This is great. I have an MY08 with m18a blue plated in Qld. Its Torquey but slow. Watching this space with great interest. Would love a bit more punch

[selaga]

What are the issues with this proposal...

M13 non VVT -> M18 VVT (both manual) using the complete harness transplant from Liana ?

[zukenutter]

Apparently the Jimny ECU also has links to the 4WD system which the Liana ECU will not have. I don't know the finer points but I read this somewhere here.

[selaga]

I thought early Jimmny had all "mechanical" 4wd engagement ?

It does so this may fix the 4wd issue, but I'm pretty sure the immobilizer pinouts are different too. It'll be in here somewhere in squibbys posts. He was talking about a vvt jimny, but regardless it's all going to be the same issues for most of it. And from memory he'd looked into it quite extensively and said it probably could be done, but not worth the hassle.

[selaga]

Complete harness would cure the immobiliser issue with original donor key, transponder reader,etc. ?

So Suzukis run a separate BCM or is it all done in the ECU ?

I think it's all one... Been a while since I've been under my dash

or only vvt to vvt and vice versa?

Anyone?

Thanks

DO a few searches, I think it's been discussed in detail a lot. There was a Jimny on here - O'Mileys Jimny that had non VVT to VVT conversion. Basically you can do it with ECU/Wiring Mods it's not plug and play. The M18 VVT ECU is similar enough to the M13 NON VVT ECU in appearance and pin-outs arrangement that it really tempts you to give it ago.

But the short answer is, that appearances are deceptive and it's actuallty a pain in the butt to convert.

You'll need
a) A very good understanding of what you are doing, Wiring diagrams for donor Vehicle and your Jimny
b) Be competent to re-arrange the pin-outs on the the plug couplers from the Wiring loom to ECU
c) Be competent to wire up a pair from your engine bay VVT Valve back to your ECU
d) You'll need donor ECU's Matching Keys and Immobiliser unit.
e) You'll have to re-arrange the pin-outs to the Plug coupler on the immobiliser unit.

In short, just keep it simple and find a Non-VVT if you already run a non-VVT. e.g. M16 Liana engine? or Pay a professional to do a full aftermarket ECU installation. I got quoted $2000 for this once If I remember rightly.

This is the post I was referring to

Complete Harness would cure the immobiliser issue. The ECU talks to the chip in the key via the ICM (immobiliser control module) attached to the ignition barrel. All three items need to match. (There isn't a seperate BCM to worry about.)

Good point regarding the manual selector on the 4x4, gets you out of that issue.

You need to consider your motives. All the M-series are a bit low on power so the overwhelming motive for many to do a conversion to a larger M-series is the ease of it and the cheapness for the parts since we only really need the bare engine. If we go transplanting the entire loom, keys, immobiliser it's vastly increasing the cost and effort and the scope for problems during installation. There's just not enough motive in it for me. If I was you I'd be looking for a non-vvt 1.6 or non-vvt 1.5 and leep it cheap and simple. The relatively low reward is equal to the low effort you put in.

[jimny_timmy]

Just on the manual 4x4 selection... This could also be avoided with a sierra tcase conversion at the same time. The cutout is already in the floor on all models and just covered with a bolted on plate.

[stockman]

O'malley had a fuck load of problems with his after he bought it. From memory is was left with Suzuki for months on end and even they struggled.
I'm not sure if the fix was permanent or temporary but he pissed it off pretty quickly when he got it back.

[driftke70]

surely you could just delete all the immobilizer stuff at the ecu, they are switches, either need to be paired off or left seperate. Should be fairly obvious looking at the diagrams.
The 3sgte I put in my corolla had all sorts of key sensors and air bag warnings etc but you can seriously just cut it off. Not sure why people are having such issues?

Im looking to go to a vvti 1.8 in my non vvti m13a so ill let you know how it all goes. I cant see why it will be any harder than just swapping loom and ecu. Hooking up switched power from key etc. No different from any other conversion.

You guys have had it easy with the bolt in and plug and play affair that you have seem to have put up a wall to a simple engine conversion.

Taking it to suzuki was a stupid idea, if he wanted his oil changed maybe. Would have just sat in the side of the shed while various mechanics worked up the courage to look at a wiring diagram.

Its a software function within the ECU, no external switches or relays. The immo reads the key code and checks it against the stored codes, if they match it transmits its code to the ECU and if that matches the code inside the ECU then the ECU will run the engine - otherwise its game over. The transmission is encrytped so it can't be simply reproduced.

[driftke70]

then just take the pickup for the key and the key and shorten the wires and chuck them under the dash somewhere.

[driftke70]

also why is using a non vvti 1.8 an option with stock jimny ecu, but all of a suddent the stock jimny ecu becomes an issue when you go to vvti? Surely you could just run the vvti with jimny inlet and exhaust, 1.8 injectors, and just run a switch for vvti. You could pick a few things for your switch for the vvti, id probably run a switch on the dash as I have done in the past. Lumpy idle is pretty much the only draw back of forgetting to switch it.

You should just go ahead and do the swap, make sure you document and photograph the mods and share them here.

Not everyone is an ecu guru so feel free to lead the way.

[driftke70]

I wasnt meaning to be rude just felt like people are doing themselves a disservice for fear of not being able to knock it over in a weekend.
I might make up some looms or something. See what happens.

[driftke70]

Have done a bit more research and have found a company that unlocks ecus so that all you need to do is plug in sensors and wire up switched earth and power.

So get it done and document what's involved. I think this sort of option has been talked about before and cost has been a negative factor.

Already been done. Omiley's jim used this method and stockman pretty much sums it up here:-

Success rate is pretty low so far hence reason you are probably detecting reluctance for anyone to recommend it. Give it a go and post the guide on here if you can get the M18 running on the M18 ECU successfully. Would be awesome to have an update to the thread with how to do this since this is what the vast majority of posts seems to be regarding.

[Davesrt]

Just finished my m18a conversion on my jimny using this guide. It's a huge improvement in power.. No engine lights and running great.. Thanks for the help!!

It seems to have different mapping for 4wd, it determines gear ratio based on VSS and RPM.

[JayKay]

Is there any difference between an manual and a auto M18a ?

Will the jimny flywheel fit on the auto engine I assume they would be the same ( silly question but need to know )

Thanks

[Davesrt]

Hi jaykay, I used an auto m18a engine. The crankshaft bolt pattern matched up exactly to the jimny flywheel..

You ripper, thanks mate.

[tim80z]

I used an m18a from a manual. Either way auto/manual shouldn't matter.

[JayKay]

Ok, guys that have converted I have just completed my conversion with a m18a

And when I hit the key she turns over, but I'm getting the check engine / immobiliser lights.

Also the tachometer and speedo are going haywire.


Any ideas ?

Already swapped the crank sensor from the 1.3

[Davesrt]

Hi jaykay. I'd double check all your earths are on. Check the drivers side there should be the big main earth from the battery and a small I think 12mm size bolt that attaches a little higher than the main earth. Also have a quick check you haven't missed the cam sensor at the rear of the head. But I doubt that'll make the dash jump.

Cheers mate, my dad just rechecked both ( it's at his place ) and they are ok.

I Swapped that sensor out of the 1.3 so it's plugged in.

I'm lost
