Here are my settings, what is wrong? I get this error message."Config error with spark output or decoder trigger settings" Will post more later.

I'll take a look later when I'm home from work.

First of all, in spark settings, you have spark output inverted. It shouldn't be
Second, you have staged injection turned off... it should be on.
Your dwell is too high, you shouldn't need more than 2.6 ms for running.
The cause of your error is that you have rotary trailing turned off.
Your rotary split table that you have set up is also going to cause problems... the bottom of the table is set to 21 degrees. That will turn off trailing.


The fact that you have 3 spark outputs set but rotary trailing is not turned on is what caused your error.

This is all new to me, but I am learning. I found out a long time ago, if you are having problems with something; go to an expert, one of the best.
Thanks greatly

I redid the settings, but now no spark, the tack doesn't register. It's late I'll work on it tomorrow when I get home. The fuel pump stopped turning off-on.
thanks

No spark is likely a wiring problem.

57bronco

I guess I shouldn't have said no spark, I didn't have time to check, it was late and I was tired. I ment that I had no RPM showing on my tach or on the megatune as I was turning the engine over.
thanks

I changed the settings and now it hits and will start if I hold the throttle to the floor may be a little fludded by now. This is my new settings. I ran out of time again, I've got like 10 projects going at the same time, getting spread a little thin. But there is starting to be a little light at the end of the tunnel.
She will live again!
thanks.

57bronco

Well I re-did my grounds and replaced the starter with a newly rebuilt one. I'm going to run and get some new plugs, but here is my latest settings. Could someone look them over and give me their input?

Any reason your tooth counts don't match the FAQ? Yours are 1,3,7,9 while FAQ shows 11,1,5,7. Other things to check: Be sure you have TSEL jumpered to VROUTINV on the board, and VR sensor polarity matching that shown in the FAQ. Check timing while cranking. Be sure to put the strobe pickup on the leading coil wire, as the trailing don't fire during crank.

Did you mention your hardware setup anywhere? Is this a purchased box, or did you build, and modify it for the rotary yourself? You have second trigger set, so I assume there is either an LM1815 circuit build in the proto area of the V3 board,or you've build a daughterboard to suit.

57bronco

I know my tooth count should be 11,1,5,7, but she won't start unless I have it set to 1,3,7,9. It will run but not very well. Before the ms it ran perfectly. As soon as I find my timing light, I think my son may have loaned it out, I am going to check the timing. This box has been tested on another s4 n/a, and it ran. I kinda screwed up and re-flashed the board; long story.

Odd that, what's the trigger angle set to when you are using 11,1,5,7?

I believe it should be set to 65 with a cranking timing of 5 degrees.

You should really go back to the other settings and check your timing.



With the settings you have now, you would need to restab the CAS so that tooth #3 after the G tooth is lined up with the Ne sensor... it would run fine with those settings.

I checked the CAS and with the timing mark(0ne on the drivers side) lined up with the pin, I have the third tooth (clockwise, including the tooth with dimple) lines up with the pickup.
David

muythaibxr

OK, and you said it runs, but just not that well... so next time you start it, try tinkering with the fuel table and such... let it warm up first of course, and do check your timing once you get it running decent.

57bronco

I'm going outside to try some adjustments, let you know what happens later.

David

57bronco

I stabbed the CAS as the service manual said to, with the marks on the side of the housing and the dimple on the lower gear. I tried the 11,1,5,7, again, with no luck; I set it back to 1,3,7,9, started up, just doesn’t run below 1500 rpm's. I set to 65, and it ran a little better. She seems to be running really rich.

David

muythaibxr

OK, then when you stabbed it, you probably got it a tooth off.

when I'm stabbing the CAS, I always take the top off of the CAS, and stab it while holding the wheel. once stabbed properly the sensor should be halfway between teeth 1 and 2.

With the CAS stabbed that way, it should run fine with 11,1,5,7 settings and 65 deg trigger angle.

If you want to just keep the settings you're using, just start it up, and set the MS fixed angle to -5, and use a timing light to set the timing by turning the CAS. If it won't stay running with the -5 setting, turn the CAS to advance the timing a bit, and start it back up, then using the light, set the timing by turning the CAS.

Once you get the timing right I'm sure it'll run. We just started up our test car on the exact settings I sent you today without problems.

Ken

57bronco

I stabbed the CAS with the cover off and held with my thumb, so not to move and it is half way between 1 and 2. I haven’t been able to set the timing yet maybe by Wednesday, I teach Monday and Tuesday nights 5:30-10:30. I'll try -5 instead of -10 too.
David

muythaibxr

-5 just sets the base timing so you can actually use a timing light to set it.

Odd that you have the CAS stabbed right, and the 11,1,5,7 settings don't work. Like I said, I just tried those today and it worked fine.

With the 11,1,5,7 settings, did you change the cranking timing to 5 degrees?

with 11,1,5,7 also try setting cranking settings to time-based, and the timing to 0.

Or you can just leave the 1,3,7,9 settings with a 60 degree trigger angle, trigger-return crank timing, and 0 degrees for that, and just set -5 base timing, and turn the CAS until you get proper timing with the timing light.

When done set the fixed angle back to -10 so it'll use the map for timing.

Ken

57bronco

I don't under stand why it is doing this, I'm going to keep at it until I figure it out.


I was wondering if s4 and s5 use the same CAS? My s4 and both of my s5's have the same part# CAS, but the wiring is different.


David

muythaibxr

I believe their CASs are the same.

Anyway, let me know how it goes.

This is two of my datalogs
David

Well, I've gone through and replaced all the grounds, ran new ones all over, even the ones from the MS to the engine. I replaced the starter, alternator and the cables too them and added an extra one from engine to body. My rx7 will only crank on the 1,3,7,9 settings, if I try 11, 1, 5, 7 she will not make it to 300 rpm’s w/1,3,7,9 I get in the 400 rpm range but never steady. She doesn’t run very good on the 1, 3, 7, 9, setting. I replaced the CAS, twice, from running cars.

Can the timing pulley be installed incorrectly, this car has 200k mi. on it and only about 5k belong to me, so I don’t know what has been don in the past.

Any help would be greatly appreciated, I’ll try anything, I really want this to work.
Thanks,
David

muythaibxr

with 1,3,7,9, trigger angle should be 60 degrees.

Set the fixed angle to -5, and align the CAS using a timing light so that you're lined up with the yellow mark. Then set the timing to -10.

From there if it doesn't run well, you just need to tune.

Ken

muythaibxr

hrmm, just looked at your logs... you've definitely got a noise problem. A really bad one too... I'd almost suspect the diode in your alternator or something like that...

Could you run without your alternator for a few minutes, and log it?

Also, Just to be sure, could you post your latest msq so I can take a look?

If necessary, I might have you call me to help you adjust some other things to see if they make a difference.

If you "reran" your grounds... that might not be good, All you really want to do is clean up the stock grounds.
