No Secondry Power - ZR-1 Net Registry Forums

Hi All
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 so I think everthing is OK.
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
