i am taking a brake from the car as i need to get my head clear so i can solve what ever the engine issue is

Take your time man. You will work it out, you absolutely always do. This build is one nonstop challenge, you are doing something no one has done before and it is amazing.

Thanks it is hard for me to step back and take a break it makes me feel like it is winning and i hate to lose

well i think this dam thing washed down the cylinders and now i have low compression and that kills it starting i am seeing less than 100 psi on the compression test i am going to pour stp right in the cylinders to get a thick oil coating on the walls but i think it is toast

Not having great luck with ABZs

no i am not but i am buying the cheap ones from the yards from around me but there are no low millage engines and i have found that if they are left where water can get in the cylinders it really hurts the walls but this last engine was not it's fault but i washed it down with to much fuel as far as i can tell but it may not be hurt it might have just washed all the oil off the cylinder walls

good news bad news ok it looks like my original Audi V8 has a bad intake valve guide or seal and that was causing all the smoke as i can see oil in #1 intake port and the exhaust port is oily where all the others are not this engine was running when i pulled it from the fiero so it should be fine the engine in the fiero is not building enough compression is my thought as i can only get about 60 pounds unless i pour oil in the cylinder and that does not last for only a few cranks then it is back to 60 so i will pull some heads and get things swapped around and it all should run again

well today i bought a Chevy Vega Cosworth engine I am not really sure why other than i am nuts and just had to have it

Wow that brings back memories..what bellhousing pattern does it have- std Chevy?

------------------
86 SE V6 Auto
65 Tempest 400 CID
2008 G6 GT "Street" Coupe
2005 Buick 3.6 Rendezvous
2001 Olds Silhouette (AKA The Band Van)

not sure due to the starter mounts like a ford and not the small block chevy but i think it still is chevy bolt pattern

reloading the firmware did not make it run so i will have to pull the engine as it must have either jumped timing on the cams or it washed down the cylinders and caused damage so it has low compression and since the compression comes up by putting some oil in the cylinder i think there is bad rings or cylinders

pulled the head off the old engine that i over heated and found this

well i am going to try changing ecu as i was holding the throttle to full throttle and it started firing the injectors when the time before it worked right and didn't fire them at full throttle and i have not changed a dam thing on the ecu tune as far as that is concerned so i bought this from Egypt Sptronic http://www.sptronics.com/ i bought it on ebay it is really inexpensive

well i have the new ECU it cost just over $200 all shipped and runs megasquirt software and firmware

Wow that's very inexpensive, if it works out for you I might use it too.

yes i bought mine on ebay so they charged a bit more and i got the one that can do piggy back they sell one without that option for $160 on there web site plus shipping it took about a week for it to come

I have not been working on the car as i have had allot of work at the shop and i am installing another lift this weekend so i can earn more money for my hobby

tomorrow i am going to start to connect the new computer i hope to have it all ready by the end of Sunday i hope it works and the engine runs right then i can get the car out on the road

yesterday i didn't get to work on the car but today i did and the new ecm is hooking up nice there is more than enough wiring harness length and i like that it uses connectors on the ecm side of the harness that work better than the megasquirt in my opinion and this ecm uses megasquirt software and firmware

tomorrow back at it i am hoping to finish up and every one have a great 4th of July and be safe

Wonder what the length of the Audi V6 engine is, and how much better the shaft angle would be using it? Asking because of the bi-turbo stage III setups that are out there? I know that's not your direction but if someone was to follow your path with that it would be helpful to know.

the v6 you would have zero angle it would be short enough as i have looked at them

Engineman what is the axle angle you are running now?

------------------

ARCHIES JUNK IS FASTER THAN SHAUNNA'S JUNK
12.3 is faster than a 13.2

not sure as i have never really measured it but i would say 10 to 15 degrees

Any progress with this ECU?

I had a problem with the ecu it stopped communicating with the laptop so i had to send it back for a repair i should have it back shortly as they are working on it i am not sure if i did something wrong when i was flashing firmware on it but it did happen right after i re-flashed the firmware

Just curious, what are the other current options for the Audi engine management? Do people utilize the stock one or is it too proprietary/unfriendly for swaps? The drive train is a nice layout for a mid engined car like the Fiero. Wonder if the Quattro 5-6 spds can be used as only front wheel drive?

yes you can use a stock ecu and have it reprogrammed and no on the quattro transmission but you can go with a 5hp19 automatic or there are more choices for standard i just picked the cheapest and i will more than likely blowup the transmission due to more torque than it can handle

Ok, thanks. I saw your earlier posting of manual trans cars. Seems that a manual from an 4.2 would better tolerate a bi turbo 6.

well they have contacted me on the ecu and said they replaced the USB controller so now it connects to the laptop but after running for some time it is shutting down on them they said and they are getting that corrected for me i am glad they seem to be trying to make sure it is a top notch product for me and they are treating me great i have bought other electronics and they have not worked right and you try to get it repaired and it is a pain in the butt so i give them A++++ for the service and i am sure i will give them the same ratting on the product as i am sure it will work great once repaired.

well today i got news of what was wrong with the ECM i bought they said after looking at it it had a defective board oh well just another thing i am starting to wonder if this car will ever see the road i know i am a bit sick of chasing this crap !

well they said they have the new ecu and it Bluetooth is a option so i told them yes i want it at no cost to me

PM sent.

Just bought an '88 GT a few weeks back. stumbled on your thread this morning and it's very impressive. It made me laugh when someone questioned why it's taking so long. Obviously someone who has never done an engine swap, let alone a supercharged Audi V8 into a mid-engine car. Hell, it took me 2 hours just to change the AC belt on mine. Anyway, can't thank you enough for the work you do and the fact that you and your colleagues post all this.

PM sent sourmash and thanks drm101 and there are a bunch of great folks on the forum with allot of talent

i am hoping to have the ecm back next week but i don't really think the engine will run as i think it just has low compression but who knows

ok repaired ecm is o it's way back i should have by the end of next week or the beginning of the week after

today i thought i better check the cam timing as i did put a new belt on before i installed the engine and though maybe i didn't get things tight so maybe it jumped timing but after checking it was all good all the timing marks lined up
