I looked at the manual.
It looks like a nice inexpensive piggyback extra injector controller but it does not intercept the OEM injector signal. It does drive injectors based on rpm and MAP but it has no injector input signal. Therefore, OBDII and the stock ECU will not like this unit.
Nice device but not exactly what we need.
One other nice thing in the future is the "self tune" capabilites of the Power Commanders. In motorcycle use, the dynojets can be programmed to accept the wideband O2 signals and the PC III inputs. This means that with several quick runs on the dyno with a selected a/f ratio, the PC III reprograms itself to give the fuel needed for the selected a/f ratio. No brainer tuning.

The Smart tuner intercepts signals going into the stock ECU.... this is standard fare for most piggyback systems. It still does not directly modify the injector signal outbound... so it still has the same issues as other piggybacks.
These guys build things cheap enough... why don't you see if they can build a outbound injector signal intercepting unit. With OBD II / III it maybe the only emissions legal / long term fuel trim avoidence way to go.

I have talked to Peter Ludwig - his dad is the designer.... used to work for NASA ... !
He is more into developing other systems that require no tuning.... I was blown away when he showed me a 5 and 7 wire O2 sensor which takes full control of an engine map and once the engine is given enough prime fuel, the engine will crank over and start... the O2 sensor takes over and tunes the engine according to your fuel ratio requirements... Mainly used in 2000HP and up top fuelers and dragsters in prototype stages I believe..... Imagine trying to hold that power on a dyno!

cheuk,... i have already emailed you regarding a similar topic,...
i am very interested in this, has the wiring diagram shown it to be friendly to our cars?
I understand i have to purchase the Suzuki GSXR1000 version
Any ideas where i can find a nice cheap retailer
???

Cheuk in Seoul:
It will drive high ohm injectors upto stock injector limits. The PC III can directly change injector pulse +/- 100% this should be able to make the adjustments.
Could this also be used with low ohm injectors??? i have the darn venom kit in there that also works through injector pulses,... im not sure if messing with the ohms will screw around with it

I'm not sure if it will work with low ohm injectors... the PC III for the Suzuki was designed to run high ohm injectors... there MIGHT be others that can run low ohm injectors.
We are still waiting for the wiring diagram.. they are being a little tight fisted about this. Anyways we already have it for the fuel portion.
You should be fine for using high ohm injectors... since high ohm injectors are available upto 550 cc.
