http://www.megasquirt.info/ Man, if i had another bike i'd seriously consider getting one of these things & tryin to whack it into the GPX

Are you electronically minded?

I dunno how much of tweaking you have to do with this thing, but based on personal experience with the Motorola 68HCxx family microcontrollers/processors, the troubleshooting bit can be a real nitemare.

A mate set one of these up on his brothers car. Seemed to work ok.

He plans on using the MS2 for his 351 XB Coupe.

Seems pretty cool. If i hadn't already farked about to get mine to work i'd be tempted to give it a run.

I had problems with all microcontrollers/processors electronics. Thats why i gave electronics the flick and went to electrical.

you a sparky too mrmina?

for those interested in the megasquirt, check out this:

http://www.microsquirt.com/

its a bike specific version, should be out pretty soon

have a look here... http://www.msefi.com/forums/viewtopic.php?t=6627

specs on basically all EFI bike throttle body/injector setups... and if you look on ebay and search for "ITB" or "individual throttle bodies" you will see zillions of them usually selling for US$100-150 ... which is great value considering that includes injectors, throttles, fuel rail, regulator...

the software can build a base map for you if you give it the basic specs of your engine, and if you can tune carbs then you wont have toooo much trouble tuning by the seat of your pants, but it will need an hour or two on the dyno to get it A1..

i was tempted to go with a fuel-only setup on my 9R (keeps it simple not having to setup spark aswell, and the stock setup works fine) .... but ive spent enough on a bike that should probably be a stat write off as it is

I wouldn't mind betting that since these things are designed for a car they will only have a 5x5 load map (5 different throttle openings, 5 different rpm points). Works fine in a car where big mappings changes make little difference (due to initeria etc). On a bike little changes make a huge difference.

Power Commanders (from memory, had the tuning program on here somewhere, cant find it now) have a massive load matrix. RPM from 0 to 20k odd in 500 increments and about 10 different throttle opening points. It gives a lot of increments for small throttle openings, something like 1%, 2%, 5% and 10%, really important for normal riding conditions.

from the initial page, it seems it has a 8x8 matrix

yeah, its better to actually look than to guesstimate

the base model has 8x8, the megasquirt2 (and microsquirt) has 12x12.
