schaafman Posted May 25, 2010 Share Posted May 25, 2010 Dear All, I recently bought a fairly low mileage 3.9 EFi engine, gearbox and ECU. Upon opening-up the ECU i saw that the traditional Lucas chip housing had been removed and a rather alien chip had replaced it. Can anyone identify this for me? Please see attached file. Kindest Regards James Quote Link to comment Share on other sites More sharing options...
ChrisM_110 Posted May 26, 2010 Share Posted May 26, 2010 That's an Evo Star*Chip from BBRGTi. Quote Link to comment Share on other sites More sharing options...
schaafman Posted May 26, 2010 Author Share Posted May 26, 2010 Evo Star-chip eh? just googles them and found their product list, these cost £599?! i bought the engine, box and electrics for only £100! good buy I say! What sort of BHP increase are they expected to do? also does anyone have any other knowledge/comments on these chips? James Quote Link to comment Share on other sites More sharing options...
SteveRK Posted May 27, 2010 Share Posted May 27, 2010 If your engine has catalysts & Lambdas then there will be no difference up to 3/4 throttle as the feedback loop to the ECU will ensure only the optimum (pre-set fuel map) amount of fuel is fed through the engine. After 3/4 throttle I guess it might pump excessive amounts of fuel into the engine and result in a few extra BHP but without the usual engine performance tweaks (camshaft, porting etc.) on a std' engine at best i would guess 5HP?

Hybrid_From_Hell Posted May 27, 2010 Share Posted May 27, 2010 Has the tune resistor in the loom been changed ? Nige Quote Link to comment Share on other sites More sharing options...
schaafman Posted May 27, 2010 Author Share Posted May 27, 2010 My current engine and my new(er) one both a pre-cat and so don't have Lambda's or a tune resistor. RPi will be refurbishing the engine next week, high lift cam, vernier pulley, stage 2 heads. James Has the tune resistor in the loom been changed ?

James never mind ensure they give you a good warranty print out because you will need it! you have to have a tune resister so the ecu knows to look to see if lambdas are fitted or not also the world market fuel spec too Quote Link to comment Share on other sites More sharing options...
