I took the BLUE Pill. Engine bay painted

quattro v1.0 · Post by **quattro v1.0** » Thu Jul 31, 2008 6:37 am

No pics yet, but the physical aspects of the car were 'completed' Wednesday. All items connected to the engine have had their final fit and they are in place. I built the charge plumbing, installed the header / intake / downpipe / turbo / plumbing / etc. Engine wise I only have to add water and its ready.

I powered up the ECU last night and ran my flash upgrade from IIb to IIc successfully (i think) and sent in a screen shot for the glitch fix. I plugged in the grey harness and confirmed my sensors are workin properly. I need to calibrate the TPS cuz its showing a range of 1% to 7% - no big deal. I loaded the base map from the 'other' thread which should get me up to UrQ 25.

My tach amplifier is on the way from 034 and I will begin buttoning up the interior and electrical between now and Friday. My goal is to turn the key on Saturday. I will have to do the exhaust tie-in and then try and get some miles on it before Thursday when I plan to leave for Colorado in it.

cool, congrats! Hey Sean/Hank you guys going to be around in two weeks? I'll be in your town from Monday the 11th through Wednesday the 13th.

I will be heading home form UrQ25 on either Sunday or Monday depending on the car and how much energy I have left. Would be great to get together once you are down in Vegas as well.

I unfortunatly live in Provo Utah now.... oh and I will be in Portugal that weekend! I need to figure out how to get parts ordered to my hotel room in Lisbon...

That kind of range is probably not going to work out well, that is something is wrong.

I think when we checked this TPS it ended up being a 0-3k ohm - right John?

When I powered up the ECU last night it was connected directly to battery power. After that I ran the flash upgrade and powered it off. I hooked up the input harness and looked at the dashboard to see if my sensors were functioning. I noteced the range of 1% - 7% on the TPS while operating the throttle.

I never changed any settings for the TPS in the ECU I only watched for the numbers to change with the throttle movement.

Im open for any and all suggestions as Im getting down to the wire time-wise.

Hey Mark, I'll be around so if you aren't in town to play and lose all your money and would rather talk audis and put something on the barbeque, I would love to have you over. If Sean gets home by Tuesday, maybe we can fine tune a bit or just try to figure out why it won't run..........aaaah slow.

Sean, You didn't by any chance get it on the digital switch side of the TPS? The analog side if I remember right had the wiper the furthest toward the center with the outside pins being both ends of the pot. I think you are right that we read about 3k though.

quattro v1.0 · Post by **quattro v1.0** » Thu Jul 31, 2008 10:32 pm

I went with the 034 manual suggestion of pins 1-2-3 on the TPS, i will check the part numbers on the two units I have, I believe they are the same and try again

quattro87 · Post by **quattro87** » Fri Aug 01, 2008 12:00 am

I think that you are right in that we decided the 1-2-3 pins were the analog pot, but #2 isn't the wiper. #3 is or the one closest to the center of the connection. It sounds like to me that you may have your signal and VCC swapped. Is your y/rd VCC from pin 20 on terminal #2 on the TPS? If the TPS connector reads 1,2,3,4,5,6 across the terminal then #3 is your wiper and where the purple signal wire from pin 13 would go and y/rd (VCC) from pin #20 would go to the TPS #2 and the black grd from pin#6 would go to TPS #1.

It's way late and if that doesn't get you confused I'll try tomorrow. You aren't the only one frustrated today however. I spent half the day looking for Hanks lugnut key socket so that I could change the track tires off and put street tires back on. Never did find it, so that might be the show stopper.l :frustrated:

note to Hank: nobody will steal 15x6" rims ;o}

My Y/R is pin #1
Pur is pin #2
Blk is pin #3

It might be that Pur / Blk need to be swapped...

I will swap TPS's tomorrow and hope for the best - you KNOW it would kill me to cut up my harness

quattro87 · Post by **quattro87** » Fri Aug 01, 2008 3:45 am

Yea your ends of the pot don't really matter as far as grd and VCC, but the signal has to be on the wiper in order for the voltage divider circuit to work.

We wouldn't want those 15*6's jacked!!

What can't sleep???? Up pretty early aren't you? I know you just wanted to see what working in the garage was like when under 100F!

great, sounds like a plan. I'll PM you my cell phone number and we'll touch base next week?

Well, it's buttoned up tight and full of fluids, and Im almost ready to make fire.

All relayed systems power up with the key, Im going to plug the laptop in and see what everything looks like from there.

There is still the last couple wires for the LC-1 and then try the free-air calibration.

Of course it feels like Im going to forget something, hopefully I will take a break for dinner and they it will be too late to start it for the neighbors. That will give me a good reason to just poke around and look at things as I clean up the garage, I can attack it with a fresh mind in the morning...

Post by **Hank** » Fri Aug 01, 2008 5:59 pm

nah, thats how neighbors understand you a little bit better!!!! although, the sub 90 degree weather of the morning might be nice...

You wont forget anything..... Just double check the timing TDC wise so we dont end up with a valve replacement job on tuesday night... when I say we I mean my dad and you. :-D

Other than that, nothing is relaly going to break.. LC-1 calibrates really easily, and you are off to COlorado my friend..

I think Helios is my favorite Ur-Q color

But they are R compounds Sean!!!!

Hey so did you get the TPS to work?

quattro87 · Post by **quattro87** » Fri Aug 01, 2008 9:40 pm

So tomorrow is the day huh? I will be at work and afterwards I have to go to a wedding....one of my wifes co-worker or something. I would rather be at your place for the fireworks, but better not press my luck. Be sure to post up some results, so that I can at least feel better about being at work. Good work Do you have the dash and interior buttoned up already? I thought that we kind of v-clamped the old exhaust to the new downpipe. There was only about a hole or two the size of quarters showing, so why are you worried about the neighbors....ohhh you get a written complaint about the trees needing to be trimmed and now you are running scared. lol I think it is going to fire right up.

Hank brings up a good point as far as timing goes. Since you pulled the head are you certain the dot at the back of the cam gear lines up with the top of the head, the #1 piston at TDC, and the flywheel mark lined up all at the same time. Bent valves from just turning a new motor over can really kill the mood and remember you have a deadline to meet. :wink: Good luck

I tinkered around a bit tonight after dinner.

I got the LC-1 hooked up and calibrated (not that I know what Im looking for) then swapped the TPS's. The 944T TPS is compatible but two of the pins are swapped. When I put in the AAN TPS everything fell into place. I have all my sensors functioning, the lambda is reading, and the TPS is calibrated.

I had kept an eye on the timing during reassembly and I have TDC at the flywheel and the cam sprocket. As far as I can tell its dead on where it was prior to coming apart. If my counting is right Im 16 teeth before TDC on the VR.

I have yet to mount the throttle cable as of tonight but at least I know what Im going to do with it. As far as a throttle stop - that is going to have to be real creative.

I have to do some mad shopping for an air filter, Im thinkin the Greddy low profile is going to be the one that works best.

Any suggestions about crankcase ventilation on a 20v? I probably should have worried about that earlier but... I know its not quite as bad as the 20v's, can I get away with just an elevated filter or will I need a catch can of some sorts?

off to bed again, an early night for me!

Not positive this will fit, but I cannot se a reason why it wouldn't. This is the breather/ oil cap used on the VW New Beetle, should help you out a bit if you want to go that route:
