2000 Toyota Hiace (originally 2L diesel)
Engine 4,0 V8 1uz-fe with a Holset HX35 turbocharger
This is the "early" 1uz with 10:1 comp and the stronger rods.
Used all original sensors
For the trigger I used original 12T crank wheel, grinded away one tooth. (12-1)
Replaced injectors with 440cc 7m-gte supra injectors.
MS1 with extra code controlling both fuel and ignition. I used original toyota coil drivers.
I'm into the coarse mapping phase now, but everything seems to work fine
I will attach my last "temporary" msq file please note that the ignition adv. table is only used for coarse mapping purposes and NO high RPM, Load/ boost.
-EDIT- deleted old msq...
Cant wait to get to the dyno...

I connected the IGT signal cables to spark output A and Spark output B Then I left the IGF and Tach pins unused, and connected them to a switched 12V through a relay.
Then used the coil output as the negative coil wire.
PS. it's important to ground the ignition module housings...
Thanks, the same to you! there's really hard to find others running uz and ms.. What car do you run your 1UZ in? I did not have any issues with the sensors. Did only use 3 wires of the TPS and one coolant sensor. But I do have some issues with negative spikes on the tps signal and positive spikes on the colant and mat sensors. I used a 3sgte MAT sensor btw.. I'm into the troubleshooting for that, Will try to see if the alternator has something to do with it.podge wrote:thank god for that, someone else with a turbo 1uzfe running megasquirt . my setup is basicaly the same as yours, but my ms will be driving ford coils direct and im using a 36-1 crank trigger wheel and two ct26a turbos. did you have any issues with the lexus sensors or did they run fine straight away all the best with this podge
Do you Have a tuned ignition map for your engine? I cant find one anyplace... I'm looking for something to start with when I'm going to the dyno.. needs to get the fuel economy better..
Here's my latest msq file. Seems for me like the ignition is way to retarded but the A/F is starting to get better.

BTW folks, this car is running really strong already at 0.5bar boost now
I'm up running on 0,5 bar and it's running really smooth. I will go to a dynapack with it next week, to gain some Nm at cruising.. I''m using this car as my daily driver so I want it to be fuel efficient. I'f everything works out well, I might be tuning it for more max HP as well.
here's the latest msq as well.
I sorted out some signal problems by adding bigger ground wires. elswhere it's just running smooth now.. cruising around with 395hp and 610nm at 0.5bar. i'm into testing my 044 bosch pump to see that it's not worn and one day I vill boost more and gain some more hp.. and alot more nm.. hehe how's your mr2 1UZ project going?
glad to hear your project is running well. they are impresive figures. havnt had time to finish my project as yet but hope to do so this year. arnie`s car is going realy well i think how small a world is it will post up when mine is completed all the best podge
