Gen 2 Montero / Re: Gen2.5 EcuFlash Definition File

So a XML file does exist but it is not ODBII

XML does exist for the 98-2000 3.5 someone in AU made one a while back for super charger build. I messaged him to see if he would send it to me

97 ecu’s are not flashable. 98-2000 full size Monteros are as well as 98-99 sports. You can download your roms via tactrix and ecu flash burg without an xml they will do you no good. Jester builds the chrome ecu’s but he doesn’t currently have an xml for Monteros. There are only a couple people who would know how to do so and are the ones who reverse engineered the 3s’s.

For the time being you can get the 3s xml and rom and tune from there. Don’t expect to flash your old monti rom back on if you do. Also you won’t have knock sensor so either buy a wideband or buy a chrome unit.

That's good to know, hope he returns your message.

I can assure you that 97-2000 trucks do no have a knock sensor.. The chip does not even exist on the ECU board for it.

Strangely, Rockauto lists a knock sensor for my truck.  Now, i know Rockauto =! Mitsubishi, but historically they've been pretty good about that for me. 

I'd be worried about knock sensor if i was going for power, but i'm not.  I have det cans anyways i suppose.

Real issue with gen 2.5 trucks is the lack of knock sensor, you can tune them but if you go too far the ECU will let the motor ping it's self to death

Ok...i personally know John from Jestr Tuning.

Sounds good...looking forward to seeing if the Gen 2.5 Ecus can be tuned. I am sure a couple extra HP can be squeezed with some talented tuning.

No Adam from Chrome ECU. His ECU's are known as jesters (pretty sure that his forum handle)

So maybe I can shed some light on this.  Since I have been working with Jester to move forward the montero ECU project.  He will have 98-2000 PNP ECU shortly.

Are you referring to John from Jestr tuning?

It won't.. The 97 and 98-2000 Montero Chrome ECU's are ready. Next step is setting up the base tunes and start up roms.

It's from Vince, he has a Gen 3 3.5 SOHC. Those do have a knock sensor, was wondering how that would roll on my '99 as well.

So maybe I can shed some light on this.  Since I have been working with Jester to move forward the montero ECU project.  He will have 98-2000 PNP ECU shortly. So the deal here is you should get a 2.0 tactrix and download your rom and work from that. The reason here is that there variations in the ROM files depending on what ECU your truck has. International / Federal / CA trucks have different rom files. Is you truck a CA or Fed rig? Does it have EGR / EVAP and how many 02's?

 I don't think you will find a cheaper / easier standalone for the truck than the Montero (version of the chrome ecu) considering the one for the Montero just plugs in and uses all the factory sensors and wiring harness.

From what i understand, definition files are married pretty closely to ECUs, so you don't want to mix 'n' match.  I will try to look at some pinouts this week to see how close it is. That file could work for us IF we can use a 2002 ecu.  Otherwise, i/we need the appropriate gen2.5 definition file. 

Bear with me, i'm trying to put myself through a crash course with this stuff.  If i have to swap to an expensive Jester-chipped Chrome ecu to do this, then i'd just as soon run it on an actual standalone for the same price or less.  But ideally since my current plan is to just toss a non-MIVEC 6g75 at it, if i can get a way to put the appropriate maps on my existing 98 ecu and call it good, i don't care about knock or any of that jazz.  I just need it to run safely and no throw a CEL for missing emissions.  Max power is not a concern.

mate a kia surge tank to a mitsu manifold. just needs a bit of welding and tapping.

So glad I found this thread. I'm actually going through the same process my heads are at the shop. How are your butterfly valves looking, any play in the shaft. Mine is all over the place trying to figure out a cost effective solution.

Gen 2 Montero / Re: Worth swapping from 4.65 to 4.90 with 33"'s?

« on: March 21, 2018, 10:21:16 AM »

If you check ebay out you can get whole locked rear 4.63 as low as 270 bucks plus shipping (freight is fairly cheap) even front pumpkins can be found for 100-150. I know one of the members was selling a locked 3rd and everything you need to convert your 2000 truck to locked 4.27.

The mountain passes are brutal for my Montero in CO, 33's with 4.27, fully loaded with RTT. Even with turning overdrive off and trying to keep RPMs high the truck still starts to get warm. I desperately want to swap to 4.90's, but do I first have to source a locking rear setup from a 2.5, or can I use a 4.63 locking rear and then swap gears into that? So many parts to source!

I know but swapping the ring gear on 3rd that is already out is a relatively small cost in relation to the rest of the project in terms of labor and cost. He would still have to source the 4.63 / 4.90 parts either way.

I think he means that he can just slap in junkyard parts and go because the 4.90's require a gear setup to transfer into a locking 3rd where the 4.63's can be had with a locker already installed.

You will also need a Timing belt pulley, updated crank bolt and washer. The Cometic gaskets are MLS vs graphite. New head bolts should always be used. As for the water pump the AISIN is as good as the OEM mitsu, but you would need to check with Ninja what is the exact part number. They generally stock stuff for FWD cars not the Montero even though some parts like the TB / Tensioner and most gaskets/  seals are the same.

Not following here, the 4.63 swap will be about the same as the 4.90. 5.29 is the expensive one

I'm also running 33's on a Gen 2.5 Winter, but with stock 4.27's. We plan to relocate to CO, but in the meantime we do annual trips up to explore the backcountry. I'm planning on going with 4.63's when I upgrade my gears mostly due to the cost of 4.90's for those of us with factory air lockers.

Gen 2 Montero / Re: How to burp/bleed gen 2 cooling system?

« on: March 17, 2018, 11:23:01 PM »

It takes a couple of tries. Use the two bleeder bolts on the water outlet. You can see one of them have a yellow sticker with some writing next to it. If your truck has a body lift it make require a drive or two. Also make sure that the rubber hose for the over flow is there and working  (inside the bottle to the cap)

Drained and refilled my cooling system earlier today. (New, OEM tstat and overflow bottle after running distilled water and a bottle of CLR for three weeks to clear out the rust water I'd been running since last summer.)

Parked on a slight incline in driveway, nose up.

Filled radiator, started engine with radiator cap off.

Heater on full blast, mix of idle and hand throttle to circulate.

Continued like this until coolant was steaming hot.

Revving the engine produced more bubbles, but doing so pushed coolant out, then the level dropped to below the filler neck, which introduced more air.

Put about 20 miles on it after this and the temp gauge still dropped a few times, suggesting I'm still low.

Coolant still isn't as clean as I would like, so I'll probably see more CLR (any threat to my new tstat?), but I'd really like to know how to do this right. Never needed one of those fancy funnels before, but never needed an OEM tstat or radiator cap before, either.

Cooling system health is damn important on these trucks. Especially for those of us in Phoenix. Appreciate the advice.

The altitude does not affect gearing. On NA cars the power loss is more pronounced as they have no means of cramming more oxygen in the mix. Based on previous posts he has larger tires and gearing matched to smaller tire. That being said he was running 4% loss in tq based on gearing. So now add a 58.6 HP loss in overall power at 10000ft of elevation and his truck feels like mule that is about to die. I know when people go to run Pikes peak they retune the cars / trucks at altitude to make them run the best they can.

the mathematical equation for power reduction due to elevation oxygen restriction is:
hp loss = (elevation x 0.03 x hp @ sea level )/1000

How does the altitude affect gearing?  I thought the ECU would compensate for altitude by riching or leaning the fuel mixture depending on high or low altitude?  I had only had issues when I had a carb at higher altitudes.  I went to altitude in my 95 SR and had no problems at all.

Yeah.. his work is top notch from what I see on the interwebz.. Since my truck is going to Ernest for regear / front locker, Mike's shop is 40 mins or so from there, figured I would have him help get the most power out of the truck.

AMM fab in AZ for a custom intake manifold

Whoa. Mine still in the business, then. That's good to hear. Your should ask him about ITBs while you're at it. Haha.
