Bleh.... I hate cars

[USDM_OneVia]

Well... after getting most of the drama fixed.... broken oil fitting in the block, cracking a nipple off the heater core.... I got the motor all back in and back together. Go to turn the key.... crank, crank, crank.... nothing. DAMMIT! Now what?!?!?!?

So... tracked down all my wiring, its good. Z32 is wired correctly. Don't know what is going on and call it a day. On the way home, I give Jon a call and see if he has any insight. The only real change I made besides the MAF and injectors was the ECU. The ECU he gave me already had a Z32 chip in it, but he made me another one for the Z32 and 450s. He confirms that the Z32 program works, which I kinda already knew, but we really couldn't figure it out. So I get a little further down the road and he calls back... "Do you have the chip in backwards?" AW CRAP!

So I go back today and check the ECU, yup, chip is in backwards. I reset it and turned the key... crank, crank, crank.... The hell with it... I give up!

On a whim I decide to resplice my stock MAF and plug back in my stock ECU..... crank.. VRROOOM! Whoo hoo! It started, but ran like absolute crap. I expected it to start and I knew it would run badly since it still had the 450s in it and the stock ECU can't drive them.

Well... I whipped out the chipped ECU and put just the Z32 chip back in it to see if it was the whole ECU or just that Z32/450 chip that is bad..... but I left my Z32 wiring diagram at home so I couldn't rewire it back up.

So that is where I am at now. Car starts with my ECU, doesn't start with the Z32/450 ECU. So Jon I know you are reading this, I am either going to need a new chip, or I am going to just "borrow" an SAFC from that black Civic until he finds out I have it.

If I do decide to go the SAFC route, how tough is it to tune it for 450s? I know tuning for the Z32 is just a few easy settings away, but what about tuning it for bigger injectors?

Thanks for the look guys.

I haven't tuned an SAFC, but friends have. I don't think it is hard at all. I know the tuning programs for the eproms is a sinch to change the variable for bigger injectors. I believe it is also simple with the SAFC.

Heres a manual: http://www.apexi-usa.com/produ...s.pdf

I feel your pain. I rebuild my buddies KA last week. Poped her in on the weekend only to find out i messed up the cam timing. I was 180deg out. So out came the motor again to fix that. My moral of the week was : don't do the timing chain when speaking to three people lol. It runs now after an extra day of work.

DUDE you fried my ECU, dude... lol

i think you just ran the power into that chip backwards and fried that chip. ill see what we can do, dont trowaway those eproms either, i need the numbers off them. also we can reprogram them we can get togther thursday and rechip. also if you see this please post the numbers on the chips them self so i know what kind we used we might have used one of our bad chips. i bought 40eproms and non worked.

hey slw... how much could you guys socket my ecu for? I wanted to try making chips but i dont want to try getting that chip out because its like humping the side of the ecu case. I have the socket already too.

ya, the ecu is still good, but your fried the eprom chip, you reversed the polarity on it. I have seen it happen before. Get another chip and you should be good to go.

its best just to take the Ecu to an electronics store that does repair work , they charge relativly nothing to do it.

ps IAN havnt forgotn man, just super busy, ill have him write that programn tonight, ill give him your email, then we just need to pick up some chips thursday to burn with

Jon,

I'm a pack rat, I don't throw stuff away... especially car parts! Hell I still have some Civic stuff that I *might* need one day

I will get those numbers for you. I think the ecu is still good, like I said I will try just the Z32 chip and see if that works. If it does, the ecu is still good then, just the Z32/450 chip is krunked.

What numbers do you need? Where I am looking for them at?

Awesome! Thanks Jon, I need that as soon as you can get it. Thanks again!
