E-manage + automatic...

Can anyone elaborate on the limitations of the e-manage when used on an automatic series 1 r33 gts25t.

I have read that you cannot use the ignition control harness on automatic Nissans. Why is this so? Will this be fixed by Greddy in the future?

I assume it is still possible to control the afm and injectors successfully.

If the ignition control remains unusable on an auto, would an exhaust cam timing wheel offer some benefit?

Taken from the sticky e-manage thread in Forced Induction Performance:

Hey guys Just thought I'd share my experience with e-manage. The only significant limitations I've found so far is that you cannot use the ignition control harness on automatics, and the speed limit as previously mentioned.

I've read something about melted coil packs as well. It may have been on the Yahoo e-manage group.

I don't think it affects other ECU's (ie Motec). I think it is just an e-manage issue with auto Nissans. So auto Supras should be OK...

The Dr knows all about this stuff.... Maybe he can elaborate?

I remember Dr Drift saying something that this is one of the limitation of the e-Management with Skyline. That's it doesn't work with the ignition harness or something.

Would be intresting to find out, cause I was thinking of installing the e-Management as well with my auto. No chance with the Power FC and the HKS F-cons with auto. Motec might be too expensive, my mechanics also mention Links Computers but don't know how good they are. Also Unichip but don't know if they will work with auto either.

Damn auto!! hehe :P

Strutto - Thanks for the PM...

Here Goes....

It appears that the automatic's wiring in nissans do in fact read the RPM signal from somwhere (haven't investigated where yet).... This signal going through some extra wiring to the auto control unit causes some minor electrical interference. This interference is picked up when trying to tune the e-manage. I assume this is due to the e-manage being more sensitive than the factory ECU. I am also assuming this is the same reason that neither FC's or FCONV's are available for automatics (maybe link's aren't either)??

My problem so far is that I have only tried tuning e-manage (not fitted by me) on one automatic car which was severly accident damaged by the owner a week after my initial attempt. The car has since been repaired but I think the owner is no longer looking for the extra power.

I have had several suggestions on how to rectify this problem, ranging from resistors inline with certain wires going to the e-manage which have RPM based signals (CAS, IGN, INJ), and to also try and run shielded wiring for the emanage.

All the other ECU's I've seen run shielded wiring right up to the ECU which the e-manage doesn't, so this would be the first place I would look.

Skylineakt - As far as fuel tuning goes the E-Manage is excellent, and a much better option than an SAFC or similar.... Perhaps you would be interested in a discounted supply/install and allow us to research this problem further on your car? Worst case scenario is that you have more power with a perfectly tuned fuel curve... Best case scenario is that we will discover how to maximise the potential of the e-manage for all our skyline brethren the world over???

Doc.

      Can't see that being a thing.

      R34 GTT Central Locking Pains

      By Kinkstaah · Posted

      My fob has never worked, I once attempted to follow the procedure to re-key it, (I have other fobs for the car alarm thing in there). I actually have three of them. Do aftermarket alarms take over the pairing mechanism for central locking? Or do they piggyback off it? I suppose it depends on the system, right? I have four sets of keys/keyfobs. One definitely works, one I think works, one definitely doesn't work, and I have the OEM one that has never worked :p. Is this fixable/workable/whatever? I mean I know it's beyond "just clean it" but how *do* they get synced up?

      It's actually a really weird comparison... the MX5 is on another level and I kinda question this comparison at all. It'd be closer to compare it to a GTI/Golf/Hatch anything that kicks around. NC MX5 with a turbo has the right to go up with and beat the FD RX7 or 180SX or any other JDM hero car. That's the comparison that would really ruffle feathers.

      @MBS206 you need more shed in your life... What sort of car is your mates race car?  Hopefully he returns the favour when you're ready to get cracking on yours! None of my mates are into cars so I don't have to worry about that as a distraction thankfully.  I have enough other distractions so I don't need that one too!  Between working 6 days a week (5 1/2 really so 55 hours or so per week), both kids have basketball almost every week night (including Friday night in Melbourne - 2 hours away), my daughter plays netball as well, my sons footy has started now and I coach his under 14's side as well as I'm on the Footy club committee this year, I ride motorbikes every spare Sunday I can find, plus trying to be some sort of a husband.  Life is a busy little exercise at the moment!  I wish there were 8 or 9 days in a week sometimes!

      Ha ha, that is very true!  I'm too scared to leave it in the position though, it tingles my balls seeing it like that!
