Hi,

I've sent you my .msq file via your email.

For the 1600 RPM thing, do a datalog and send it to me. I'll have a look!

I have a 88 Celica Alltrac with a 93 MR2 3S-GTE engine. I also have MS2, Any help on wiring and maybe a PM would be great. Thanks for the help.

Have you already started on the wiring? Are you using the alltrac or MR2 harness? Or making your own?

Have you gathered the needed diagrams? And what preciously do you need help on?

How's everyone getting on with their ignition maps? I've tuned for leaner than stock AFR at cruise but regardless of timing I can't seem to get sensible fuel economy. My old table further up this thread works fine still but my MPG has gone from (UK) 24-27 around town on the stock ECU to ~19 regardless of anything. Running out of ideas.

If you're talking about city MPG, I would say that TPS/MAP accel enrichment is the main player. Be sure that small change in TPS/MAP do not trigger AE more than needed. About this, I'm now using the EAE and it's working fairly nice. Even with some big changes in MAP, the AFR stay flat. I highly recommend trying to use it.

Do you have some start values for the EAE+celica manifold,or some guidelines ?
Also do you have the stock manifold (not ported,not polished) ? Thanks

You can look at my .msq file here :

http://www.msextra.com/forums/viewtopic ... 17#p275017


Here is a very good thread about EAE :

http://www.msextra.com/forums/viewtopic ... 66#p185966

I cannot explain it better than Ken's post.

It require patience and lot of tuning via very small steps to get it done. But first, you need t0 understand the basic of how each parameter is acting. Read this page of the manual too :

BTW, my manifold isn't ported or polished, it's a stock ST215 one.

Cheers Sam, sorry for missing this, the forum doesnt email me any more for some reason so hadn't spotted your reply, unfortunately you're running a completely different version of the MS to me - no EAE on MS1, the closest it gets is RPM based AE, which I'm using, with a fairly high trigger thresh, it doesnt trigger with fairly normal changes in cruise speed, it only triggers with stabbing the throttle.

So what are you guys doing for knock control?

It seems the J&S Safeguard is the method of choice, but it would be nice if there was a decent/reliable knock sensor package that could be integrated with a MS3.

Any ideas?

Personally I've just tuned for the worst fuel and given a little leeway, while listening to the knock sensor with an amp, no active knock control.

This needs a friendly pump. Anyone using the the MSPNP on an alltrac with stock everything? Anyone try the knock board?

I ask cause I am considering try to use the MSPNP on my trac in the near future and while I have a stock harness I can hack up a little, I would like to keep costs down and just use stock ignition instead of getting COP, trigger wheel, etc.

So I'm VERY new to Megasquirt but I had a question about the 24-1 crank sensor issues. I seem to remember reading something recently about the issue being fixed...is that true? I"m looking at doing a DIYPNP MS2 for my gen 3 swap and want to make sure I understand EVERYTHING before I spend my money on it. I'm not looking for anything crazy right now, I just want to tune my engine to run a bit better since it's currently running pig rich!

Mega ultra thread resurrection!

I just got a DIYAutoTune DIYPNP running on my ST165 if anyone is interested.
