Dustin's Ke70 4Age 20V

If you have standard cams you will see low down torque increases if you use it.

I might even have an old solenoid here that I removed working, if so you can have it cheap, and if I can find the wiring connector you can have that too, so all you would need is 2 wires to connect and you can use it.  Where you would integrate it, you would retard the timing 1 degree and add 5 percent more fuel, and then tune back from there.  When you use cam advance you generally need less timing and more fuel.

I don't know why they removed it if everything was stock, I would need to re-wire it to the ecu as it's got a microtech lt10s

Microtech is unfortunately the worst possible choice for a 20v 4age, they never run especially well.  It may well have just not had enough outputs to control vvt, or no way to map its on and off rpm.  Also I think they come up a bit short on transient enrichment, and on a car with itbs where response is key, its the equivalent of fitting FCR carbs and then removing the accelerator pump, if you cant transient enrich.

Bugger iam prob best to refit the vvt and get a standard ecu. I do have an old power fc for a 16V but don't think that will work on a 20V

[LittleRedSpirit]

Standard ecu requires the distributor to work, and that requires cutting of the firewall, rendering the car unregisterable with firewall modifications.

Best to use an aftermarket ecu, if you can find an adaptronic e420c or e420d I can give you a map to use.  Check the microtech software and find the limits first, if you can just hook up vvt and its running ok, why change?  Hows it feel when you smash the throttle for the first second or so?

i had a video of it running like shit but its on my old phone that's broken. down low it sometimes backfires and carry's on, after about 4000rpm its fine anything before that is horrid.

That does sound like a VVT problem..  Even worse, when everyone has had a play with everything, you never know where to start!

if you still have that vvt solenoid ill buy it, i just moved into the new place so i can start working on my car for the first time in over a year.
