tvr ecu

hey anyone out there ever tried an ecu out of a tvr 4.6 or 5.0? i just bought one off of ebay uk without asking first. Guess I'll find out. I run a 4.6 with just about all the goodies and thought this would be the last choice before carbeuration.
thanks

You could always go with an aftermarket ECU and dial-in the performance yourself. Megasquirt would, I believe, use your existing EFI components and allow you to customize the air/fuel maps...

Brian,

Very interested in what you experience with the tvr ecu. I'v been running a 95 Disco ecu with an RPI chip for the last two years, and seem to be doing okay except for an 1100 rpm idle and having to retard timing to about 2 degrees to suppress pinging.... ;P

Well i put the tvr ecu from a 5 litre tvr chimara in my 95 defender with 4.6 -hot cam- done up heads- free flowing exhaust blah blah blah. It runs like a champ. the ecu is a 14cux with reworked fuel mapping for a larger motor- like the 4.6. The best part about it is it only cost $150. on ebay uk. Smoother idle no bogging no issues. A noticible difference pushing 5th gear on the highway- blowing by everyone at full speed. nice purchase if you have a 14cux ecu already.

No pinging above 3500 rpm? Do all the aux items like air conditioning work as usual wiht the Chimera ecu in place? Timing standard at 5 degrees?
