Advice on map

[wallsjay]

I have just fitted an intercooler to my non intercooled votech charger i will be gettin it remapped by rapid as soon as i can get there. I was just wondering how much change will it have made. is the car safe to drive the 60ish miles to get to rapid

I do have efi live so what PD's should i monitor to make sure i am not completly f***ing my engine up


Cheers

The car will be as safe as it was before during normal driving. Just dont be putting your foot down too hard.

I can't see that making enough difference to throw your fuelling off and do any damage. I'm sure Mark would be happy to confirm his views.

yeh i did mean to call mark today but work took over he did say the other week it would be fine at slow crusing speed he did say listen for knock but am unsure i know what it sounds like

Anyadvise on what to monitor via EFI

Cheers

Is any change needed at all...?

Surely the only difference is that you inlet temps will be lower (all still within range of your existing map)

Then you want to monitor knock. Have a look at the PIDs for knock retard.

i will be changing it anyway as i have fitted it to up the boost

how did u go with ur wheel bearing

Correct in theory. Only issue might be that temps never got very low during intial mapping so that area of the tune/map wasnt checked/changed.
That being said lower temps should indicate less chance of knock, though like I say it depends if it was outside the original parameters that now need changing.

Knock on efilive is usually GM.KR or similar. KNKRET is another one. The discription is pretty clear anyway, if you load the default pids in the scan tool knock is in there. You can set it to sound an audible alarm if it hears knock. But as mentioned as long as you dont hammer it you should be fine. (ie) keep out of PE mode

wheel bearin went well actually took the rear arm off and pressed it out at a mates shop

Ringarm i am worried as all intercoolers produce pressure drop so will be less air in the mixture

Cheers again gents

But its denser because its cooler!? Question is how many grams of air are there before fitting and after in the cylinder?

It should perform the same as the non intercooled on a icy cold morning at part throttle etc. If its going to restrict your intake because it will draw a vacuum then whats the point of it except to drop temps a tad? Surely you can get an intercooler that hardly drops any pressure? Perhaps you need a bigger one?

[wallsjay]

i not sure about it drawing a vacum all ontercoolers produce preasure drop i can go any bigger its huge i am having a custom front bar thats mounted behind the bumper as its so big its spec stats it will only loose .5 psi so shouldnt be to bad just me worrying i think

[J. J.]

Surely an intercooler just keeps the air passing through the intake at the same temperature (or nearly so) as when the car starts up, i.e. no warming up through the manifold as the engine bay and engine etc warms up? That as I understood it anyway.

Take it easy, should be OK. If it knocks PCM should pull timing anyway. Check your AFR on the V2 with your wideband.
