2006 Infiniti g35 i swap the vq35hr to the de and i have a few issues, everything runs and drives fine but i have 4 engine codes p0078, p0084, p1084,p1078 which are the sensor that arnt there on this engine how do i repin the ecu to get rid of these engine codes?

 

How did you swap that without changing the harness and ECU in the first place? The vq35hr has 2 throttle bodies. I think those codes are for the exhaust cam timing sensors.

 

Sorry new to the tuner community i guess its not the hr i swap a high rev to a non high rev

 

Oh, so your 06 is a 6MT with a vq35de "revup" engine, and you swapped in a plain vq35de?

Take that engine back out, use the short block and transfer over the revup heads, oil pump, and timing stuff. Then reinstall.

Only way to get rid of those codes/lights is to install a revup engine, or find an 04 6MT ecu.

What was wrong with your old engine?

 

Yeah basically you used the wrong engine. The VQ35DE block came in multiple variants, the Altima/Maxima are not compatible donors, the G35 version came as the "rev-up" and non rev-up versions. The rev-up was used on 2005-2007 6MT equipped cars and had variable exhaust cam timing added. The short block is interchangeable but the compleete assembly is not, the rev-up had different heads, timing cover, oil pump.

Google the differences between them
