Watch out guys... this is a long post! :p
xxb4xx is talking about reprogramming the stock ECU. Hondata have already figured out how to do that and it's how they reflash the stock ecu. Of course, you have to be willing to take the risk of your ECU getting fried in the process and (potentially) having to wait for a replacement. If there was a reliable way to tune the car using the stock ECU that'd be great. The latest honda ECU's have some pretty advanced features.
The only way you'll be able to completely tune the euro (which includes tuning the VTC, VTEC, RPM limit, fuel/ignition, the Drive by wire throttle etc.) Is to go for an aftermarket standalone ECU that can control drive by wire throttle and has enough auxillary outputs to send all the neccessary data back to the stock ECU to run the air-con and the dash. The Honda k-series ecu's send information (to the dash for example) via canbus so untill someone is able to decode the canbus 'language' that the honda ecu uses, you'll need to keep the stock ECU if you want your dash to work.Quote:

Personally I've gone for the Vi-Pec v88. Which is currently the only standalone ECU that can control Drive by wire throttle for under $3000.
I looked into Motec and the cost just isn't feasable to me...
M400 ECU (up to 4 cylinders sequentially) = ~$3100
Drive-by-wire option = ~$500
Variable valve timing = ~$700
Wiring loom = ~$1000
Cost to wire the ECU into the car = $1200
Tuning cost from scratch= ~$1000
Compare this to the Vi-Pec...
V88 ECU (controls up to 8 cylinders sequentially) = ~$2500
Drive-by-wire = included
Variable valve timing = included
Wiring loom = included
Cost to wire the ECU into the car = did it with an aeronautical engineer friend of mine (but had to buy a genuine hard copy of the honda accord euro workshop manual at a cost of $450, also bought some solder, heat shrink etc. and an extension harness from boomslang).
Cost for tuning from scratch= ~$600-800
The bottom line is - you won't get out of this cheaply... But the Vi-Pec v88 is the best option. You wouldn't have to buy a honda service manual either since I've already put together a wiring diagram to wire the V88 into the car and may even consider putting together some plug and play harnesses if other accord euro owners start to show interest.
