wasnt able to upload the picture the first time, looks like youve now seen the picture since sorting out the file.

 

Just need to find a corrado shell to start it all.

 

Anyone got any ideas or clues on how to get esp fitted up?

Just got my second Corrado for next to nothing, admitedly its not in the best condition but for what I need it for it's perfect. Some decent aspects to the car inc working sunroof, ss back box, working engine, pretty much all original too, but that will soon change lol

Yeah the windscreen edge will get sorted but because it's not going to be a run around and is stored under the car port there isnt any rush for it.

Now that mine's nearing completion, I thought I'd have a nose at yours :D I'm loving the satin black work and the blacked intake, very smart!

 

Cracking car!

Thanks Kev, I wanted to go with a style that is neat but subtle (except for the wheels which are a bit of an experiment). Some ideas in the engine bay I must admit may have come from your build.

I think I'm going to paint the top of my slam panel satin black this weekend :D Can't fault the wheels either, they look great! I'd probably have gone with chrome dish bolts myself but Gold does suit your car's paint colour tho!

 

How do you find the performance of the R32 as it currently stands? Other than Pete Griff, I don't think I've actually seen many comments from R32 convertees about the performance! :D I know some of you guys have or had issues with flat spots. How did you get round them? Was it just mapping? I'm just preparing myself for the same issues, lol...

 

I've only driven 2.8 24V Corrados and the torque from idle to 2500ish was epic compared to a 12V. With an R32 it must be pretty savage!

Performance wise Im very happy, but am as you know looking to get more out of her. There is a flat spot around 2k rpm but is more noticeable when in general driving and not "demon" mode. I am wondering if the flat spot is to do with old audi/vw flashfiles as there were upgrades from the dealers to iron out this (prob ampified in the corrado due to the chassis etc), so if I can get the ecm flashfile updated to the new version I can check this theory out. But I dont think it's a problem as such, just a nuisance.

 

Just bought myself a very cheap OBD11 bluetooth adaptor for the Audi and it works really well with the App "Torque", so much so I thought I would see if the corrado also allowed for real time wireless analysis, and yup it does. Still need to play with the app a bit more to take full advantage, but may come in usefull for the stealth rolling road session I'm booked in for in a few weeks. cant wait, but a little aprehensive as Ive never had a car on the rollers before!

 

The RR session is planned as a corrado group even so will be a good chance to see a few familiar faces and to also put names against those Ive not met before.

Yeah it could be that. I guess the only way to be sure would be to hook it up to the old computer on the dyno and watch what the cams, throttle and intake are doing at the rpm the flat spot occurs. If they're all doing what they're supposed to be doing, it's defo going to be a timing / fuelling thing as you say. I think Rob's been through all that with Vince already come to think of it, and nothing out of the ordinary was flagged up. I think this problem affects mainly the MK5 BUB golf engine and the A3 BDB that you and I have. The MK5 ECU is definitely not a favourite among tuners it has to be said!

 

Yeah I'm hoping to get mine mapped well enough for the RR day but if not I'll come up in the daily most likely....

Having some issues with the running of the 24v and could do with some help.

 

Car start and idles fine, and very light throttle up to 2000rpm and is also fine however applying more throttle causes the engine to misfire dramatically enough to not allow revs to hit 3000rpm or above. The misfire almost feel/act like a de-rate and has occasional backfire.

I fitted brand new audi coils x 6 last year and a new water temp sensor too so doubt its these.

 

A scan was carried out after clearing and faults and then again once the engine started up, see attached. Some are expected due to the install but have no idea which are real issues or phantom ones and more importantly which could be causing the problems.

 

Any help would be great.

I asked for it to be set up for 2 lambdas ie just the fronts. But the error codes are still showing so am a bit confused with that. SWICT did say that the rears have been deleted so not sure whats going on tbh.

 

Best way to describe my issue is that the engine feels like its hitting a hard engine speed limiter. But at 2500rpm!!

 

The one that gets me is the crank-cam position correlations P0016 and P0018 which looking on google gives me cause of concern as they all say cam chain stretch!! eek! I'm hoping this is an error code thats generally thrown up like the vr's do when not running.

 

The cam correlation seems to be the only real culprit but I could be miles off. I would change the cam sensors but at £80+ quid from TPS each its not a cheap check and may not fix the issue.

 

I disconnected the cam sensors from the car last night and started the car, didnt start (kind of expected that) then plugged one back in and started the car up, but the running issue was there so tried the other sensor after disconnecting the first sensor and its still the same issue.

 

Even tried with maf disconnected (but cam sensors fitted) and this didnt fix it. But am i right in saying the maf only works at operating temp? I've never noted an engine note change or running issue with this connected or not before this latest fault. plus no errors have come up so doubt this is at fault?

The MAF runs full time mate.

 

What age is your engine? It's only the MK4s that should be seeing chain issues, but here is VW's technical bulletin on it and how to check. KW is german for degrees. - http://www.cfiamerica.com/images/24v/17755.pdf

 

You get a hard limiter at 4000rpm usually when the rear lambdas are playing up, so 2500rpm is an odd one. Have you VAG-COM'd it and seen any lambda activity in banks 1 and 2?

seriousely where the heck do you get these nuggets of gold from!

 

Ive tried loads of times to get vag com to work and have always struggled. So to answer your question, not I havent. Plus I wouldnt know where to begin. I'm away thins weekend but will try and sort out the laptop and cable to get a proper scan etc.

 

You dont fancy meeting up in return for petrol money and some beer tokens do you? lol

Heh, by surfing all day instead of working :lol:

 

Yeah can do that mate. Might not be able to meet up in the corrado though as the V band I had welded on for the cat has snapped off, so basically the exhaust comes out of the downpipe and is F'IN loud!! Can't fix it as I can't weld. What a total pain in the arse.

what spec vband do you need, i may be able to pick one up at work. Why do you think it broke? They are pretty strong.

 

Let me see if i can get the vagcom sorted, if im still struggling, a hand would be good. plus would be great to meet up.

oh forgive me, Ive re read your comment, the band itself gave way and not the clamp. gotcha.

Yeah the band is OK, I don't think the weld penetration was quite deep enough. It was on the end of a 3" flex bellow, so a weak band + movement = snapped off, lol

been a while since Ive updated things but not much ben happening. Mostly been trying to problem solve this running issue but thanks to Kev and Dave I've found the problem and it was the crank sensor

 

Just ordered a new one for around £80 to replace the borrowed sensor from Dave but I took the car out yesterday in the mean time and I must say there was a big grin on my face. Only issue is I forgot how pants the corrado brakes feel compared to modern Audi's lol.

 

Im now confident that the lambdas, cam sensors are correctly plugged in so should all be running as it should (Kev and me found that the sensors werent right) so maybe Ill get a few more hp and mpg? time will tell.

 

need to clean the car up again and sort a few things out to be able to say its all back together properly but at least I can start using it properly again.

Im glad to hear just positives about your car. And you deffo need some bigger brakes. :)

I have some bigger issues with mine as I found cracking on no.1 cylinder wall. Under boost it was destroying plugs.

Cheers Dave, Im away all week so wont have chance to send the sensor back to you until I get back. Sorry about that.

 

Damn, thats bad news! Why do you reckon that was then? Are you saying the crack is causing the plugs to fail under boost or thats a secondary failure

 

Ive already got 312mm disks but the brake feel is naff. On the other Corrado I shall be fitting larger servo assists.

No worries Sam. Keep it as long as you need it or you can have it as a spare one for 25 squid. I dont need it.

I dont know what exactly happened,but I presume that crack was there before. Under boost it shows more then when it was NA. On the opposite side where is the crack is cylinder bore heavily scored. When I did compression test,that one had lower readings then others,but still in tolerance. Under the boost it was loosing pressure and making air fuel ratio lean which was causing detonations.

I will post some pics into my thread.
