i have been doing alot of looking around on the forum about us auto guys looking for an aftermaket ecu instead of piggy back option. as everybody has found out nissan had software installed controlling ignition retard on upshifts to save the transmission from WOT and heavy torque gear changes. there are a few ecu's out there (http://www.motec.com/products/ecu/control.htm#M600) that provide ignition cut on upshifts but require a clutch pedal to activate a micro switch to signal the ecu to cut the ignition (also know as a flat shift module) from reading a few of the posts on here it seems like a few of u boys are alot more elctronicly minded than i am and should be able to find the trigger wire form the standard AUTO ecu that triggers the standard ENGINE ecu to do it's retard thingy and use this instead of a clutch opperated microswitch. now i know it wont be as perfect as the standard software due to the fact that nissan have it 3D mapped but if ur box is already shift kitted then u already have changed the shift characteristics anyway and a very quick and exactly timed ignition cut would probably at low speed make the gear changes feel a lot less jerky.

it's just an idea so dont shot me if u all think it's bl*&^y ridiculous but i had a manual car with a flat shift module that was blowing boxes all the time until it was installed. if ur thinking of the power loss of that half a second with no ignition then just think about the power gain and tunning abbility of having a complete programable ecu on board.

sorry for the long post but i needed to stop thinking about it and ask u guys what u all thought

yeah yeah i know here we go again but i have read so many posts about people trying to find out an ecu that will support some kind of ignition cut, retard during gear changes but nobody as far as i have read nobody has toyed with the idea of the manual flat shift software available in some upmarket ecu's. im expecting to get shot down for bringing this up but i new it was available and just wanted to get u guysto look into the possibility also.

    • Can u check this way it works for power supply?
    • These coils draw 10amps that what i read online
    • I appreciate the detailed explanation, think I understand now. I spent the better part of last night reading what I could about shuffle and potential solutions. I had replaced the OEM twin turbo pipe with an alternate Y pipe that is separated further away from the turbo. The current one is from HKS and I had a previous pipe that was separated even further away, both have shuffle. I had heard that a divider can be welded in to the OEM pipe to remove turbulence, and figure that aftermarket pipes that are more separated would achieve the same thing. From what I read, most people with -10 turbos get shuffle due to their size, though it's a bit less common with -5s on a standard RB26. I think Nismoid mentioned somewhere it's because OEM recirculation piping is common in Australia with -5 cars. It seems that the recommendation tends to vary between a few options, which I've ordered in what I think is most feasible for me:  1. Retune the MAP or boost controller to try to eliminate shuffle 2. Install OEM recirculation piping 3. Something called a 'balance pipe' welded onto the exhaust manifolds. I don't know if kits for this are available, seems like pure fabrication work 4. simply go single turbo My current layout is as follows: Garrett 2860 -5s HKS Racing Suction intake MAF delete pipes HKS racing chamber intake piping hard intercooler piping,  ARC intercooler HKS SSQV BOV and pipe Haltech 2500 elite ECU and boost solenoid/controller HPI dump pipes OEM exhaust manifolds HKS VCAM step 1 and supporting head modifications Built 2.6 bottom end All OEM recirculation piping was removed, relevant areas sealed off I'll keep an eye out for any alternative solutions but can get started with this.  Only other question is, does shuffle harm the turbo (or anything else)? It seems like some people say your turbo shafts will explode because of the opposing forces after a while and others say they just live with it and adjust their pedal foot accordingly. 
    • That worked out PERFECTLY! Thank you big time to JJ. He was able to swap me his stock diff. He drove all the way to me as well. Killer! Removal & install was pretty straightforward. The diff itself is HEAVY. So that’s a 2 man job.  Man does the car drive nice now! Couldn’t have worked out any better 👌
