I just installed my E6X with the help of two experienced members, Nik, and IAN. Before we got the car running the timing was set at 70, and we could find the timing marks on the main pulley, now after we have had the car running and driving, we cannot find the marks with the timing light.

When we lock or unlock the timing, there is a minimal change in the sound of the car, but it still won't rev passed 2k RPM, has MAJOR ignition break up (sounds like the 2 Step is engaged.) Could the leading coil/ignitor degrade that fast? The stock trailing plugs in the leading were so worn that they were basically rendered useless.

Could the leading coil be firing so far out of time that the light won't pick up the marks on the main pulley? Could there be another more obvious or obscure problem that we aren't thinking of?

We are using the stock Hitman map.

We have restabbed the CAS multiple times, using the Hitman method and the stock method.

Any help would be greatly appreciated.

Thanks,

Kevin.

How do you have it wired up, what ignition components are you using? how do you have it setup? Did you zero the timing properly?

Wiring:
Ignition Output 1 (light green) to Leading Coils (Pink)
Ignition Output 2 (white/black) to Trailing Coils (Pink)
Auxiliary Output (green/black) to Ignition Toggle (white)

Software Setup:
Spark Type – Distributor
Charge Time – 3.5ms
Spark Edge – Falling
Auxiliary Output – Ignition Toggle

I think we had it set 70° and teeth 24 offset 11 stabbing stock method.
Stock coils stock wires. (stockwires after we found the accel wires to be only 100ohm a foot. the fsm says wires should be in the 8kohm's.)

Basically no different setup then my old e6k setup.

The first crank and start up was without touching anything. Base map and boom the timing marks lined up almost instantly. Drove the car around fine without boost. Then over a few km's you can hear the motor change in sound. Checked timing for kicks and we did not get anything from the timing gun. Changed plugs and wires and we had timing again but we could not get the timing set. (See nismo comments above)


I'm stumped. Halwin software is weird. That stupid download map each time you switch the ignition is time consuming. I guess its that way so that you are on the correct map or something?

Anyhow we rang out the connectors to the haltech harness. Measured the coils (like that proves alot) and checked the fuel injectors. Only thing I could think of is bad coil or weird haltech.

When we first finished the wiring we zeroed the timing with the settings outined by IAN, 24/11/70. The yellow mark lined up to the pin with no fuss(with timing lock on).

The next day the car started and drove well. After fixing some throttle cable sticking issues, and installing a wb02 to do some tuning, we went to get some gas. On the drive there the car still drove fine, I got him to add a bit of load and to hit some light boost, under these conditions the car started bucking/misfiring and AFR went to 20. So we filled up, went home and confirmed the injectors were wired correctly(car still drove fine under vacuum). Once this was confirmed we went for another drive, and I started to tune the vac ranges. There were some slight pickup issues (jumps to 16kprm) so I decreased the gains and turned motronic mode off and this fixed the problem. However, tuning the higher rpm(> 4000) vac ranges proved to yield the same bucking problem, but no pickup issues. I took several datalgs throughout the day after this and none of them showed any trigger problems, despite very rough running. At this point we pulled the plugs and wires and found those very low resistance aftermarket wires. Also the leading stock plugs showed very abnormal wear of the 4 grounding electrodes. I think kevin can get a picture of this.

We went back to stock plug wires and new plugs, but everything went downhill from there, as the timing marks no longer synced up and nothing we tried was able to get them sync again(even though nothing changed in terms of haltech setup, or cas position). We also disconnected the trailing coil at the coil to rule out any crossfiring/trailing ign issues.

What was the timing lock value you used, -5 i hope?

Tell me about your trigger settings, what edge did you use, did you make sure you connected the positive and negative terminals on the reluctors properly the input trigger wires? Also, what gain are you using and filter level, you said you turned the filter off? does that mean zero?

Also, id ask, what kind of a fuel system do you have? what pump, fuel filter and injectors?

nik

Timing lock to -5.

Trigger wired as follows: http://www.k2rd.com/haltech/drawings/T01.pdf

Falling edge on both, gains set to 0. (gains were 2 and this caused pickup issues) In the dos software there is an option that says motronic mode, that is either on or off. I turned it off, as this has helped before in my experience. I believe the equivalent settings in halwin are: reluctor gains=0, motronic filter=2

I believe it's an FD pump, stock filter, 550 prim and 720 sec. Stock fuel setup (plumbing).

Ok, sounds good so far, when you say stock fuel filter you didnt mean original one from 80's right? you mean just a stock replacement? ever think about cleaning your tank? There's a lot of muck accumulated in them over the years, believe me, i've cleaned a couple, its no picnic, if you do clean it, also send your injectors to get cleaned up. Ive seen cars go from normal to bad to worst to not running because of dirty injectors, thats why i asked about these things.

Other than that, i cant think of anything, but i know its not ECU related.

It looked like a new fuel filter.

We still think it may be a coil. But no spare one around.

(Maybe I can send you a spare one nismo on loan?)

Ive got a set of good coils if you need them. Just let me know Nismo....

Thats a very weird problem, I hope I don't run into something like that firing up the 1/2 bridge on the E6X in a few weeks

Wish me luck too. Gonna be wiring mine friday! (E8)

I haven't had the net in FOREVER!!!

The filter was replaced last fall, the intake sock was replaced, I have a brand new Walbro waiting to go in. I have a Coil in the mail as we speak.

Are you guys still stuck on this?

I'm posting under my brothers account. (Its Ian)

Anyhow as far as I know nothing has been done yet. Hopefully new coil in it this weekend and we will see.

nik

Yep definately still stuck.
Kevin hasn't tried anything yet as it was too cold last weekend. Ian, remember the wire for the leading coil trigger that didn't look like it was the right color, but was the only one that made sense? I told him to double check continuity to make sure it's going to the right pin on the ecu.

Ok guys, I installed the new coil, is will free rev up to 5k fine, but now I have trigger problems, again, I will take a peak at this tomorrow; assuming the weather holds out.

IAN

IF that was the wrong wire to begin with I would figure that we would not have it running the first time? It sounds like since he replaced the coil and now that it revs it might work

I will be trying my e8 today. Gave up on finding an older computer and went out and bought a hap pavilion dv2000 laptop. Dam it does not take long to spend money. I think the rx7 commands all of it!

Keep us posted nismo........

nik

I talked to him last night, he did double check the wire. It's quite strange that haltech would change their wire color like that.

At least trigger problems can be dealt with, so he should be up and running after some tinkering.

I've been dumping boatloads of money too, just bought a set of race brake pads, and those funky adjustable camber links for the rear. Good luck with the e8 ian!

IAN

iTrader: (3)

Yup. My E8 has some differences as well. Seems like they copied and pasted the manuals and schematics and may have got confused in the process

O ya. Stupid windows vista and USB to DP9 does not work! At least I have not been able to get it to work.

NISMO! Does it work yet!

It's pouring outside right now, tomorrow Brain is coming over and we are going to check timing and fix the trigger issues.

Well, all seems well drove it around town in vac. No jumps in RPM, seems really good, just need the WB now, but I had to move the magnets on the CAS, and needed a new coil.

Nice nismo - now tune tune tune.............and then tune

Yup, thats the plan, the WB should be here this week, and now I need to borrow a friend to drive the sumbitch.
