Mitsubishi Mighty Max

[ChargerX3]

[quote=""Jeff V.""]I'm not sure if the pulse coming out of the PTU is the same as the stock Max setup. The Max is wired more or less directly to the output of the coil, which fires 6 times per rotation. If the PTU only outputs a signal every time the #1 coil fires, then that's only once per rotation. It's probably too low to drive the cluster.

I've got some ideas for a workaround, but it's going to require more parts and possibly modding the cluster. I haven't done much work on it because I've got about a hundred other things I need to do first.[/quote]

Yea I've only played around with it at or near idle. I'm sure you have noticed how inaccurate the stock tach is. Mine lagged badly and anything but precise. I've toyed with installing a 3s unit over the top of the existing or maybe cutting it out but I'm not sure how difficult that would be yet. Otherwise a professional aftermarket unit would look great too but I'm afraid it would require too much real estate reaching toward the cowl.

I'm open to ideas though.

[Jeff V.]

You could do something like this with the gauges.

I prefer the sleeper look of the stock cluster. If I can't find a way to make that work, I need to give up on electronics as a hobby.

[ChargerX3]

Yea not bad. I prefer the stock one as well. Just need to tie back in the tach.

Update:

The deed is done! Mivec now works and she is a blast to drive. Have my latest startup vid.

Awesome. Sounds like it's running great.

[Jeff V.]

I'm just dumbfounded at how quickly you got this all together. Nice work.

I want a ride!

Thanks. The tune for now actually runs pretty well. I'll have to tweek it some more for sure though. Lol

Thanks bud. You played a big part in this as well. I'm just excited that this could be done. Driving a MIVEC truck is a lot of fun. Can't wait to 4x4 and start towing things.

Build your own! I know you want to

[Jeff V.]

I don't feel like I did all that much, but I'm glad I could contribute something to it.

So how are you controlling the mivec?

Rpm window switch. You see me grab it in the video. You tie it into your tach signal and then into your device you want to control. Then just set your start and stop rpm for engagement. Super easy to wire up.

I bought this one.

Guess this page deserves an update. I spent the weekend swapping out the rear axle and drums for that of a 97 Montero with discs. Then I got lucky and found another V6 mighty max in the junk yard with the same gears and LSD.

The following vids are the results of this weeks labors.

I might have to come over the hill to see this!

Sure. You come over often?



Also wanted to add that the elevation is 4,500 ft and the crappy shakes you see at higher speeds is due to old tires with some residual flat spots. Like 2004 old. You might also notice the car doesn't pull as hard on the upper end. I think that is due to the long intake runners from regular Monteros. Really need to find a 2003+ Full size intake to get my top end to really open up.

[mjannusch]

Sounds great, and looks like a hell of a lot of fun!

Not too often, but it's not too long of a drive. I'm sure I can convince my wife we need to check out Cabela's and Scheel's again

[ChargerX3]

Yea not far at all. Funny you mention that. I'm at Cabellas right now eating a bison burger.

[stealthee]

I've never been to a Cabella's. I used to go right by one on a weekly basis and stop at a Sheetz basically right next to it to fuel up the truck and myself, but never went in. I don't know how big yours are, but they say this one here you could spend hours in and not see everything.

[Jeff V.]

These are the bolts that hold your upper intake to the lower manifold.

Code: Select all

MF241272	M8x100	qty:2	//Interchanges with many other Mitsu intakes, including all Montero and Montero Sport
MD347641	M8x160	qty:2	//Specific to 3.8 Montero
MD195687	M8x130	qty:3	//Interchanges with all other 97+ Montero and Montero Sport

If you're missing the 160mm bolts, just order them from a dealer. They're around $5. The other ones can be pulled from your current 3.5 manifold.

[ChargerX3]

Thanks Jeff. That helps out a lot. WhAt about the smaller bolts that connect the middle to the upper? Those are all missing.
