| Re: Fuel Regulator Question
Hi Ian
Glad to hear you managed to get your leak problem rectified. I have had some limited experience with ECU chips when I had my Nissan 300zx done years ago. I had a Uni-Chip installed and it did take a considerable amount of time setting up correctly on a rolling road. If you don't get any joy sorting your ECU out it may be worth contacting some of the TVR specialists like ACT performance of TVR Power. I know some of them deal with ECU mapping for Rover V8 engined Chimeras, Griffs etc. May be able to help you or advise on the best way forward. If you find that you need a new ECU also try Bellhill Garage who I bought my engine from. They break TVR's for spares and I am sure they would have various ECU's for sale.
When I bought my 4.5 Chimera engine from them I did have all the ECU, Injection set up and wiring. I was debating the pro's and cons of Injection versus a carb set up. In the end I went for a Weber 500 from RPI Engineering. If you speak to Chris there he would be able to advise and anwer any questions you may have. The kit I bought came with everything you need to change over from your existing set up. I had it all installed within a couple of hours and it started first turn of the key.
If you are going to go this route make sure you get an inch thick thermal gasket. This will save you from having boiling fuel in the carb as I did!. You will find there is two inlet manifolds to chose from. The JWR offenhauser manifold (that is lower in height) or an Edelbrock performance manifold. The Edelbrock is supposed to give slightly increased performance but RPI said they have never noticed any difference. I went for the JWR as height space is a bit resticted in the back of our cars!
During a moment of half witted incompetance I also managed to fit the carb the round way round (a common mistake according to RPI). The engine still ran but for anyone who is going to fit one the Edelbrock sticker on the carb should face the distributor. I really should read instruction more carefully!!. If I can be of any help Ian please let me know.
Regards
Simon
BTW. The pictures show my carb the wrong way round!!!!I kept them to remind myself that i'm not so perfect! |
