Hi All
I want to learn more about engine/vehicle management and since I'll likely be fitting a bigger engine to the Jimny in the future, I'm looking at fitting a standalone Haltech ECU (flavour yet to be determined). I've already confirmed the M13A Trigger and Home signal configuration is supported in the form of the M16A option in the Haltech ESP software. Further detail can be found
at the Haltech forum.
Since I want to be able swap back to the OEM ECU to drive the car between tinkering sessions and possibly keep the Haltech if I sell the Jimny, I'll be making a patch lead for between the vehicle harness and the Haltech. Given the female plugs (same as OEM ECU) are not readily available I've sourced a spare ECU from Gerryb here, to butcher for the plugs. I've also got the AMP Superseal plugs on the way from DigiKey for the Haltech.
What I still need to work out is the pin-out of the ECU harness. Since Suzuki went to an online manual for the VVT Jimny's I'll likely have to bell out and test every connection.
I plan to post as much detail here as I can gather
If anyone has a link to or copy of the wiring diagram for a VVT Jimny MT ECU. I'd be much obliged. I'll still need to bell and test a lot of it anyway but would be nice to not be going in so blind. I do already have copies of the the latest available manuals that are proving to be of some value, but they're pre-VVT and relate to the 3 plug ECU's not the 4 plug unit my Jimny has.
I'll be farming the actual fuel, timing and VVT mapping etc out to a real tuner with a dyno and I'm hoping to be able to find one in Vic that will let me sit in on the process.
I've also pretty much written off getting the factory immobilizer operational unless I get real keen, sniff the workings and possibly patch in an alternative microprocessor to do the job. Maybe not so difficult now I think about it......
Still need to get my head around the 4wd controller I/O and what that connection actually does. This doesn't scare me a whole lot though either.
All this being said I may very well be biting off more than I can chew, in which case I can always just go the piggyback option and be done with it.
If anyone has any info that may be useful please post away.
Aaaaaand before any naysayers chime in...... I know it's probably (read: definitely) not worth the money or the hassle but I like to learn and there are very few options for fitting an aftermarket ECU to my 3.0L CRTD Colorado and the Jimny will be a whole lot cheaper to fix if I cock anything up...... and cocking something up is very likely
Watch this space......
