Just to confirm - Stock ECU works ok still without the AT connected? (650E)

[Spinnetti]

I know lots of folks have done manual conversions - What I'm not clear on is if the stock ECU has any issues with all the trans plugs disconnected? Looks like I have a line on getting a standalone TCU for the 650, but unclear if it will give me ECU issues without anything connected to the stock trans plugs... Thanks!

VVTI ecus will limit power and torque without a/t in place

Thanks George. So do I just need the TCU to provide particular signals back to the ECU or is there no practical way to run a aftermarket trans controller without also replacing the ECU? (anything plug and play to replace the ECU/TCU?) The trans logic works horribly in a race car. A bit at a loss on how to fix.

Remap stock ECM for M/T and run anything for transmission without sacrificing power and torque

Thanks - Who/Where can I get the stock ECM remapped for MT? Are there also performance remaps?

Depends on your location and yes we offer them too

Im in the USA. Do these motors do well with a retune? If so, have any numbers for it? I'd be interested in being able to run a standalone transmission controller, and also have improved engine tune. I have no cats, very open exhaust and intake, but otherwise basically stock motor and exhaust manifolds.

OEM 3UZ ECU TUNE/FLASH

Hi All, So I have been doing some research regarding the OEM lexus 3uz/1uz vvti ecus which are OBD2 compatible. Many claim that tuning the oem ecu via OBD2 is impossible(well all info online is dated pre-2010 anyway). There are actually multiple tuning interfaces that have cracked the...

So I have a 1uz vvt not a 3uz... So nobody is running manual successfully with 1uz vvt, or is it possible to tune the 1uz also? (98' GS400). Maybe I'm asking the wrong question - My real need is to improve the shift logic of the 650E attached to a 1UZ VVT. What's best way to get that done? Thanks...
