Have you got the rom fella? could you post that up. I have a friend on Geekmapped who is very intrested in looking into this for you.
But he needs to change the XML so it reads right.

Ok, there's one problem. I suspect that rom id isn't in the same place as it has a rather strange id number....But here are the rom and the xml. Extensions changed! Based on vr4 xml so there's lots of faulty data, only rom id, fuel and ignition maps are certain.
Come over as a .wmv?
You cant post xml or rom files? You just have to change the extensions. The first one is .xml and the second one is .hex.
Cant seem to do anything with that most just pop them in a zip file.
Does this work for you then?
If they are designed only for 93-94 octane you might get some gains, commodores here run on 91 on their hi octane maps and you can get massive gains from ignition timing, different company, maybe a different philosophy but maybe worth a go....
so final verdict? can you do much with the n/a v6 engine? as i do think they are so under powerd & would be nice to see what can be done to improve
they are basically the same as an FTO, so air filter/exhausts will get you up to 5bhp. Remap or aftermarket ECU up to 10. Cams are probably your best bet. Or a DOHC setup from a VR4.

2.5ltr V6 Turbo FTO
Just a K&N filter in the standard Airbox seems to work very well in my case (see Sig) Would like to change the exhaust but I think the cost would outway the gain.
e5dcb: Have you had any progress with the v6 rom?
I have sent it to the guy who mapped my evo but nothing back yet ie if the maps good or could be adjusted abit.
Looks like some of the FTO's have the same 7202 chip, but I seem to be having problems pulling the rom off at the moment.
keep us posted guys! im very interested in the outcome
I don't think you need much else to tune N/A than fuel and ignition maps......and I have already found those....the location of rom id seems to be the issue now.
Just my 2 cents in re NA Mitsu donks.
I have (selling it) 3L Magna with CAI, K&N, Headers, XForce muffler and when tuned (Interceptor ECU) from Std map on dyno we gained some 15kW at wheels. Magna tune was obv for 91 oct gas but I'm using 98 now. This hopefully gives an idea what can be gained on that size NA engine.
On-road tuning after dyno using an AFR Gauge changed the low load and RPM figures a bit and I was surprised how lean I needed to tune it to gain best torque - 15,5 - 16. Not 14,7 like lot of ppl seem to think is the most desirable AFR. Depends on the engine!
~15.5 is known to be the best AFR for closed loop. 14.7 is for emissions / catalytic converter operation which is why manufacturers use that AFR. It isn't really anything to do with the engine as such (has to be 4 stroke petrol of course)
I re-connected the std ECU back once to read its AFRs and yes it was a bit like you say. Seemed more like solid 14,7 then richer at higher loads (TPS / BF opening) and RPM.
I used that 15,5-16 figure only on very low load and RPM - 1-7% TPS and 1000 - 2000 RPM ruffly. AFR then gets gradually richer "down" to 12s on high loads and RPM, in a linear fashion. Also, Dyno tune is generally done with WOT, starting from say 2000 RPM if practical. Good tuner will try to simulate on-road driving on the Dyno, but it's not easy there fore doesn't provide best results on that area. I have seen a "flashed" Magna AFR and it was almost solid 14,7 all over. Hmmmm..... You want it richer at high revs.
Some engines prefer richer mixture than others - I think older big donks. Can't swear on that cos haven't tuned any other than the Magna engine.
