GReddy E-Manage Decision
I've decided that a piggyback ECU should be my next upgrade. The choice as I see it is between GReddy and Canzoomer (which also contains the E-Manage). In order to decide I have some specific questions that I haven't found answers to:
1) How has the E-Manage install changed since MazdaManiac's install before the Canzoomer days? (i.e. Is splicing into the wiring harness still a necessity even with the newer GReddy pieces.)
2) With E-Mange is frying the ignition coils still a concern, and if so are they ways to fix it DIY with parts, soldering gun, and patience?
3) If I were to take this link: http://www.greddy.com/prod_e_manage.htm to a shop what items exactly would I need to tell them to order?
I plan on spending my own time tuning this so Canzoomer's preloaded map doesn't give that much incentive beyond a starting point. Also, I still plan on buying Maurice's CanScan so I can pull data off the CAN/OBDII connection.

Ok. So this isn't exactly picking up pointers quick. Here's what my guess would be parts-wise for a new E-Manage install (http://www.greddy.com/prod_e_manage.htm):
E-MANAGE (basic unit) piggy-back engine management unit
E-MANAGE INJECTOR HARNESS for main and sub. inj. control
E-MANAGE IGNITION HARNESS for ignition timing control
RPM SIGNAL ADAPTOR 3 RX8 ADPT.
E-MANAGE SUPPORT TOOL CD w/ spl. serial to USB cable
Am I missing anything from GReddy? And should I still get out the wire cutters and soldering gun?

Ex- member.
1) There's a RX8 piggyback harness available here (bottom of page). You do all the splicing to that and not your factory wires. Pricey, but better than soldering or splicing your stock wires.
2) I've had the Greddy turbo for a couple of months now and have had no problems with the emanage frying the coils.
Most people here have the emanage as the engine management for the greddy turbo. I know MazdaManiac did use it to tune his stock engine, but even he's custom turbo'd now.
3) Your previous list looks good.
One more note, there's been reports of a new emanage (gold or silver) coming out this summer. What the differences/ upgrades are to the current blue emanage, I do not know.

That link is pretty handy. Although the $198.00 price tag for the harness is kind of steep compared to the $80 for GReddy's two harnesses. I don't know if GReddy's could be spliced into something comparable.

He has good parts and availability. More importantly, he is a good guy, an active supporter of the E-Manage community and will take care of you with regards to service and support.

This "patch" harness is a nice thing, but I agree that $200 is a bit steep just to save yourself an hour or two of work.

With MM's latest info there seems to be a distinct line drawn between two areas. The line drawn is the matter of ignition timing control and h.p. adders with/without it. I guess with my nitrous project and with MM's turbo kit we have pretty much proven that the RX-8 can tolerate about 55-60 additional h.p. before timing becomes an issue.
As more and more people delve into h.p. add-ons greater than 55-60 we will gain more insight into what all is needed to accomodate these higher levels of boost. It will be nice when we in the RX-8 community have a template from which we can pre-plan our base maps with some degree of accuracy so we know what kind of ignition curve works best with certain levels of manifold boost or nitrous boost.
All this almost makes me want to apologize for having to put the power-adder portion of my mods on hold and, instead, get to structural/drivetrain mods.
MM, you help make more power and I'll show everyone how to contain it.

If you use the E-manage or CZ to drop the A/F values by adjusting the MAF output...the PCM responds by adjusting the timing a bit. This results in needing to add about 4 deg of advance above 7000 rpm just to stay at the max stock advance of 30 deg at WOT. This would be an advantage to you NOs guys, as a bit of advance spraying would be a good thing. The only problem is you don't really want the leaning either..........If you lean it out...and then add back a bit more spraying it might work well.

What is meant by "advance spraying"? The only reason I want to use the E-Man is to reduce the ignition advance enough to prevent detonation with the particular h.p. boost I would like to use. If I am somehow able to also tweak the factory maps for better overall performance then that would be a bonus. From what I am able to deduce so far, once I go WOT the open-loop mode is activated and the E-Man can consistently alter the map successfully. If that is not the case, then I will wait a little further until someone figures out what to do. Until then, I'll move on to the mechanical stuff.

Thread hijack!
Is it possible to connect the e-manage to the usb-port on my laptop? cause I seem to have misplaced the cable that came with it....
And also,,, Last time I started the e-manage support tool I got a question about upgrading. Is this safe or would it damage or ruin something in the e-manage?

I don´t want to spend more money...
Sorry to ask, but has anyone tried hooking up the e-manage usb->usb?
