why so against a standalone? there's a few plug and play options(well the power FC is close to plug n play anyways).

Megasquirt is pretty affordable, and Aaron has a good write up on it.

ECU flash tunes on an FC would be nice. That would probably be ridiculously complicated..Then again, if Rtek utilized a daughterboard for those features, who's to say it couldn't be adaptable to an older ECU. HW and SW limits obviously would be a hurdle.

that is exactly what the JDM chipped ECU's and the Rtek are, its a stock ECU with an added board so it can run a flashable chip. its the Rtek software that is the hold up.

if you find a Knighsports chipped ECU, you can send it to Knightsports with your mod list and some moneys, and they will flash it for your car.

Wait, so the RTEK 2.0 I have and do not want could be worth more than I thought it was? I even have the palm pilot all set up.

doubtful, this isn't the first computer ever built that will wind up in a museum, it's an archaic mod for an archaic ECU.

appreciation is in the eye of the beholder, and i haven't ever really appreciated the Rtek 2.x much because it was always a cheap and poor mod for people who couldn't spend a little more for a much better upgrade. i installed one into a customer's car and i kind of felt guilty for getting him to spend the money on it... even though it got some results, it was a slow and laborious process with mediocre returns.

it has its place for those who wanted a plug and play ECU, but there is now the megasquirt, adaptronic and there has almost always been the powerFC(S5 only).

To Greg's point, there is a niche application for RTek 1.x and 2.x in NASA time trials and road racing: "ECU reprogramming via reflashing or replacement/aftermarket ROM chips or simple ROM boards (OEM ECU housing and hardware must be used)" is a no-points modification. For SCCA road racing, although I used the RTek in the Improved Touring class (ITS), a stock ECU enclosure is not required: "The engine management computer may be altered or replaced," however "All air must also pass through the stock air metering device," which is ultimately a restriction to airflow and limits gains from a "higher-end" ECU such as a Haltech, as I've witnessed at the dyno.
