I have a '89 Turbo 2 with a mild street port (2500mi on motor), 720cc secondaries, fmic, t3/t4 hybrid turbo, and so on. Factory coils/igniters by the way. I drive this thing daily with the factory ecu with no prob. I just got my wolf plugin a couple of weeks ago and tried to start the car. well after playing with it i found out i am not getting any spark from the trailing plugs. with my factory ecu everything is ok. as soon as i hook up the wolf and try to tinker with it nothing. The car is ready to crank easily but the only thing holding me back is the spark issue. Any ideas?? i hope its not the ecu.. =(

i think someone else just recently had this problem.

 

Yea i think i know who ur talking about nyt. That guy had an older version of wolf and it was a different scenario. Chris at wolf is helping me out with the situation and i think we figured out wat was happening. We'll see tomorrow nite.

 

hmmmm let us know what you find out......

 

Unless the plugins are different to the other V4 Wolfs I would guess that it doesn't support Trailing select. I had the same problem with mine and went to direct fire to solve the problem. The old version3 worked OK with these coils and ignitors.

hmmm, you sure you ignition sequence is set to:
0 0 1 0 255 255 1 0 1 0 255 255 0 1 0 0 0 0

 

ok here's wat happened. when i first installed wolf i tried cranking it and nothing happened. i scanned through the handbook and handcotroller and just looked over the settings. well later when i found out i had not spark from the trailing plugs i changed the input trigger settings. I tried all 3 options to see if anything changed with the spark issue. After speaking with Chris from wolfusa, he told me i that by changing the settings, that i had smoked the factory software that comes with the ecu. To fix that, i had to upload another base map. After loading the base map the aus guys sent me the car crank instantley. Now i have leading 1 and 2 firing, trailing 1 firing, but not trailing 2. A jumper wire is suppose to be included with the wolf plugin kit to connect the leading and trailing coil packs together becuase of the tailing select. well i didnt get a jumper wire with my kit. the leading and trailing coil packs have a small wire just dangling out there with a female pigtail. your suppose to connect the leading to trailing for the trailing select. with out being jumped, i have not t2 spark and my tach only shows slightly above 0 rpm. after connecting the two, i still have no t2 spark, but my tach reads correctly. ive tried 6 different coil packs and i get the same thing. So now i am waiting for a call from Chris who is waiting on an e-mail from the aus boys to see wats up...lol...i hope you guys kinda understood that cuz i am still learning about stand alones and tuning ect...but u learn a lot though.

so, you mean we need to add a wire to the trailing coils from the ignitor??

i lost you..the jumper wire must go from L1 to T2 right???

 

No RacerNo39 is right and what a simple solution. If you use the leading coil timing pulse to switch the trailing select then the trailing signal should work with the standard coilpack.(I could have done with that info 12 months ago!) The only problem I see is that as long as the right trailing coil fires first then the timing would be correct every time. My guess is that the trailing signal is missing or you have a hole in the trailing signal lead that is causing your trailing ignition problems.

Michael Smith

 

it sounds like he hooked up the leading to the tach wire that dangles from the trailing pack. hence why he has tach, but still no spark on t2.

the toggle will not be hanging as far as i know. it will be one of the wires run to the igniter. if you need i can post the FSM page for it later.

 

correct nyt... so wat ur saying is, the reason my tach is reading correctly is when i do install the jumper wire is cuz i have it pluged into the tach wire. so where do i need the jumper wire to go to get spark? to a wire from the igniter? whats the fsm page? im bad with abbreviations

 

ok, i just got an e-mail from chris at wolf usa and said that there was an issue with the base map he sent me. The owner from aus sent him another base map to send to me and should cure the no spark issue. wat it is i dont know, he did not mention it in the e-mail. so after i get off work tomorrow im going to run up to my shop and see wat happens with this new map. i will post updates tomorrow.

 

good luck, let us know how it goes.

 

i didn't get to it today but i will try the new map tomorrow and see wat happens. the only thing i need to know is how to post maps.

 

ok here's the new base map the aus guys sent me. the crank up rite away and i now have spark from my t2 coil. the only problem i have now is when i connect the jumper wire for my tach to work, the leading and trailing coil packs get very hot. ill have to call chris at wolf usa monday and see if that is normal or should i be in worry.

 

with the plugin the tacho should work without touching anything.
Michael Smith

 

so to get spark on your trailing, is anything special hooked up to it?

 

no nty. i guess they screwed up something in the first map. i looked through to see wat has changed but i couldnt find anything. i dont know what settings they changed to get spark to t2. but once i uploaded that new map i had spark. but now i dont have a tach unless i use the jumper wire like i said b4. but when i do that my coil packs get really hot, and they shouldnt. so im gonna crank my car and let it warm up and see if the coil packs get hot without the packs being connected. so one prob to the next. lol.

oh by the way, i test drove it and was looking at some telemetry also on the test drive. this baby is gonna be bad ***. i turned on the boost control and was boosting 15 psi and it pulled awesome, and thats untuned of course. coming back, we did a quick pull and the boost rocketed to 20 psi and then BAM. my ic pipe going to the turbo had pop out. i guess i didnt tighten down my clamps hard enough. it was scary for a moment, i thought the bov blew up or something blew up anyway.

 

On the version 4's there is a dedicated wire to drive the tacho it is purple in colour and is in the wiring going to the ignition coils. It is on pin 17 of the ECU (standard generic V4) Usually the tacho output is derived from the ignitor on the standard S4 engine I don't know about the S5 ignitors. When I had a version 3 wolf I didn't need to do anything with my tacho it worked off the ignitor.
Michael Smith

 

yeah the tach works off the trailing ignitor if i recall correctly. I had to hook the tach output up to it since im not using the tII igniters tho.

I'm curious how the little harness is setup to connect to the toggle and what output theyre using.

im flipping through the manual now to see if i can figure out how its being done but not finding anything.

in the posted map i see:

ign1: 0 offset, 0 skip, 0 output mode (not sure where this goes)
ign2: 0 offset, 0 skip, 1 output mode (this goes to leading)
ign3: 1 offset, 1 skip, 0 output mode (not sure where this goes)

Output mode 1 means the next event will be a trailing event.

(pardon me im kind of thinking while im typing here)

in a standard map with independent trailing coils i have:

ign1: 0 offset, 1 skip, 0 output mode (T1)
ign2: 0 offset, 0 skip, 1 output mode (L1/L2)
ign3: 1 offset, 1 skip, 0 output mode (T2)

the only difference i see in this map, is that T1 is firing every time.

so you have firing sequence like this:

1. L
2. IGN1 (as trailing event)
3. L
4. IGN1/IGN3 (as trailing event)
repeat

now ignition 3 might not be wired up to anything.

now i dont see how exactly this could be wired up to work, but i might just be missing something.

if the leading is being used as a toggle, its entirely possible the trailing spark would be firing as a waste spark 50% of the time you start the car.

ill have to think more on this later.... can you post the original map that had the problem with no t2 spark please? It might shed some insight on this for me

 

now that i think of it, if wolf waits to see the home trigger to throw spark, itll always start at the beginning of the phase. which means ign3 probably isnt used, and l1 signal is jumpered to the toggle.
