My car has many blue blue wires, maybe transplant some blue wires from a vr4 into the rvr!

is this like the 21st century version of the yellow wire?
Stops fuel cut more or less?

from memory i thinkit has something to do with the line pressure in the auto

Found my password...Graig the blue wire you're talking about is the wire on the
pressure control solenoid...A 4.7 ohm resistor will reduce the 5v power going to
the A & B solenoids to 2.3v...This makes it a harder gear change at slow speed.
The TCU senses the tps position & engine revs & varies the voltage from 0 to 5v
to the A & B solenoids acordingly..WOT @ 6.5k gear change = 0v
Slower speed gear changes will be between the 0 & 5v < being the mildest change.
But I don't advise you to play with this with a stock box. Just explaining it to you.
Cheers !

Thanks Aldo!

Hah, I was only talking to VR401 on the phone the other day regarding this, we're in the process of trying to find a way to control the voltages to suit the drivers needs. It's one of the mods I will do.

He also has another mod you can do in the valve body housing to increase line pressure from 130-ish to 154 as the standard pressure..

I'm slowly learning more on how to do this stuff

Now that I know who you are Rockabilly, I'll stop talking hahaha.
