can anyone help?

i am a new member and have had my vrs remapped by red dot racing to 196 bhp and 202 ft lb. (car was totaly standard)

after about 6 hr of drive time i had a fault on the car on startup.

i did as instructed bey the tech at reddot and disconnected the -ve. this seemed to sort the fault light.

again around 5-6 hr running time, on a cold start the light reappeared.

I then purchesed the cable and VAG com software to see what the fault was and clear it.

it was the mapped engine temp

this fault kept comming back so i took it to skoda for a service and to try sort the prob

they couldnt do any thing as there was no probs with any of the parts.

so i took the car back to reddot and they lowered some of the peramitters. once again 2 days after on a cold start the fault re appeared so i drove 500 mile again to have standard map put back on

the car ran like new and it was ace apart from not having enough power.

friday jus gone i went back again to get another map put on. this one felt not much diff from standard but had a bit more torque and was nice and smooth. the fuel economy was ace too on the drive back to haverfordwest.

on the way i stopped at cardiff for a few hr and went to start the car and all she would do is turn over.

these are the results or the engine scan:

1st Thing I woud edit out your VIN number on that post

I would try here http://www.briskoda.net/forums/introduce-yourself-first-time-visitors-say-hello-here/octavia-vrs/39428/?highlight=16985

Then http://www.briskoda.net/forums/diagnostics-vag-com/help-these-fault-codes/85631/

Just try searching those codes like I have

cheers

take it to a decent company, someone like Jabba, OK it costs more but you will get it done properly, also they will be getting 220 ish bhp out of it. Sorry but its another case of doing it on the cheap & getting your fingers burnt. If your ECU is fooked a new one is I believe about £600, if you buy second hand you will need someone to burn your security codes onto it, you cant just fit one from another car. Its located behind the wiper blades, remove the wipers & then the black plastic panel behid them & you will find it around cenral in the car.

Got to agree with Stuart - 192 bhp is far less than I'd expect from a remap. Pre first remap my stock vRS was putting out 188bhp on the rolling road. After the remap (by Star Performance) it was up to 216 bhp.

A replacement ECU on exchange is around £870........... I had mine replaced 12 months ago:mad:

As Stuart has said a quality re-map from Jabba will be well worth it in the long run, even if it's just the generic map for £375ish.

If you keep the car a few years you'll make the money back with the extra fuel economy you'll be getting!!

Hi, this might be short notice for you, but JBS Autodesign @ Chesterfield have got a 2 for 1 offer available sat 20th Oct on the Custom Code phase1 generic remap. If you can find someone else, either a friend or somebody on the forum to have it done as well, it will work out at about £223 each all in.:eek: Thats saving a few pennies & you are gettinga reputable remap. Either that or you might be able to get a price match else where:rofl:

thanks all for the info

does this mean I dont need a new ECU?

No, read the post above yours.

can the skoda mechanics get the car back on the road by using the tools they have in there skoda workshop or does it need more sufisticated equipment?

tis just the griffin mills garage are taking there time and I dont know whats happening as they keep saying they working on it.

has anyone had any experience with griffin mills near cardiff?

Yes I have not the best out there but better than white dove by far

billy, when did you get your car mapped by red dot racing ... is the same company that's based in watford that might have done my map?

im gonna pm you my mobile number please give me a call later tonight if you can as i'd like to discuss this issue with you

remap was back in may on a friday.

by the sun the light came on.

it is so hard to get in touch with the guy who did the map and he doesnt reply to emails either. well not recently.

at first they were polite and friendly even now they were friendly but i am very ****ed at the latest problem and i really think he did it on purpose

in may ... hmmm i think i saw your car, i have a silver octavia and i think he was doing your map before he did mine. interesting.

lol

i remember you parked behind the gate.

he mentioned something about tryin a new map on my car and see how it goes to one of his workmates. dont think he knew I was listenin.

car all sorted

cost £150 for the guy at total tuning near cardiff to sort

he knew what he was doin.

cheers

Told you didn't I he's good :thumbup:

Pleased to hear your all running fine again, any idea what he needed to do to get it going? Cheaper than a new ECU anyway!

Is the car back to standard now or running a new remap?

back to standard coz i cant be bothered runnin round if it doesnt work properly. lol

the guy jus re flashed the correct up to date data on to the ECU and fiddled wi VAG com to reacuaint it wi the car, or somethin along thoes lines.

Must say thanks to all who gave me advice on what the prob was and who could sort it.

Just noticed this post.

I know its resolved now, but the checksum fault log is 100% an mapping error. When a re-map is carried out, checksumms must be calculated correctly and accurately as the data is altered in the memory

cheers for that one mate

do you reacon it was done on purpose?

billy

cheers for that one mate

do you reacon it was done on purpose?

billy

TBH I can't see a mapping company ballsing up your car on purpose

I doubt very much it was on purpose, its usually just a lack of knowledge or mistake

I hope so

jus dint get the impression they like me as i been back 3 times to get it sorted but with no joy

has anyone had any problems with getting a fabia vrs remapped at red dot?

i have heard several good reports and the price is a bargain but reading this makes me dubious
