so i went to get my car mapped today, which turned out to be a bust.

the laptop the lad is using refuses to connect to my ecu (altho it does identify it) so he thought with me having an aftermarket headunit it the k-line was at fault. so off i went home to rip my headunit out and see if the k-line was connected, turns out it isnt. ran a test with vagcom and i get k1 and k2 ok and vagcom connects fine?

is there any other reason why his laptop will identify but not connect to my ecu? i know i have a fault with the ccm which says single wire operation??

is it worth hooking up the old radio and taking it back down? the radio k-line needed to be connected for the communications side of things to work?

its 30min there and 30 min back so would rather get this sorted to save both our times

any one who can chime in will be a star!

cheers
 
please tell me this isn't a crappy generic map that some random person plugs in and uploads and lets you get on your way?

if so don't bother going back these can and have been known to do harm to your car. if you want a remap go to a well known mapper with a dyno
 
its a company called evotune, mainly does evo's etc has good reviews everyone i know from cossies to s3's he was just trying to read the ecu toget a dump then rolling road it and obv map it

but his laptoip found the ecu bosch 400? i think or 800 i cant remember which but wouldnt dump the ecu. so he made a phone call and the lad said if its got an after market headunit it might be that. so he plugged in his snapon solus and that fired up but had trouble aswell
 
walk away now

if he cant figure it out he's not going to be that good

its either got revo code or apr or custom code on there already, OR has had a revo trial on it previously, which causes some "readers" problems when identifying the ecu

Fixable, but probably not by him I would guess

stick to guys who specialise in the vag brand and can offer full checking before installing a map, smoke test, fault code checking, before dyno with logging etc.... To Check its fit for mapping

good luck
 
cheers bill

the lad i bought it off was a family man so id be surprised if he got it mapped! lol unless the person before him did. is there anyway to check that its had a trail map or is it for more specialized tools?

a few people on the vagtalk facebook page have said they had a similar problem (albeit on audi's) and they had to have the ecu bench flashed.

have you ever encountered this before bill? as i say vag com works fine i can log etc unisettings wont talk to the ecu either (even with intelligent mode switched off)
 
Had this with mine, I called in to Bill's and it turned out I had Revo software already installed, just needed re-activating, as it had been set back to standard performance. Make sure you take it to someone who knows what they're doing.
 
sounds like a possibility then, ive gotto phone a company in stokesly tomorrow he said he can sort it even if theres revo stuff on there nice to have someone confident and just say yes i can sort it!
 
For the engine its a selector for which ecu map is used, dependant on transmission usually...
 
Yes but revo'd ecus have special coding sometimes, like revo'd tdi's. the coding standard with cruise control n manual trans it would be 00102. With revo n cruise control and manual trans it would be 10102 or 20102.
 
You didn't mention a Revo map file.. Revo do weird and wonderful things with their maps. I have seen what you describe in a 1.9 TDI edc15 file, 2 of the code blocks were untouched and standard though and one had performance values....
 
Yeah I've seen same even have a revo pd150 map. Guessing the petrols are the same
 
It still doesn't get round the fact your lad with a laptop can't tune it. If he was any good which sounds like he isn't, he could of put back on factory sw and retuned on that using correct methods.

If your tuner can't simply refresh back to stock don't let him "tune" your car he's probably using generic files brought cheaply
 
well a little update, took it to a company called big fish tuning in stokesly and he done it straight away, laptop in and read the ecu no problem!

so im now finally mapped but now putting money away for a fmic :D
