Original Toyota ECU and Immobilizer / Transponder

[Big D]

Hi to All

I need some help from the conversion specialists and the technical members. Actually Anybody!

I did a 2.7 3rz conversion on my SFA, and wired up the original OEM ECU. Now the vehicle starts for about a second and then Dies. I have the problem down to the key transponder and Immobilizer. I dont have those, and need to bypass them. I have googled the last few days, spoken to some of the big names in the industry, and they are not willing to help or even try. I know its their bread and butter, but I will keep it confidential and even pay for the service.

Please I need any info you have. The ECU has two wires that connect with the immobilizer / unit. Wires are marked IMO and IMI. Immo Out and in respectively.

Please send me a PM as I dont think such security info should be on a Public Forum.

Thanks

I think your best bet is to get a matching transponder & key from a scrapyard & wire it in.
Keep your original key setup; use the 3RZ key as a hidden security switch.

Thanks Stef, I did think about that, maybe as a last resort

Ideally I would like to bypass the whole thing.

Easiest would be to fit an aftermarket ECU and cheapest

Jan, I am very close to doing that. I would prefer the OEM system, for reliability, etc. Will give it another go this weekend, maybe I missed a wire or something, if I cant get it running, then I will go Aftermarket. Ran Dictator previously, but might do a spitronics now..

The new Spitronics are apparently very nice and more configurable than the Dicktator; whether that helps with performance on a standard motor is a debate on it's own I suppose

Don't think one can just bypass that immobiliser bit...I suspect the IMO/IMI connections are for data and the ECU will expect data coming in. Compare the costs of the original immobiliser vs a new Spitronics & go from there

This is what we have done with a 3l d4d conversion that we have done on a sfa and it worked out well . Have spend hours looking for a way around the coded key but no luck.
