An obituary - (10/17 - All is again right with the world)

Kenny,

Hydra EMS NA : 510-870-5237

Andrew Nam is probably the guy to speak to if you call.

Well, for those of you who follow this thread but weren't at Ron's today...

This wiring is the LAST thing I need to finish. Its for the AVCS. I found some pins for the connectors, after cutting some now-unused pins off of one of the ECU connectors to go with the other pins I got from IA Performance.

I made all the wires up tonight with the 12' of shielded cable I had (two 6' lengths for the 4 wires) and crawled into the footwell to get everything run. Then, after I realized that I probably won't be able to get the wires through the hole in the firewall where the main wiring harness runs, I decided I might not have had enough wire length. I really had no choice, though. Its what I had.

Imagine you spent 2 hours soldering up all the wiring, and getting the shielding set up to a common pin, with heat shrink and nice electrical tape wrap on everything. Then imagine that you might have to redo all that. Yeah. Frustration central.

When I start staring at the engine bay and think about removing the intercooler (AGAIN, for the 3rd time THIS WEEK if I do) to look for more pass-throughs, its time to stop for the night.

There's a reason why there are a lot of holes in the wall in my garage from wrenches being thrown.

Not throwing in the towel when you know you're way past due.

Good luck, sir. and if you don't find a hole, make your own

I cheated. The main wiring harness has a rubber boot around it where it connects to the firewall. I realized that I have some high-temp silicone sealer, so I punched a hole in it and fed the wires through. Had enough wire, routed things nicely (will have to get some split-loom to cover the wires) and they have enough clearance away from the exhaust to not cause me much worry.

Hooked everything up and the car ran like absolute trash once I got rolling. Kept trying to stall out, cam advance angles were totally whack on each side (maximum cam advance in the map is 45*, one side would be at 35* and the other at 60*!). Would idle fine on start-up, but once the cams advanced once it would be all messed up, like it was misfiring. Disconnected the new wires for now until I can figure out what I did wrong. I don't mind farting around as long as I'm not going to hurt anything.

I have gobs of crap routed through that rubber boot for the Hydra, DTEC, and H2O injection. It's the perfect spot as everything dumps right above the ECU kickplate.

Anyway, sorry to hear it, but it'll work out.

Quick update...

I found the issue with the wiring, AVCS now works. But the CEL is flashing really fast. Possible explanations include knock or false misfires because of my lightened stuff. Have yet to find an explanation, and they've blocked NASIOC here at work. Car seems to run ok, though. Logs indicate that AVCS is working as expected. Have yet to give it the spurs since its not tuned for lower octane. Very hard to resist. Will be flashing a "learning" map this evening and going for a drive. Hoping that it will start to pull out timing in problem spots so I can start to tweak things in.

[Alizarin]

Well, any timing changes I put in there don't seem to keep it from dropping out of boost control. I've got one idea left to try before this weekend. If that doesn't work, it looks like a trip up to GA to get it tuned by somebody who knows what they're doing.

Once I can keep the car happy enough to do a full-boost pull, I can tweak things in from there. The hard part is getting it to that point. Seems like that spiffy turbo inlet hose has improved my volumetric efficiency more than I had expected, so it needs even more timing taken out.

Kenny, if I don't see that car out there tomorrow, I will completely consider you the worst engineer ever...

Hungess out.

[WAFlowers]

I think you'll see his car there ... sitting on the sidelines as he drives my S2k!

[Agent]

I sure did...

[Subsonic]

Thanks for a good thread, very juicy. I hope the car and you are doing well?

[Alizarin]

So, for those of you who are playing our home game... Somebody on NASIOC finally hit on a few things that could cause the flashing CEL like I had. One of them was correct.

On the JDM engines, there's a second air temperature sensor, which is cool as heck for logging and stuff, but on my wiring harness, the wires for said sensor appear to be going to the wrong pins on the ECU. This causes the ECU to freak out, since its getting voltage where it does not expect it. Hence, limp mode and the rapidly flashing CEL.

So anyways, its got a "weak" map in it from the tuner in Atlanta. Even so, it still pulled almost 19 PSI on a back road about 10 minutes ago, according to the logs. My boost gauge said 23. I think that needs to be moved somewhere else in the plumbing.

I think you should keep the boost low just to be safe


Glad you finally figured that thing out and it's running to it's potential(almost).

[kickslop]

Awesome news.

Scott (the tuner) said he gave me a lower wastegate duty cycle map so I could do some good pulls and not worry about over boosting. The logs may be indicating some very short duration spiking, but that's something that will be tuned out.
