Or can I use the ecu from my vq30 with a 3.5 swap on my 4th Gen. My timing jumped and bent the valves a little. As long as I'm putting a new engine in I'm thinking of doing another vq35 swap without megasquirt. I don't wanna have to swap all the nats crap with it. Thanks

 

Get a jy ecu

 

Where do I find that?

 

At a junkyard? jy ecu=junkyard ecu, just in case you did not know.

 

Are you a wizard?

 

Do some research on a full ECU swap. You may be getting in over your head.

 

Yes ive swapped a 3.5 in a 4th gen before but I used megasquirt as a standalone... Custome wiring harness and everything else. 5spd ecus are incredibly hard to find where I live. This is why I asked if I can use my current ecu with the 3.5 engine as a second question.

 

Search the classifieds the pop up all the time. But why go from megasquirt to a stock ECU?

 

Auto ecu can be used with nistune

 

It's all in the stickies man. Swap 3.0 sprockets and chains onto 3.5 and then run 3.0 ECU.

 

Yes, the 3.0 ECU can be used. Have a look in the All Motor forum in the stickies. Most 3.5 swaps around here are done using the 3.0 ECU.

Awesome. Thank you. This is what I wanted to know. And to answer a previous question... I want a stock ecu because I sold my max with a 3.5 swap and megasquirt. The 4th gen I have now is stock and the timing jumped and bent some valves. The car isn't running right anymore. So since I'm changing the engine I may as well swap it with something better.

 

I can't seem to find the all motor thread at the moment. If you know where I can read up on it could you please link me? Thanks

 

The 3.0 ecu has no control for the variable valve timing. It will not run a 3.5 in stock trim. You will need 3.0 timing components swapped on.
