Secondary Power
Hi
I've fitted an LT5 to an Ultima GTR it uses a Porsche G50 gearbox. The cars running well but the second thottles are not coming in.
The engine is 1990 and uses a seperate ESC module for the Knock sensor.
The power key has been earthed out.
There is no speed sensor as I can not fit one to the Porsche box so I get the assosiated trouble code.
I sometimes get a cam sensor code.
I don't get any vacuum or second injector codes.
The engine pulls smoothly with no hesitation.
There are no indications of lean mixture.
The engine revs up to 7000rpm ok.
Can you help?
John
