Problems with ecu

karlisn · 10-31-2014, 08:05 AM

Hello, I have a problem with my racing 350Z body (fiberglass body), but placed inside the Infiniti G37 engine vq37vhr, driving about 10 km / 6 miles lost power from 7600 rpm to 6000 rpm Engine errors that occur are minor. try to find the problem, or better to remove all the orginal wires and installed an adjustable sports management block? it is possible to install the adjustable ecu?

If you have mods, get the ecu tuned?

If you have any codes from the ecu / engine light on, then that is a different story. I do not understand what the fiberglass bodykit has to do with the ecu though

I'm guessing we are losing something in translation

Step one is always to scan for codes in the ecu. I wouldn't touch anything until that is done or you could create new problems in the process.

Looks like I'm not the only one here

Swapping anything from 350 to G37 engine would make me believe there are going to be issues.

I'm sorry about my english language.
My car has 350Z body, but inside is a Infiniti G37 engine, gearbox, original management and wires VQ37VHR , but some modules are removed excess which are completely useless. car like all VQ37VHR has direct injection system.
Removing all the orginal wires management are posible to instal sports management and wires?

What you want to do is reflash the factory ecu with Uprev, not replace it. But you need to find out what's wrong first.

I see what you did. You transplanted a VQ37VHR into your 350z. You are in uncharted territory. Scan for codes first. Correct those issues. You can try to tune the factory ECU with UpRev. If that doesn't work, a standalone engine management system will be you next step. Something like a VIPEC engine management system that can be custom tuned.
