skylineakt Posted April 21, 2004 Share Posted April 21, 2004 I remember 666Dan last time only used the injector harness and not the ignition, therefore he had no problem with the coil pack. I was under the impression that the coil pack only goes with the ignition harness installed. I think the fuel control is fine. I also have heared from the Yahoo group that the 1.36 firmware have corrected this problem. Is this the new firmare you are talking about Abo Bob? Last time I spoke to Dr_Drift, he mentioned something about signals interference somewhere from the ignition harness to the auto ecu and this was what causing the problem. I think that's what he said?

666DAN Posted May 22, 2004 Share Posted May 22, 2004 Hey guys, no I'm still not using the ignition harness. BTW just for your information, GReddy are releasing car specific harnesses that just plug in, meaning no soldering required for the ignition and injector harness, as it's a premade unit that goes between the ECU and factory harness.

Sydneykid Posted May 22, 2004 Share Posted May 22, 2004 I just don't understand why it could be a problem to use fuel control but not ignition control. Heaps of people use SAFC's on autos don't they? I was sure I answered this a few posts ago ................ The big claim for e-manage is that they work for autos in piggy back with the standard ECU. This is OK for fuel, but the auto shift problem with ignition timing optimisation seems to have been ignored, or maybe it is simply too hard to program. Yep, thought I did. Maybe further explanation is required. In the autos on gear changes the ecu retards the ignition, this both smooths out the gearchange and lightens the torque loading on the gearbox. If you put an ignition interceptor (e-manage) between the ecu and the igniters this means that the ignition won't be retarded on gear changes. So you will get flaring and damage to the gearbox over time. In order to work on autos, the e-manage would have to have some extra logic in the software that worked out that a gearchange was happening. Then it would allow the ignition signal from the ecu to pass through without changing it. Since Apexi haven't bothered (and/or been able) to program this logic into Power FC's (no PFC's for autos) I don't see it happening for e-manage any time soon. But maybe I am just being pessimistic. I hope so, ‘cause the Stagea will be here in 2 weeks.

BHDave Posted May 25, 2004 Share Posted May 25, 2004 Just thinking out loud. As the emanage has no cas input it is really ony dependent on intercepting the outgoing signal from the ecu and delaying/advancing that (i assume to advance it actually is delaying the signal by almost one cycle). So when the auto shifts the stock ecu will retard the timing to waht it normally would plus the amount of advance the emanage is putting in so the timing is still being retarded to a certain extent. Or no? Link to comment https://www.sau.com.au/forums/topic/11234-what-is-the-greddy-e-manage/page/6/#findComment-856642 Share on other sites More sharing options...

Or no? Could be wrong, but I think not. I don't believe the E-manage adds X amount (of retard) to the standard ignition timing (as varied by rpm of course). I think it chooses the timing all on its own, as per the tuners input. Otherwise you could only have retarded timing, not advanced, as it wouldn't know when to fire because the ecu wouldn't have told it yet. Did that make sense?

Thats what i mean by firing late enough so it's actually early for the next firing stroke. Say when you start the car piston 1 is on the firing stroke, ecu sends signal to fire the sparkplug but emanage intercepts it and does not send it until the next firing stroke on cylinder 1 but slightly earlier in the stroke so its effectively advanced. It's about the only way i can think of that the emanage can advance the timing because you are only adding advance to the standard timing, not re writing the entire ignition map. Either that or it is using the signal of the first cylinder that fires to adjsut the advance on the next one that fires. Trust actually state an error of +/-1 degree in their manual for ignition timing which i assume is because it is not using a cas but using the firing signal from the ecu as it's input. This is why i think it should still be retarding on gear chang in autos. Or i'm completely wrong about the whole thing and it's actually really simple.

mambastu Posted June 13, 2004 Share Posted June 13, 2004 Hi all, Been running an E-manage on a RB25DET for a couple of months without any problems. Got round to wiring in the ignition harness today and the engine runs fine, no E-manage fault codes but the ECU flashes 21 which is ignition related I believe. Tested for fault codes prior to fitting the harness and it read 55 - all clear. Funnily enough I got this code on my CA after fitting the ignition harness too. Does anybody else get the error code when using the ignition harness ? Also is anybody using the new add on detonation sensor harness for the e-manage ?

666DAN Posted June 30, 2004 Share Posted June 30, 2004 OK guys read something interesting relating to the use of the e-manage on the RX-8 apparently the OEM coils get fried by the e-manage as well...this can be countered by using what looks like a zener diode setup....see the link below. It prevents the continuous powering of the coil-pack.....so only the peak signal voltage will pass through the diode (firing signal)...the holding voltage is below that of the diode trigger so doesn't pass through and put the coil under continous load. The theory seems sound to me. http://www.rx8club.com/showthread.php?s=&t...&threadid=17055 Link to comment https://www.sau.com.au/forums/topic/11234-what-is-the-greddy-e-manage/page/6/#findComment-914566 Share on other sites More sharing options...
