david-b's 95 Eagle Talon ESi-T Motor Build

[SilvrEclipse]

The map and tps are from the same pin on the ECU

I'll check the MAPs power as well then and see if it's fluctuating there too. Be heading there later today after I help someone move.

Jason where is the accel enrich on/off option? Some reason I'm not seeing it.

[david-b]

Didn't make it to the car yesterday, but got there today. Sadly its raining so couldnt do too much. However, I did get her idling pretty nicely. The TPS was bouncing all over and can't come to a conclusion why. Ran new wires, tried weird jumpers... nothing was working. I reloaded the old map and worked off that to try fresh. After some work, car is idling pretty good. Little rough at times. It does run extremely lean at times and early it killed the motor a couple times. Not sure why the AFR is all over the place though.

Here's the MS log: http://www.dsharp-design.com/1129Log.xls

Just to show people since they all can't see my logs, this is what idle is looking like. Pulse width is still bouncy.

This may sound ignorant but is it possible that the TPS is bad?

[david-b]

I tried a spare TPS that I have and was getting the exact same results as the current one. The SAFC used to read the same thing so I bought a replacement to fix it. Didn't change anything. Both sensors are within spec also.

[david-b]

New log. Jason, I sent it to you.


Today I made some adjustments to MS to try to get the TPS to stop bouncing around. Sadly, not much helped out. It is a little better. I then tried running a new ground wire from MS at the harness straight to the ground on MS. I did it a little half-ass (the Dave way) but it actually seemed to get a little better signal. I'm trying to find some shielded wire somewhere (no place sells it around here) and going to run new wires to the ground and signal wire of the TPS. Read on numerous places that should help.

And looks like the oil return line sprung a leak from the fitting... a brand new fitting. WTF. Was too dark to play with it though tonight... and cold.

This is aggrevating. Each time I think it's ready to drive... something goes wrong.

Definitely going to run that wire.

Remember to load that other map. Your going to be super lean when it is finally fixed and the accel stops feeding your motor. I know i have told you this a thousand times already but I dont want you to forget.

[david-b]

I got your email, it makes sense. I'm going to reload the original VE Table that you sent me next time I go out there. Then I'll make the changes and wire up the TPS again.

For anyone else who still reads this... it looks like I didn't fully hook up the TPS properly so going to run the proper wires and have it fully running off of MS.

I don't have internet at home anymore so couldn't post...

I GOT TO DRIVE HER YESTERDAY!!!

After a crappy Saturday of not getting the car to start at all, I got her started yesterday. Turns out the Pulse Width during start up at 20*-40* wasn't enough. So after I bumped that up, got her started. Stupid Chicago weather. I hooked up the 5v ref wire to the TPS sensor and adjusted one setting in MS that cleans up the noise. After some trial and error, she idles perfectly. The car is running rich at idle, so the AFR was at ~12.5, but will pull some fuel there and lower the afr a little. Looked at what MSLV recommends and it pulls out quite a bit it looks like at idle. Will try that next time I get to the garage.

Fixed oil return line off turbo that was leaking; loose fitting. Looks like just a very small coolant leak from the heater hose but other than that it looks like no leaks.

I cut the hood while the car was warming up good. Unlike Jason, I didn't have to pound the top of my manifold. Made 2 cuts on the braces on the inside of the hood and she closes perfectly.



Perfect fit


After that, I pulled the WG spring so the turbo wouldn't build boost and took it for a drive. Car feels good. Was running lean when I floored the gas, I'm thinking from the WG bypassing the O2, but we'll see once I put the spring back in. That clutch/flywheel feels great. Kept almost killing it off the line, and the rpms drop very quickly between shifts, but it's great. Only time car didn't lean out that bad while nearly flooring it was in 1st gear, and she had some pickup to her. Drove 8 blocks, logged ~85% of it. My dad drove behind me just to make sure I didn't break down or anything and he said it sounds great (of course was loud because of the WG dump) but he liked it.

Random inside shot. Have to clean it up a lot still and rehide MS and the cables.


Then finished mounting the bumper and cleaning up some other stuff and the garage. Was hoping to do some more driving all this week to get the break in done, but it snowed, and have another 2 snow storms on their way, so who knows when the car will leave the garage again



And lastly, my Grand Am is going to the shop. Compression test showed: 120, 25, 0, 0. I'm getting a discount at my old shop and just having them take care of it. I don't have time or space to do a tear down again sadly, but I need the Grand Am asap. Getting towed to the shop this week.

Dude, thats awesome that you got to drive it. And what clutch are you running? ACT?

[david-b]

Running a full Fidanza setup. I have to find which one I'm running exactly again... I believe it's the 4.3 6-puck and then the 8lb flywheel.

[ned032002]

That's awesome how much you've gotten done in the last couple weeks. That's kewl you made the hood work with a little modification. BTW, car looks badass staring into the camera.

[SilvrEclipse]

Glad its finally running man. I cant believe you got the hood to shut without denting the manifold. That wreck must have lifted the front support a little to give you some more clearence. Or maybe the hood pins allow for more clearence, I had to push mine down till the latch would catch.

Yea that sounds right. I have the 3.2 sprung 4 puck in my Spyder, with the 8pound fly.
