We have just had a similar problem with our S2 stagea. First I bought a brand new tps as fault code and a mechanic said thats what the problem was. Fitted new tps and no different. Went to different mechanic and I was told it is a fault with the ecu that causes tps problem and can't be fixed. Couldn't find a std ecu to replace (rang about two dozen wreckers around aus.) so we are having a Vi-pec ecu board fitted this week.
I have for sale an Apexi SAFC S1 (blue screen). Full loom, instructions and stand are included. I am making way for a Vi-pec ecu board to fitted this week. $200.00 plus postage.
The tps was getting eratice volts from computer. We sent it away but it coulnd't be fixed. I have been assured Vi-pec will run our S2 Neo tiptronic auto. If not I am going to hurt somebody!!
TPS wasn't problem. ECU stuffed. Vi-pec being fitted next week. I had air flow meter out yesterday to measure up for adaptor so I noted number. I want to keep air box. No. is; 22680 31U00, A36-608, E60, 8X17E.
Wheels & tyres you see in pic $400.00. Some big skids lelt in tyres. Grab the rad. for $ 100.00 (driftn). My new rad. cost $450.00. I'm going a Vi-pec ecu board next week so I have some more bits to part with. An Apexi SAFC with instuctions $200.00 plus post. Also I have a Jaycar Booooost controller, lead, handset and instuctions $175.00 plus post. My Apexi 'Multi Checker' will also be sold if it can't be used beside Vi-pec!! PM me if you would like pics because it is easier for old blokes!!
The rad. i bought was a replacement to suit a stagea and the bonus was it is 25mm compared to std 16mm. It was 'brand new' at $450.00, alu. core. I had to sell my little left finger to pay for it. I have used rad. socks for years now. I took sock out today to see what it had caught. It had a heap of head gasket i had scraped and lost into water jacket plus some machining swarf. It came with rad. Prior post on head gasket story.
I have one in good nic taken out of our wagon a few weeks ago. I replaced with an 1" core one. I bought local so I could see what I was getting and at the time couldn't wait for it to come from Japan.
I have been assured that the Vi-pec will run our S2 with an auto. If not I will not pay for it and I will have to hurt somebody!! Tangles; We decided not to go 2nd hand ecu because no warranty and Vi-pec can be tuned to our mods!!
