hi guys. Been trying to put an ABF in my mk2 forever now it seems. Got it in and wired up, only problem is no spark. Checked the fuse box to find that the yellow plug with the big red live was loose. Pushed it properly and went to turn it over- nothing. Charged the battery and now can hear the distributor clicking and getting a weak intermitant spark when i earthed a plug. But still not firing. I have a new crank sensor on order as the wire on the current one looks shegged. The engine is a '97 seat lump but the loom and ECU are from an early corrado, which i was told didnt have a transponder unit. Could tryin to use a early loom n ecu be the problem? Any help and advice is appreciated. Cheers. Leon
What's the part number of the ECU? If it ends in AB it's the non-immobilised one, if it's AE it's the later immobilised type.
Right, i see what you mean. doesnt really help. anychance you know any ABF ECU codes i should be looking out for?
not off hand, but if it has a large multi plug and a vacuum nipple then you can be reasonably sure its an abf one!
Oh, hang on... I see the problem, I think. I missed this on your original post. A Corrado ECU would be a KJet or KE Jet one, right? So designed to work with a dizzy with 4 spark windows. I don't think it'll know what to do with a crank sensor either. If you're running the ABF dizzy then that's the wrong type for the ECU. You need to run one setup or the other - either ABF sensors, ECU and Dizzy, airbox and MAF sensor, and eventually a lambda sensor. - or Corrado, sensors, ECU and dizzy, airbox and metering head. Mix and match combinations of the two won't work, or at least not properly. Was the early corrado even a 16v?
Had a look at the ECU and it has a big single plug, with some kinda slide n lock mechanism on it. and a vacum nipple next to it. It's a Siemens unit and the long, big(compared to the others which are a smaller font) number which is 037 906 024 AB. Which as Mike suggests is a ABF unit. So, could the shegged crank sensor be the reason it isnt firing? Picked up the new one on the way to uni today, along with new leads.
yep thats an abf one alright, crank sensor could indeed be the problem deffo worth putting a new one on there. My friends abf didnt start randomly and this was due to the ecu vacuum hose being hacksawed thru by a heat shield!
Cheers for the help mate. Hopefully i can get it running this weekend, need my car back for uni! i'll let you know how i get on with it, might be in need of more assistance.
good luck! I'm doing an abf conversion tomorrow as well, but I'm running it on kr stuffs so non o this messin about
digi3.2 is better then kjet imo. ill try n get neil to put up the torque plot for his, the digi3.2 plot is better
we'll see, I have a nice shiny new metering head for mine which i hope will make all the difference, plus all the right pressure gauges to dial it in like gravy. My mate has an abf on digi as well, hoping to get a roilling road sorted out so we can get back to back results.
I'm hopin to go back to storm, i got mine done back when it was a 2.0 8v on the rollers there so be interesting to see what improvement I've made!
So are you sure it's got all ABF bits? Did anything else come from the corrado? If you post a few pictures of the engine, airbox, dizzy, sensors, then we might be able to spot anything else that doesn't look like ABF.
I'l be in the garage on sat, its not at home. so i'll take plenty pics and post them. I have used the ABF waterpump and alternator, changed the waterpump pulley to a 'flat' pulley as i removed the AC pump. The swtiches are all as the engine came, on the side of the head as well as the three on the oil filter housing.
