30-1 tooth wheel with cherry hall effect sensor

Recommended Posts

Going back a few posts, I hope you didn't just plug in the numbers I posted for my wheel. They would only work if your missing tooth was exactly the same as my wheel (highly unlikely).

 

MS will pick up the RPM no problem since you told it's a 30-1 wheel (30 teeth, gap -1) but the spark will be all crazy because the coil firing positions are wrong.

I dialed in my tooth seperation but still no dice

I think its in the config of the coils to plugs

 

thanks Lancevance: that helped for sure

 

Been swamped at work this week so may give her some love this weekend

 

I also might buy an FR-S tomorrow, it may or may not be related to my car troubles haha  :wink:

Ok let me try to get this all in one post, I have some time tonight to go through all my notes

 

attached is a picture of my last routing of my coils to plug set up

 

also i attached how i wired the coil to relay board and coil drivers to the MS pcb

 

the missing tooth @ TDC is 18

 

Last i tried i had my trigger settings at

 

A Pos      13

    Return 17

B Pos       23

     Return 27

C Pos       3

    Return  7

 

I tried moving them around in incriments of one but could not find the right pattern

 

The version of my MS is MSnS-Extra Format 029q

 

any ideas guys? Sorry for taking so long the FR-S is a nice little car so havent been thinking about the datsun much.

I am excited to feel real power again with all the upgrades i just did :-)

Your wheel settings look fine, but your coil wiring is still screwy. The coils should be paired 1+6, 2+5, 3+4. It looks like you have plug wires on 1+4, 2+6, 3+5.

 

I modified DIY's picture for that coil and how yours is mounted upside down in your car, it should look like this:

That's front to back ABC.

so i tried to start it with the same resault

 

It looks like i already had the plug wire routed the right way  A 1,6 B 2,5 C 3,4

 

Here are some pics of my relay board wiring to coil

 

the green wire is switched power

 

Does this look right?

On second thought, I might be leading you astray here. My ignitors aren't mounted on the MS board, they're inside a GM DIS coilpack where the GM ignitors used to be. MS just outputs a spark logic signal, not the coil grounds. I guess how you wire the output of your ignitors is up to you, if they're on SP2, 3, 4.

Im going through my notes right now, Looks like everything is wired up right

 

Relay output          MS pin out

 

S1==============25                               

S2==============27

S3==============29

S4==============31

S5==============36

 

If everything is right here then ill have to double/triple check my missing tooth to TDC but im pretty sure thats on as well

Then back to the Trigger settings

 Relay Board to coils wires

 

Current                 Correct

 

S3 RED               S5 RED

S4 BLUE             S3 BLUE

well i swapped the wires and it seamed to be close, just sounds like the timing is off but it still does not run

I think its all settings in MS now 

Ive only had small amounts of time to get tests in but ill look at the trigger wheel again and dive into the trigger settings again

 

it may be time for a degree wheel, Once i get it set ill make a summery of all my settings and hook ups :-)

 

Silver lining is that the wideband seams to have stop having error8 :-)   Disconnecting the battery for a few weeks must have re-set it
