computer blown i think

[Ontryl]

hi guys

i just bought myself a ceffy off the boat rb20det AUTO (been here 3 weeks) and it still hasnt got compliance yet

i was trying to hook up the batery on it when i onnected the wrong terminals to the battery

this simply means that i connected positive to negative and negative to positive and then a big spark tried to burn my eyebrows off.

i searched around and replaced all the fuses in the car because the car then wouldnt start and none of the electricals would work. I replaced a blown fuse in the engine bay and now all of the electricals work perfectly

the only problem is that the car wont start now and im afraid that i have blown the computer up. does anyone or has anyone had this problem? the car tries to start and just comes before that point of starting and it doesnt turn over.

i know my mistake and i will probably lick myself really hard when i find out the real consequences of what i have done. the question i got is:

1. What computer do they use? is it exactly the same as the r32gtst because they are the same engine?

2. Could it be anything else?

3. How much is a computer and where can i get one from?

thanks for all yur help people - i need this thing on the road so i can start drifting the thing,

thanks guys

skyline r32 ecu is different because of different electrical accessories try to get onle from just jap kirawee the will have one. Have you cheked the fuel pump fuse ??? give that a try before any thing or pull the fuelm line off and turn the car on reds if there is no fuel comming out thats your problem. Alsochek the plugs to see if they are firing.

Check your relays too I'm sure the fuses should protect these but yeah.. Also make sure there is no alarm/immobilser in there if that's blown up and not working there's a chance it may be still immobilising it.

You may like to open your ECU up maybe theres a fuse in there too ? (just guessing).

i wouldnt recommend anyone opening up their ECU that has just put the battery terminals on back to front.. lol no offence.

u can use any R32 GTST ECU from memory but it will need to be retuned (make sure its an AUTO too obviously).

can u hear the fuel pump?

[Ontryl]

yeah the fuel pump works and the fuse has been replaced?

where is this jap kirawee? is this an importer or somehting?

thanks for your help anyway guys

also try sss automotive girraween (i think).

Before you go buying ECUs for rare-ish cars you should probably pay your local sparky $50 to come down after work if that's a feasible thing ...just to tell you what's wrong.

Question for you - I *think* when you put your car on reds the light on the ECU should come up... can you get your car on reds? Does the light come up?

I did this on my brothers BMW E30 M3... He wasnt impressed.

The fuel pump wouldnt work (Called BavariaCars and they told me how to short the Fuel pump to make it run. But I still was getting a spark when I put a screwdriver into the lead and looked for a spark on the block. Got it towed to sydney (from Newcastle) and it ended up costing about $1500 for bits and labor. I'll track down the invoice later and see what they did, the Haltech ECU is still there so I guess that was unscathed, but some of the ignition controller modules were fried methinks.
