There are several people running megasquirt with 1uz. Most are using ms3x but it can be run using ms2 with or without additional ignition drivers. I have ms2 wired to the factory ignition pickups and batch firing the injectors, its kind of inefficient but works. It would be nice to run edis...

Have you ever wired in a separate tcm from a different vehicle?, jeep for instance.. that runs an a340

i dont have a scan tool, scope, or a dyno. i did try this: http://primavistalab.com/myengine/ but cant get it to connect to the diagnostic port

thank you, have you had any experience with a diy controller not including the suprastick?

i am building a manual shifter for my 341 and was wondering will it harm anything to activate the lock up manually by supplying full 12v/ground to the solenoid instead of the pwm it would normally receive? i know all the solenoids share the same coil resistance this leads me to believe they...

is there anyway to monitor ignition advance with the stock 1uzfe computer? i have seen someone use a camera, timing light and a zip ties but i was hoping for a little less crude approach

I told ya I frequent the same establishments.. I did have a fuel leak around the tank gasket but its been fixed for a few tanks. I'm thinking I may have plug leads or cap/rotor problems. It is rock solid idling though. I am going to try and do compression test over the weekend and see if that...

I have the same setup and am only seeing 12.2 MPG to your 16.7 How did you run your exhaust and intake?

as far as soldering the caps it was easy (for me) 15 minutes from the time it was opened up till i put the screws back in (9 in total) i used a ground strap to alleviate static damage and didnt get up till it was done.. didnt make much difference as far as the engine control stability. also it...

i definitely have something going on. i found last night that i have no power to my hi beams after the swap. just to be sure 12v to nsw is the same with vehicles running the a341e (now f)? from what i read through that thread that all people experienced positive results for a variety of...

thats what i am thinking. i ordered capacitors to replace the existing ones in the ecu even though they look fine. i have read on more than one occasion that they can be bad with no visible signs of failure.. a good write up over at club lexus...

before i swapped this in the trans shifted fine despite a no.1 speed sensor error.. now even having that fixed it refuses to shift. i am not seeing any power wires i have not hooked up were would it get the 12v from?

ok i understand that now why is the ecu not pulling it up to 12 volts? also o/d off light is on always except when checking codes than it blinks appropriately for said codes when i remove a component to cause one otherwise no codes

ok so there wasn't 12v at nsw so i helped it to see 12v and no difference in the diagram it shows nsw should only see 12v at cranking why should there be voltage during on/running state?

i do not have 12 volts at this pin at this pin. there is .6 volts at all times key on i am attempting to use the drive shaft flange bolt heads for a 4 tooth rotor. i get an a/c voltage doing this so i believe it is working. i am not throwing codes but i have not had it on the road yet...

I guess I was going for a dual install. didnt want to trim the crank wheel 12 -1 I am going to attempt to keep the stock setup and experiment with the ms so it wouldnt be completely down. I might be keeping the factory auto using the inchworm adapter so keeping the computer happy was part...

anything new Im about to swap in the 1UZ in my 4runner. As I am already running MS2 with my 22r TBI.. it seems like a no brainer to keep it for the 1UZ. do you guys have a good base tune? what did you do with the IAC? and why not wasted spark, EDIS is easy and plentiful.
