On pages #2 & #3, obviously the small numbers represent the pin number on the current harness you are dealing with.
Please take note of the notes I wrote for pin 44 on the stock ECU diagram.

 

On page #2, with the EVO ECU diagram, the bold numbers are FROM the stock harness pin #.
On page #3, with the 3g ECU diagram, the bold numbers are TO the EVO ECU pin #.

Just trying to make it as clear as possible to save people the $300+ it costs to get boomslang to make one.

I don't like the jpg images because you can see the should-be invisible lines that you get in excel for the cells...

 

great write up!

 

saved and ready for when I go turbo thanks for doing all the work cloud:yesway:

 

No problem, I don't know what I would do without this place. Everyone here contributes - I usually just organize it all haha

ps - thanks for the e.rep!

 

It's things like this that make Club3g a great place. Awesome work Cloud!

 

You sure made it a walk in the park for the 4 banger guys.

 

Does anyone happen to know the part number for the plastic connectors (both male/female for the ECU)? I wish they made ECU harness extenders (male and female ends) for AT RS/GS 3gs. I have one for my EVO8 ECU but that doesn't do me any good (Except the connectors on the ECU side) haha.

 

check boomslang.us i think they can provide the connectors you need. they can build harnesses so im guessing they can sell just the connectors.

 

The plan was to buy a female connector for the 3g and male ends for both 3g and EVO so I could make my own outside of the car... but they cost about as much as buying the pre-made custom harnesses!

I'm just going to hack my EVO ECU connectors and 3g stock harness... It finally goes in Saturday.

 

nice bro! any questions post it up,i will be glad to help out since im running the duals ecu's already

 

How did your car run with the stock EVO maps? I can't read my ECU at all so I don't know where to begin. I just need it to be drivable so that I can datalog/tune it

 

what size injectors you using??

you have to change the maf scaling,injector,latency and so on...i can send you my rom if you want,im using 450's blue top,it can help you out with a good start

 

I'm using blue tops too.

Your ROM would be a start... cloudinc00@bellsouth.net

I've already edited an EVO ROM to get rid of things like immobilizer and codes, etc. So combined with your map, I could save myself a lot of time and a huge headache

 

finally! A ROM with someone using the blue tops!

 

w00t, hopefully Saturday it goes in

 

Who tuned this ROM? Is everything the same as a stock evo except the injector scaling?

 

i tuned it myself....noting is the same as the evo,all the maf settings ect are from the stock 3g,the fuel and timing maps i redid it myself,(they were stock evo),im running meth on my setup,maybe the timing is alittle to high for your setup,every car react different, just start easy on it and redo the maps litle by little,have fun tuning!!! lol

 

fuel and timing I might have to adjust because I'm running an EVO set-up basically (besides timing/head)... EVO fuel rail, EVO FPR, and EVO fuel pump... This should get me to the dyno unless my datalogging says its close enough to where it should be and I can tune it myself...

 

im pretty sure your car is goin to be driVable with the rom,eVen to giVe it some boost!!! :ndance:

 

How badly is your timing advanced? Because I have a 272 camshaft and it may benifit from the advance haha. I'm trying to find my laptop to take it outside to the car but I think I left it somewhere (friend's house, dorm, etc)
