I'm looking for one of these, and would be interested in this one but you know these are only £345 brand new?
GREDDY E-MANAGE ULTIMATE PIGGYBACK ECU FUEL CONTROLLER 15500501 | eBay granted, that's without the harness etc, FWIW I sold one 3 or 4 years ago when I broke an MX5 turbo "project" with a map sensor, software and a plug and play boomslang harness (which are $299) for £250
As you said that does not come with the map sensor or harness. This unit is in excellent condition boxed etc as new, I'm willing to consider an offer but in no rush to sell as I paid much more than £250 for this!
FFS, It's £270 plus international shipping, plus fees, plus VAT and duty, and thats just for the ECU. Expect to pay a little over £400 without dodging the tax man and wait 2-3 weeks for it to arrive. The harness and sensors cost a fair bit too.
haven't had those issues with nengun in the past but no worries im sure you could get caught out. anyways no problem, good luck with sale. Phil
