Any full ECU maps??

[Maelfyn]

Okay. Anyone got a complete map of the ECU? Car won't start and the temperature gauge needle will not show. It must be related to a wire in the ECU because I think we messed something up installing the safc. We can't figure out what though.

[00CericaRuss]

I'd suggest disconnecting the AFC completely, and putting it to stock... see if it fixes it, then reinstalling the AFC carefully and crossing your fingers

[kaioshin]

Nope, that didn't work either. We tried pulling all the connections and covered everything back up in electrical tape. Still get no temp reading and the still won't start. Could it be that we flooded the engine?

Wow!!! If you put things back to stock and you still haven't fixed anything yet that means you screwed something up majorly. Did you check your ground wire? Even the Maf wire can screw up your start-up. I suggest triple checking all your connections, make sure none of the wires aren't shorting each other out.

sounds like u mighta fried the ECU.. u did disco the battery when doing all the wiring right??

[GTS LAID]

I'm gonna have one up for pinota by the weekend.. my scanners all f*cked up right now... all the pin designations and proper voltages

[Maelfyn]

Oh lordie, not good. We didn't disconnect the negative terminal of the battery. Didn't realize that could cause problems. So... how much is a new ECU~

[Maelfyn]

I have a bad feeling I have a worst case scenario on my hands. If I could find an ECU in a junkyard this might be the cheapest solution. Anyone know how to replace an ECU? I'm guessing it just unscrews and slides into some pins.

If I have no luck with junk yards I might have to get one from Toyota. I think the wire harnesses themselves should be fine, right? Just the computer itself is possibly fubar.

[kaioshin]

Doh... oh well. hopefully I will be able to find an old ECU, not the screwy new one with the deflicted cut-off...

[Maelfyn]

Here are the symptoms:
-Temperature gauge needle does not show. Everything else on the dash is fine.
-The car will not start.

Since something is apparently wrong with the dash it makes me think I messed another wire up somehow. The integrity of all the wires seems fine to me though.

Maelfyn and kaioshin,
Here are two good resources that may help you find an ECU cheaper than at a dealer. Larry told me about these sites recently:

http://www.junkyarddog.com/

http://www.copartfinder.com/

also, if its a GTS ECU.. i might be able to help u out.. let me know ofcourse over email..

[Maelfyn]

Thanks mang. I actually already tried junkyard dog earlier. Still waiting for responses. Here's a question for ya. Are the GT-S and GT ECU the same? I looked at my CPU and his and I see no real differences.

[kaioshin]

Cool.... Thanks man! BTW how's the reground camshaft doing?

[Keyshawn]

Kaioshin,
I decided to send my cams to Crower for development instead of Gude. Brian Crower promised me free Crower performance cams for my assistance, versus the $600+ I was about to pay Gude. The only thing is that I have to wait 4-5 months while Crower develops it for all of us. I AM, however, looking for a junked GT-S intake manifold for Gude to port, so I can see how much hp we can gain from that. Stay tuned, everyone.

Maelfyn,
As far as I know, the GT and GT-S ECU's are different. Be careful and good luck!

[Maelfyn]

I got a few emails from junkyard dog. They said $160 shipped for a tested ECU. Not as bad as I thought it would be. I wonder how much Toyota would charge for one.

id go for the one through junkyarddog then.. not bad... but I dont think the GT and GTS ECU are the same.. cuz the rev limiter is controlled by the ECU.. I wonder how a GTS ECU would work on a GT :)

[Maelfyn]

I see. Man we are really bummin that the car isn't working. Nobody here has ever removed an ECU before? I was wondering how hard it is to take out. I was guessing those phillips screws just come out? I'm not sure. I ain't messing with it anymore :rolleyes:

I have an extra Intake Manifold, but I'm still deciding either to sell it or save it and donate it a company like Skunk2 to make some thing better than stock. BTW- Should I still send in my cams since you are already?

As for Toyota stuff (junkyards) check out taprecyling. They have a website, they show pictures. You can get basically anypart for any toyota.

[Maelfyn]

Holy cow! www.taprecycling.com kicks butt! They have four Celicas.

[Keyshawn]

XskoopX,
I think I've got Crower taken care of with my cams. I'll email Brian Crower again to see if he needs another set. If not, maybe we should work out a deal with another company. Skunk2 makes kick-ass Honda engine parts, but before you donate, we gotta ask if they are serious about making stuff for us. They make aftermarket intake manifolds, too, so your intake mani might be useful to them. Also, Unity112 knows alot of other companies who can potentially help us out. We'll have to see what our options are.

to remove the ECU..

remove batter

remove 3 bolts, 2 on backside and 1 that connects to fuze box cover

unplug all the connector and feed them through the case

pull out ECU case

Ive never tried to get the ECU outta the case so I dont have a clue on that one..

Well judgeing from my experience with mine, and my freinds jerry rigged 5.0's it sounds like you crossed some wires. thats my two cents. i could be wrong though, i think it could very well be the ECU but wouldnt more be wrong with the car and the electronics??

See, I told ya Taprecycling. But the one and only GT-S in their yard has no engine. Hmm, I wonder why?:rolleyes:

Keyshawn:
Don't worry about me sending my cams, as long as they make something out of it. As for the intake mani, Skunk2's intake manifold for the B series motor is a straight replica of the ITR's Manifold. They would have to work from scratch and need a car to work for testing tuning. Luckily, 1: they're only 25 minutes away from me, 2: My crewmate is using his car for their exhaust prototype (FULL-CAT BACK EXHAUST!). And 3rd, I have another car to drive around.
Hopefully, you get what you want. YOU DESERVE IT. With all the work you try to stir the aftermarket, you alteast get yourslef a set of brand new spanking cams!:D

Well, I don't think we crossed any wires, we quadruple checked the wires after the car wouldn't start and everything is taped up with electrical tape and I didn't see any cut wires. The ECU may not be completely fried, just a certain part. Hopefully, I can get my hands on another ECU and find out for sure.

Ahhhh... that's cool. Let us know how that goes. I have a ported intake and exhaust manifold (Larry's old ones) and I am having the throttle body enlarged. Gonna have everything dynoed and tuned hopefully before next year. Gotta get her running first though!
