hopin u guys can help us out.
just set my wolf up, and after setting all the trigger seq. parameters, i am getting a lot of signal errors on the software.

i have a map that i have used for my setup, which is supposed to be the same, which i hope someone can edit, if possible. im running standard 6 port 86 with standard injection. i adjusted the trigger seq. to suite the way i installed the cas.

i have 4 ignitor /4 coils(appropriately heatsinked), wired to run waste spark so ign1 to t1..ign2 to both L1,L2....ign3 to t2.

my cas is wired as per the wolf dealer tech setting 1, for rising edge and i know my polaritys are correct to suite.

the trigger 1 and 2 pulse reasonably only on the low voltage setting, very low, doesnt seem to work very well? i have set my ref. pickup gap to 0.1mm as specified by wolf.

i have strong earth and have powered the e.c.u with all correct relays, and strong ptv.
its quite strange, as the rpm can jump on cranking, suggesting that there is a problem with the cas settings.

do i need to zero my ignition maps?
where can the system be letting me down? i have tryed a mates cas which immediately made a difference in trigger response but logged error codes still, but atleast did not throw a constant red error block.

does anybody have a map that will runs the same ignition as mine?
iv had an auto elec mate run over the system, as well as i have, and no problems with wiring. i attempted setting the seq, as per the dealer techs, but i get stuck with the settings for waste spark coming from 3 ign. outs.

any info/help would be great..cheers

Hi S1rx try this. Also you need to only one end of the shield grounded and that should be at the ECU. What style if CAS are you using and does it have all its teeth. I have a modified CAS thats why I ask. I bumped up the pickup voltage to very low. O yes also keep the wire well away from the sparkplug leads and coils I ran mine back along the centre of the engine and in my case behind the soleniod bank where the standard wiring harness goes.

thanks michael,
i am running only standard cas so 24teeth and the 2 tooth sync. i have talked to steve from wolf, and he suggested the reluctor signal box, available from wolf directly, to improve the quality for the signal...i have confirmed the setup with regards to my trigger and ignition seq as correct.
i have tried very low setting on my sensor voltage, but to no avail. i actually get less errors logged on the low setting, although my rpm still jumps occasionally on the rpm display on the software. i have disconnected all alternator wiring etc, to get rid of any interference, and yes both trigger wires are run seperate to loom, and also away from coils, ignitors and leads. i am barely getting any output from the wolf to the coils, and obviously from there to the leads/plugs.
u say - the shielded cable on the e.c.u side needs grounding at the e.c.u side only.... the shield cable runs into pin 27 of the e.c.u.. i havent grounded the other side of the cable(on the engine side of the cable) only connected wires to cas...the shield runs right up to the connection on the cas. red and green to earth. white to br/white trace .. white/blk trace to yellow/wh trace...so shouldnt be a problem there (set to rising edge as req).
i know of a couple of people that run only standard cas and successfully started the car with these settings, and without the use of the reluctor box.
wat else do you suggest could be the problem michael? i guess the next question is should i bite the bullet and order the box? or just modify the cas.

thanks for the help so far..

If you look carefully at the cable that goes to the CAS you will notice that on the very inside of the rubber is a shiney metal if this touches the CAS case then you will have signal problems. Tape the end cable just to make sure. It is possible that one of you pickups has lost a few turns..this happens sometimes and say 10 turns short out you may lose 10% of your voltage which isn't much at cranking anyway. If you get a copy of a V3 manual it also has a Electrical Mod to your CAS and I currently run this mod on my V4 Wolf. If you want more detail I will post it here.

more detail on the CAS mod, just because i figure i should do it when i install my wolf v4. i hear about it but dunno why its better or what exactly to do.

sorry to not verify my model. its ver4 last firmare bfor plus...ok. i have checked the cable. no problems, as it finishes short of the cas. and i have taped the end to ensure it all.
im sure i can get the manual off the wolf site, save havin to post it.
i have a good cas as i tested a couple and this has nice strong +ve/-ve signal thr multi-meter. from both sync and ref. pickups. i will carry out the elec. mod as suggested.

kevin i would suggest just purchasing a reluctor box through wolf at 88 buks its a fairly reasonable price that ensures good signal...i believe it converts the signal backto a square wave?? well thats wat other boxes do i believe.. and still allows use of standard cas.


i will post regarding success of elec. mod. cheers.

Her it is..
