Just reading thru some of the files.. Not that i can make head nor tail of them ..
But am i correct in thinking that our engine in standard form is good for 9000rpm ?
Or at least to raise 500-1000rpm higher than the current limit..
I see a few references to 9000rpm rev limit..
Obviously other parameters would need modifying as well .. BUT !!
Great work there.
I'd be interested to see the data .
Is it just me or is the zip file corrupted?? Can you please reattach it?
Cheers

In fact, I still think some of the map address are incorrect. But, the fuel and ignition map, should be fine.Originally Posted by WODJNO
Also, the stock rpm limit is at 7296, even with it, I am still happy with it, as I have seen some other VR4 members dyno graph from different forums, it seems that after 6500rpm both torque and HP curves go down, so, even I shift at 7000rpm, I am still ok on it.
Just tried the zip file, and it is fine, just simply unzip it as usual.Originally Posted by orionn2o

if i pm you, could you mail it to me please?
sure, no problemOriginally Posted by orionn2o
What we need to do is to pool our knowledge of the the ECUs and get a definitive list of what ecu's can be remapped/flashed and which cant and what cars or what years had which ecu.
I have no idea how to help, but am more than willing to take my dash apart to get any numbers off my ECU. Maybe if we set up a mini database of the ecu details against our car details that would be a start. Not sure if that is of any help though.

Hey guys,
Small world, the BarryC who started the thread on geekmapped is talking about MY VR4, that is where he got the def file in the first place.
BarryC the GENIUS responsible for all this, anybody wishing to contact or thank him can do so via The Irish Mitsubishi Owners Club. In the section for CW Performance.
Correct me if i'm wrong.

yeah I know..Originally Posted by dublee
Already sussed that 1 out
oh..the def file for VR4 was firstly seen in ClubVR4 in early Jan already....Originally Posted by dublee
Anyway, let's work together, and dig out more maps ^_^

So is this better than using a piggyback? I thought the ECUs were only good for a limited number of flashes then they have burnt out and cannot be reflashed...
My ECU is MD340289 from a Sept 1996 car and it's an A/T box. I have the E-Manage blue but a combination of ECU modification and piggyback data I think may be useful.

VR-4 #2 : Wallie, Finesse Green, 96 Legnum Type-S, Erebuni CF bonnet, Profec E-01 & EMB, TRE fuel pump, RPW Downpipes, De-Cat, Fujitsubo Super Legalis R, LC-1, NGK Iridium Plugs, SARD Radiator, Greddy Hard Rad Pipe, ATF Cooler, FMIC, Forge Recirc BOV, KAD 6 Pot 330x28 Brakes, HEL Braided Lines, 17"X8.0 Rota Torques with Wintrac Xtremes, Fully Synth Oils, Ultimate 102RON Fuel, Stainless Sills - Sold after 4 great years
All flash devices have a finite number of erase-write cycles - the worry is that the manufacturer may have gone with something really poorly spec'd so your limited with how many times this can be done. I've tried to find teh data sheet for the ECU processor but it doesn't appear to exist in web-land so who knows how many reflashes it will give.Originally Posted by Beastlee
BTW: well done to those who've managed this - I'm really excited at what this may mean
Flashes are typically in the hundreds...if not the thousands. Never seen less than that.
My understanding is that we've been able to reduce the RPM and boost limits with a MUT tool for some time......but it would dissapear with an ECU reset. Correct me if this is wrong? Whilst this isn't a full flash (obviously) the only info we had (until I saw the geekmapped thread) is that KC had changed these parameters. Changing a couple of addresses in memory (a contiguous address space) and then uploading it again isn't neccesarily a flash if you're writing into volatile memory. Hence my doubts. You reset the volatile memory, you lose the change (as per the MUT tool) so I wasn't sure if the same address the MUT used was being writted. As it appears a whole map has been written and tested, I am williing to accept that a full reflash has taken place.Originally Posted by scientist
If the parameters in the factory ECU are sufficiently well understood, it is MUCH better than a piggyback: you're not just changing the basic fuel & ignition maps, but can also alter cold start, barometric compensation, target AFRs, boost control, knock compensation targets / correction map, aircon compensation, fan compensation, probably fan temperature, rev limiter, MAF scale, fuel cut, and as the code is better understood complete software replacements are possible, offering just about anything: ALG, switchable maps, external device triggering, CEL reconfiguration, and loads more.
Not looked at this yet as it doesn't apply to my ECU, but I am guessing we're only looking at fuel and ignition definitions at the moment?
