Evoscan tuning/reflashing

Problem you are going to find with tuners is that unless it has a V8 or turbo then alot don't want to know about it because it's outside their comfort zone. There was someone tuning the NA CJ Lancers down in Vic I think at one point, might be worth seeing who is doing that and maybe they would be interested.

For dyno tuning though expect $700+.....
 
There's a 69 head on eBay atm, you should buy it and hot it up with a cam, porting etc etc. So you have less down time

I've heard mixed stuff about RPW so who knows, at least it's not like LLT where you mostly hear crap and rarely a good news story! Yet people still seem to deal with him...

Irving (ofey) has the cable to read and flash a ROM but you would need to have the definition file for your ECU if you want to start editing parameters in the ROM. You'll also need to find a tuner if you want to start playing with the AFRs....

Liam posted an URL to EvoScan website earlier which has 4G69 def file on it..

Liam we should talk to Irving from club CJ maybe he can help us, he has all the gear

tempting, but as Ryan said, messing with air fuel ratio's could be rough without a pro to help

If you have your own wideband lambda you can do your own fuel maps easily. The problem is the ignition maps. You can't see gains on the street (well, you can do SOME adjustements based on GPS testing). But for the engine, the most important thing is to have the right AFR's and have the ability to datalog that everything is in order and there is little to not at all knock (pro's say that Mitsu ECU's knock readings up to 7 show only a bit bad burning on the combustion chamber. Knock sensor does see also abnormal pressure wave's, that's why.)

For example the EvoScan is native compatible with Innovate Wideband lambda. So then you can datalog current AFR through lambda -> current map value in use -> all other information needed for tuning like RPM, TPS and so. Then you can open the datalog XML and search for "unwanted AFR" -> see on what part of the map it comes from -> make few adjustements and run again.. again and again 'till they're okay :) And to be honest, if you are changing cams you should already be VERY familiar with this. Damage to engine without fast changes made to fuel maps are more than just possible.

We made low RPM ignition map changes to my CS also with Nokia cellphone and RaceChrono. 80-120km/h run with 4th gear and flat out before 80 and over 120 on the same part of road. With changes we got off 1.5 second of the first run's time. But on dyno, of course this could be done much easier (but much more expensive).

Also if you want to be sure, you can make your own knock headset from Peltors, some nylon pipe and a T-connector. It's much better than just trusting the OEM sensor.

Don't be so in-confident!
