Not convinced my Ed30 GIAC Map is as it should be

[Hurdy]

Has the timing belt been done yet?

Could have been fitted out of synch!

[PDT]

Car made 226bhp with stock map on, only had issues when asked to make more power.

Boost values are fine, fuelling is fine, fuel pressure is fine but pulls a blanket -7. Degrees under load and only achieves 170-180% load. But in stock form its fine.

Looking over all of the logs later, will see if I can spot anything, is very strange though!

[MAT ED30]

i had the very same problem a few years ago and it turned out one of the pipe to my forge dv was wrong way around

[PDT]

Im sure Chris will confirm, but car is 100% stock.

I know of a couple of 1.8T's that had the same problem, my brother had to have his fitted 3 times at a local vw specialist, a mate of mine had his done twice a a seat dealers, then eventually paid out for a vw dealers to fit it as it was a tooth out aswell.

It is just that I know of a couple of cars that had been having power issues that both had 1 tooth out on the timing belt like you say and both were fine after.

im really interested in this thread , my car has the exact same issues , in stock form makes spot on power 240 bhp but as soon as my map is on then i can only manage timing of 3 before it starts getting pulled , i have had a new timing belt fitted , wonder if this could be my problem?

[chris s]

Yeah my car is 100% stock other than the GIAC stage 1 map I did have on it.... I replaced the DV a couple of weeks ago, but only to the newer VAG type D model so effectively stock.

Thanks for the comments so far.... as you can imagine I'm really keen to get the car back on a map ASAP

[robdf2]

wheres your car now mate?
have you got any logs you can post up?

i will post mine up later tonight for you.

OK - not sure what is going on as to the best of my knowledge my timing belt has not been changed

what i am still also trying to trace and cure is why my fuel pressure drops then comes back up again see 4520 rpm

Hi Chris,

I have some coilpacks and plugs coming in stock later this week, think it might be worth a try changing them and reflashing a stg1 map, if only for a road test. If they dont help I can swap back to your originals, no charge for the parts.

[chris s]

Hi Dave - I actually have some NGK Iridium plugs at home, but forgot to bring them on Saturday.  I have read on various forums that the plugs have fixed similar problems but with out knowing why or how.

I did have one thought... when you flashed my car with the REVO trail, did you try and adjust the timing settings?
