Did anyone get the map changed when fitting the throttle body?

Thats because people think they can just fit them and gain power but any drive by wire T/B will need to mapped into the ecu to make it work and idle correctly Thanks for the link

I'm looking into a bigger drive by wire T/B for friend as he said that you guys bore the T/B out and fit a bigger butterfly? I've never been a fan of doing this as it could cause problems etc. Not sure about the 172 or the 182 but have been told that the 197 people bore this one out and fit a...

Porting the inlet so all of the ports are the same size at the mating faces

Re: Ph1 172 Looking forward to seeing the results of these when fitted to your engine.

And it will come back looking like this;)

A Ph1 head ports are as large all the way back to the valves

Now i was told that it was only a little bit bigger but thats massive

A break down of the engine spec would be nice

Ill pm you later to talk about it

Sorry picture is not a clio flywheel that I posted

There are some negatives of having a lightened flywheel As fast as it will rev up it will also drop down the revs as fast when letting off the throttle. Lets say you have a engine with a small power band and a lightened flywheel, you don't want the revs to drop out of its power band

The engine will rev freely i'e faster revving It will feel like you've gained more BHP but you won't have

Thats ok or does it include MOTs with that Ive been to Greece many times and it looks like 95% of cars over there don't look road worthy or had some sort of MOT or what ever they do over there

will do mate

Your not the only one as i want one to cut up and ported the life out of it to see where there limits are

Re: Ph1 172 I'm looking into a few things for next year so i'll keep you posted
