a week after my fabia vrs it was remapped and 300 ish miles it had 178bhp 285ft-lb and now 182.1bhp and 300ft-lb and approx 10k miles later im very happy with the celtic tuneing re-map graph is below

at the wheels

and my old meriva vxr which was std before it was stolen :-(

and at the wheels

its intresting to compare a 1.6 turbo petrol graph to a 1.9 TDI one so much more ft-lb and so early in the revs any comments welcome

does anyone else have an AFR graph i could look at or know how to read them ?

I only have the same type of graph as you already have there.

this is my AFR

your graph looks nice and smooth like mine although you have a tiny bit more power lol

On a derv I am not sure what impact AFRs have - Tends to be a petrol turbo tuning thing from memory?

would be nice if some one could give me the technical view of them good bad ect im happy with how it drives just would be nice to here from a boffin lol

AFR looks fine..

Stoich is 14.5 on a diesel so you're running just a tiny bit higher..

Not too smoky i should think like that..

Kev

thankyou for your response its not to smokey at all only at high rpm does it have a puff of the black stuff which i never go into anyway as it just waists fuel past 3,500rpm IMO if i change up then it drops the revs back down into the turbo range so i have full power agian well thats the conclusion i have come to after my nurburgring trip ;-)

going by your graph...

bhp vs. revs.

you want to be changing at 4.5k if you ask me

not the same type of graph but mines before it was re re-mapped

Found my graph yesterday (had lost it) apart from the figures though, it doesn't mean a lot to me :|

Re-map by the same people as Si, at their workshop which is just a short drive up the line.

(The test was done by Celtic Tuning at time of re-map)
