Will my ECU send out the right error codes?
I have a 7MGE ECU on a 7MGTE.....I know I know, I bought it that way....Yes I plan on changing it along with the wire harness....But for now I want to check for any problems I may have so if I were to check the error codes would it give me error codes for boost leak? Or running lean or rich??

I hope there's a good fuel controller in there... if not you may find yourself looking for a new engine sooner than you'd like.
No, for reasons beyond my comprehension the GE ECU has no functionality for diagnosing turbo related problems... There is a lean code but it simply indicates that the system is taking in way more air than it thinks it should according to the fuel maps... absolutely no good for any real diagnosis of air/fuel mixtures; What you'd need there is a wideband.

You might get all kinds of codes flashing. Does it even run good.

Yeah it run's drives really good but I don't drive because I'm afraid it's probably running really lean, so before summer brakes I plan on installing a GTE wire harness, ECU, maft pro, and wideband sensor then have it properly tuned and go from there.
Thanx for you help guy's, I was afraid that would be the case.

Get thine arse to a performance shop for a couple dyno runs. Do a slow one as well; This will give you a graph of your AFR (make sure their dyno printouts include that, it's uncommon but some shops don't unless you ask) at each RPM. It's only going to cover the higher loads but it'll let you know if there are any danger zones.

Now this has got my wheels turning as to why someone would do this....
The GE Ecu won't have a fuel cut correct? With this GE ecu wouldn't the BOV then be able to be vented to the atmosphere with out significant rich spot between shifts? Of course a fuel controller would be needed to stop detonation from even the stock boost. But if the other questions above are both correct then that could be an alternative to the Lexus Afm.... and save mad tuning for the bov venting normally required on the gte ecu? And this should able to be achieved with a simple piggyback system right? Oh and I bet if u open the glove box area you will see where the previous owner had the fuel controller hooked up!
