then once you get the car tuned based on the wideband data, you can take it to the dyno and finish up your tuning for hp (but you'll need the burner).. Again, realtime IS the way to go IMO.

Ask calum for a 100% stock sr20de bin, and put that on your chips and just bump up the rev limit. It should be just the same power as with the stock ecu plus safc. I know he has stock bins
