Default Is anyone rebuilding ECU? Or should I just get AEM.

So my ECU needs to be rebuilt. Any recommendations. Or would I be better off just buying an AEM because I don't have a boost controller and plan major upgrades anyhow....

I don't know what things cost these days like the AEM. but I have had my ECU rebuilt 4? years ago by

Rebuilt ECM & TCMs w/ 5 yr warranty - 800 241 6689

as well as my ECS controller last year.

Both continue to work, ECU rebuilds are $195, and you can optionally extend the warranty to 5 years which I did, for peace of mind, but I forget what that cost.

Chrome ECU seems popular and opens up options beyond factory or can be run as factory, but I think that's $1000??? but I am NOT an ECU expert, but did have a good experience with

The AEM Series 2 is a great choice if you plan on future upgrades.

Much depend on if you need to pass smog and if so where. Before my big build, I had a Jester Chromed ECU which made good power, had all the functionality to pass CA smog and had excellent technical support.

If you are planning a big power build (>500WHP on pump or >600WHP on E85), AEM V2 offers vastly superior functionality (at vastly higher prices) but will not pass a smog test.
