can ms3 manage a 2zz-ge engine?

Barton · Post by **Barton** » Mon Aug 05, 2013 3:50 pm

Hello to everyone, have someone tested a ms3 in a celica 2001 gts?? can the ms3 manage a 2zz-ge with all the oem triggers and the vvt system (this is where I'm more worried).

Thanks

Googled the 2zz, and it seems to have VVTi on the intake cam only.

MS3x systems has the ability to control 1x vvti solenoid in the current firmware, so unless the trigger-system itself is very odd you can be confident it will work.

This one is believed to have a similar crank and cam pattern to the 2JZ, but we need someone to try it out and confirm this.

The triggers are the problem, I started up a K24a2 with jame's help, but I'm not been able to test the vvt system, but they trigger decoder was already in the firmware, but I do not see anything about the 2zzge.

I found this picture:

and a forum: http://adaptronic.com.au/forum/index.ph ... 265.0;wap2

it seems to be 36-2 crank trigger and 4-1 cam trigger, there is a thread in ms3 development about this.

Ok Matt, I'll make some logs to confirm the triggers, but after that you think is possible the management of this engine?, I ask that because someone ask me wich EMS can manage 2zzge engine?, I believe the MS can do it but before I tell the car's owner that, I have to know if I have your support to complete this task.

After that I believe others with that engine would like to acquire MS.

thanks

I found this picture:

Perhaps just shop off two of the rotors, and leave one for ms to sync.
Then you could use the regular trigger setup

I think that would create a problem with the vvt, because it needs that arrangement to sync the camshafts, but I do this as a job and the car's owner wouldn't like to chop the that trigger.

It seems like, at most, the code would need some minor tweaking to make the 2JZ VVTi code run in 4 cylinder mode.

Ok Matt you are saying that I can tell the car's owner that the MS has the complete support for that engine?

Not yet. It is likely to take a minor firmware tweak because it has not yet been tested on one of these. But it is almost certain that it will not take a very big tweak.

I can help if you need, I do not know if you have an engine to test that new code.

Mostly, we'd need someone to hook up an engine and make a composite log, then try test code to be sure it gets the spark at the right time.

Ok Matt i'll explain this to the car's owner I do not think there will be a problem. I'll write back when I got everything

Hello, here are the logs from the 2zzge engine (from a Toyota Celisa GTS), it has 3 teeth at the intake camshaft plus the normal 36-2 at the crank, there is not a vvt reference sensor like the honda K series at the exhaust cam, but I do not know is already exist a decoder in the ms firmware, I need help here.

besides that, I need some explanation how this system works, because I understand How the K series uses the reference sensor to compare the angles between the two camshaft, but with this engine how it works?

thanks

That pattern looks easy enough to understand. However, there isn't a generic way to handle that at present, so a new decoder would need creating. I'll have a look.

Ok james, notify me if I can help you with anything

Do you have any settings for this engine? i.e. do you have it running with "Toothed Wheel" ? I'd need that to build-in the trigger teeth into the custom decoder.

I'm looking to follow Matt's idea of adapting the 2JZ VVTi decoder. Currently that supports 6cyl, has untested numbers for 1UZ 8cyl and can be made to support this 2zz-ge 4cyl with 4-1 cam.

Yes, but I'm using the 1.2.3 code if you need a log using the pre 1.4 just tell me

Test code sent by email.

Any feedback?
This is the same engine as : http://www.msextra.com/forums/viewtopic ... 25&t=57009 I think?
