Flashing ECM wit different vin

[Ironworker85]

Hey guys I’ve done quite a bit of research on this and there is a lot of different directions people go. I have a 1998 international 3800 with a DT466e set at 190 hp which is a ST my buddy had a 2002 international with a DT466e come in his shop the other day set set at 230hp if I was to flash my 190 ecm to that vin of that 230 it should give me a extra 40 hp and keep me in the safe zone with out changing hpop? I know there’s a lot of knowledge on here jus trying to find out if that would work the way I think it would thanks guys in advance for any help

Sounds like a complicated solution to a simple problem - just reflash your ECM to the 230 HP setting.

[Ironworker85]

Reflash with the vin from the 230 truck your sayin?

[Brad_SwiftFur]

No. You do not need (nor want) to alter the VIN in your ECM. IH programmed in the various HP ratings so that a simple reprogram would use the already-present fuel curves. Flashing the data from the 230 HP rig into yours will simply duplicate the fuel curve settings already in it, and likely change a bunch of settings you do *NOT* want or need changed, possibly generating errors and/or check engine lights.

I read about guys getting the ST 466 up to 220-230 with out any other upgrades wat other options if any do I hav to get that up from 190 hp?

[cadillackid]

There are a couple options. With the god mode service maxx you can change the EFRC and HP on a 190 up to the codes for the standard torque 230. Standard servicemaxx won’t do it .
If the shop has a subscription to NavKal they may be able to reflash yours to that vin however that one is touchy with an ECM which already has a vin. I was only able to do it by using god mode to blank the vin which prompted navkal to ask for it. I think dealer level can.

I have no idea what type of shop and what software / subscriptions these guys have ..

[Ironworker85]

I have a friend who is a mechanic at a international dealer local so I’m trying to figure out a way to get my ecm turned up from 190 so would that make sense to blank it and reflash to the 230 hp truck?

[cadillackid]

If he is at a dealer of think he could just change the EFRC and HP rating, or open a ticket with navistar to do so then sync the ECM to NavKal which will download the new EFRC and rating to your existing ECM

When I looked into it I called the dealership they said I would hav to change turbo and injectors jus to go up a few hp

[Ironworker85]

That is wat got me thinkin to jus flash it to a different vin with same motor jus 230 hp

That's nonsense, they are just trying to sell you a ton of money in parts/work. Now if you were trying to go from 190 to 350, then sure, that's a big jump and more powerful hardware will be needed. But the 190 and 230 HP variants use (mostly) the same parts.

[Ironworker85]

Yea they don’t want to do anything for free that’s for shur. Does anybody know someone or somewhere I can send the ECM to get turned up.

[cadillackid]

I can do it if you are near columbus ohio.. I have the "god-mode" servicemaxx

[cadillackid]

brad is right.. the hardware on the 190 standard torue and the 230 stabdard torque are the same.. its when you go to the high torque variants thaty the turbo, injectors, pistons are different on the 466E

[Ironworker85]

I live where pa ny and no come together it would be a hike but I’m shur would be worth it. Do you need it in the vehicle or can u do it on the bench

[cadillackid]

I dotn have a bench harness set up that doesnt throw a zillion codes.. ive only ever done them in the vehicles or sent people the program if they have the nexiq or clone device

[Ironworker85]

I hear ya can u feel a good jump in power from 190-230 I’m shur it has to be noticeable

[RolesvilleMarina]

I took a 1999 ECM and swapped it with a 2002 ECM

I had no idea if I would see sparks or not

buses didn't seem to notice

I guess it all depends on if other parameters are the same?
In my case the HP was the same on both

for what it is worth, nothing exploded

[Ironworker85]

Well that’s good to know this is harder then I thought it was guna be to get and power out of this 466.
