Hi all!

I tuned my ECU on my MCS when I had 15% S/C pulley(+shorter belt), Milltek CatBack, K&N 57i Induction kit and Denso Iridium IK22 spark plugs installed.

After that I have fitted GRS intercooler, 40' volt coil pack and Magnecor spark leads.

I'm now going to install 380cc JCW Injectors, should I re-tune the ECU after the injectors are installed or will the ECU cope/adapt?

Advise is appreciatet!

IMHO, chipping a mini isn't worth it, the ECU is really adaptable.
You could reset the ECU to make it learn quicker, but it's not important

If you do reset the ECU make sure you don't drive WOT much as it doesn't learn then, it only learns during closed loop

Thank's

After advise from my local tuner, I will use RR when adjusting ECU map. Just waiting for my Milltek Manfold to arrive before installing injectors and a re-map.
