Will MS-II run a SRT4 motor?

Well MS-II run a SRT4 motor? I am installing an SRT4 motor in an Omni and was wanting to use MS-II. Will it read the stock crank timing wheel?

easy now!!! not everyone at once.

I found this......

I am not an expert is the reason I have not already answered. As long as you have a crankshaft position indicator that is compatible with MS-II, I do not understand why you cannot make it work. You may have to build a wiring harness as I did. On my project I was fortunate that the stock sensor works fine. Let's wait for some of the Dodge experts.

Cheers,

dodgez,

In general, the reason people don't get repsonses to their posts is that they have not provided enough info for someone who knows about MegaSquirt to reply to.

For example, asking, "Will it read the stock crank timing wheel?" only helps if we know if it's a VR or Hall sensor, how many teeth it has, how many are missing, and what sort of pattern there is between the teeth and missing teeth.

Without that information, only someone familiar with your engine can answer, and that really narrows the field for less common engines.

So you need to do a little homework, and tell us more about the crank wheel and other aspects of this engine (like ignition), then you'll get more help.

Lance.

should be a 34-2 wheel. and that means it should work with MSII code. dont' think it'll work with MS-n-E neon code tho. good luck!

dodgez,

I did a search for SRT-4 and came up with a user named grawill who uses MSnS-E on an SRT motor. You might PM him.

Jason,

MSII has NO missing tooth wheel decoder (yet). MSnS-E does, and would likely support this configuration.

my (very large!) mistake! i've gotten them confused, been reading lots of different stuff. some that hasn't been implemented yet. i mistakenly thought it was.:

http://www.msefi.com/viewtopic.php?t=15682
http://www.msefi.com/viewtopic.php?t=15779

in that case, don't bother with msnE and put an EDIS wheel on your crank puley and then run COP or wasted spark from the EDIS. or wait for the missing tooth support in MSII out. you can leave the stock wheel in and toss the EDIS stuff when support is added. another, initially cheaper option(teh TD way!) would be to run MSNSE on an MS1. upgrde to an ms2 when/if there's support for the missing tooth. then no real hardware changes. either way you should use the v3 board.

another option would be to wait for the microsquirt and in the meantime brush up on coding and write some software for the GPIO board if you can. :P

Garwill has an SRT turbo on his 1st gen neon. A little confusion there.

Steve @ rs-autosport.com and I are working on the NGC decoder for MSnS-E. BTW, NGC = Next Generation Controler found in all 03+ chryslers including SRT-4. So far its reading RPM off the factory SRT crank trigger. Spark control should work soon.

Hopefully once we get code that works 100% James will add it to the MSnS-E code base.

Once someone releases wasted spark code for MS-II I'll be happy to take a stab at porting the NGC and Neon crank decoders to C.

I've thought about this also.. There is a lot of "patch" work going on for the high powered SRTs running aftermarket turbos.

The only real problem that I see, outside of ignition as mentioned above, is emissions... Lots of states expect these cars to be OBD-II compliant and if they're not, they FAIL inspection regardless of acutal emissions numbers.

I'm running a Mopar Stage-2 computer in my SRT. They use a part of that computer normally reserved for automatic transmission control to actuate functions of the intercooler sprayer. It throws codes on OBD-II diagnostic (auto transmission related). As such, it fails emissions... Mopar says "not for use in emissions controlled vehicles" - and won't support it..

I'd hate to have a similar problem with megasquirt.... Stupid law - emissions should be based on EMISSIONS, not OBD-II compliance.

It's not going to be OBD-II legal. There's no way around that. You'll have to return it to stock ECU control to pass the emissions test.

The other systems (hydra, AEM, etc) will have the same problem...
