Bob_H Posted December 9, 2002 Share Posted December 9, 2002 They are a very new company in the US. look closely at the prices, and you might be much better off with the PRS-4 or PRS-8. About $400 and $900.. -Bob Quote Link to comment Share on other sites More sharing options...
z-ya Posted December 9, 2002 Share Posted December 9, 2002 Personally, anything that piggy backs onto a stock ECU, and costs $800 is a waste. Spend the extra $500 or so (or less) and get a complete, self contained programmable ECU to control the fuel and ignition. That way you can ditch the AFM, and a lot of other old wiring,and start fresh. Retaining the old stock ECU, and splicing this piggy back computer to is, cannot be good for reliability.

Bob_H Posted December 9, 2002 Share Posted December 9, 2002 Pete, The figures I quoted were for full stand alone EMS, not piggyback. I do agree with your sentiments though. Piggyback is kinda like a band-aid. If you don't need much accomplished, they are a great cheap way to get it done. But with what a full EMS offers, esp. for the price Perfect Power has for their race systems,(the PRS is their name for their stand alone systems), is hard to beat. -Bob Quote Link to comment Share on other sites More sharing options...
