Megasquirt MS3

My car is quite well tuned with MS1 but looking at MS3 it may be worth upgrading.
Onboard logging, larger tables, better resolution, possibility of sequential injection, additional channels

Has anybody upgraded from MS1?
Have you found it worthwhile?.

Depends on your engine!

Hello,

Unless you are going to make use of the sequential injection (by fitting a cam sensor as well as the crank sensor) you don't need MS3. MS2 is a cheaper upgrade and also uses the larger tables and finer fuel control. The MS2 chip is about £80, fitting £20 (or you could do it yourself)

Let me know if you need any help.

Cheers Dale.

Upgraded to Omex 600 here.. what a relavation..

Sorry to hijack thread but what throttle bodies are you guys using I have a 600 omex to go onto a Zetec, can't decide what to go for jenveys and the like or motorbike!!

Changing from Megasquirt 1 to OMEX 600 would be an upgrade (just), but changing from MS2/3 to OMEX 600 would be a DOWNGRADE.

So, if you have an MS1 then a upgrade to MS2 (£100) would be better and much cheaper than swapping to OMEX (OMEX 600 is about £550 i think)

Is the onboard logging capability of the MS3 not worth it?
Can it log as efficiently as the laptop and use the files in Megalogviewer?

Why do you need to log the engine data to the ECU? MS1/2 logs to a laptop to aide tuning, but if you have your car tuned properly on a dyno logging is not required after the car has been correctly tuned. It can be useful for fault finding but a blast up the road with the laptop connected does the same job as on board logging.

Unless you make use of the extra functions provided with MS3, i would stick to MS2 and save some money!

On a 4cy engine the only real advantage of MS3 over MS2 is the SD card logging.
This can log much faster than the RS232 connection and it can be veiwed in MSLVV. I have logs where you can see the engine speeding up and slowing down on the compression stroke at idle!!

An MS2 can run a 4cy fully sequentially, so unless you want VVT, 8 EGTs, then I have to agree, MS3 isnt really worth it. Also, dont forget, MS3 can only run hi-Z injectors and the COPs would need built in drivers or youll need a driver box (more expence)

I have an MS3 running my V8 fully sequentially with 8 EGTs and 2 widebands. Its a marvelous ECU and its where all the latest efforts are going to now by the coders. But it is a lot more than MS2 and I personally feel that its not worth it when MS2 can do 99% of an MS3 on a 4cy engine,

i have got a ms3 running fully sequential on a saab turbo engine. its a big jump up from an ms1. fully sequential on the ms3 is a bit smoother than ms2 and you also have the nice features like batch fire startup, semi-sequential batch and fully sequential coil on plug log to sd card, usb connection to laptop. also if you use the ms3x card you dont need to mod the main board unlike the ms2 so its more plug and play if your not confident going off the standard plans. also antilag and variable vvt are on the way for ms3.

Thanks Daxtojeiro and ashg for your comments. That was the info I was looking for.
I may go for MS3 as a project and keep my MS1 as a back up
The fast logging looks like a good feature.
My engine is throttle body injected with siamesed inlet ports so I would need to modify my inlet system to make full use of the sequential functionality but this seems like a possibility.
