Hi all!

My first post on this forum.

I tuned 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!

 

With just 380's the ECU should adapt fine, but if you really want the most efficiency and power you will need a tune(not a GIAC), a Jan tune will do the job the best. And if you are looking to upgrade in the future skip the 380's and go to 400's or 440's... that + Jan's tune =

 

Thank's

I'm located i Norway, so I guess a Jan tune is difficult

 

Well, for now it is...he is setting up the means to do remote tunes as well Or you could find a Dimsport(or many other brands) tuner in Europe that is renown for their work and have them go at it:thumbups:

Sorry for not noticing your location.

 

i would dyno the car before you add the injectors and see what the A/F is. just adding a pulley doesn't require injectors.

 

I was thinking that adding 380cc injectors was a smart move to avoid lean fuel and danger for early detonation at high revs. (Better to be safe than sorry!)

 

agokart makes a very good point.
And asbnil- you have the right idea...now just build on that...custom tune

 

I have just spoken with the guy who made my first ECU map. He recommended a new re-map to adjust for bigger injectors.

Thank's

 

if you were happy w/ his first tune - follow his lead.

 

Thank's all

Will use RR when adjusting ECU map. Just waiting for my Milltek Manfold to arrive before installing injectors and a re-map.
