What ecu do you people suggest? I was waiting for the AEM ecu to come out because it had features that the apex'i PFC didn't such as Datalogging and the fact that it is windows based. Well right when the AEM is released I find out that a windows based program with datalogging has just been released for the PFC. Both are about the same price... The PFC has been out for along time but the software isn't developed by Apex'i and I have to buy it separately while The AEM is completely new and includes everything in one package.
What to do? I need to control a street port with intake DP and exhaust. Thanks for any help!

 

Either one.

I would add a wideband o2 kit to your list of additions. Like the one from Techedge, that the Rx7Store should be carrying soon.

You'll need that WB to tune with, esp. since the AEM does not come with a base map that supports your mods.

The PFC does come with a basemap that is pig rich and is a STARTING point for your mods. You can also purchase maps from a few vendors, and from the Rx7Store too.

I prefer the PFC+Datalogit+DIY WB o2 combo. But I'll be testing an AEM and tuning with it, as well.

 

I would rather go with the AEM if you are going to do it yourself. The datalogit software doesn't do everything that an authorized power excel dealer software would do. Also the support for the power FC really sucks especially if you aren't in California

 

What is Power Excel and what more can it do compared to datalogit?

 

Either way, it's good to tune it yourself or with an experienced rotary tuner.

PFC has a lot of people using it and perhaps you can get support from the guys on this forum.

AEM is relatively new and you won't get much support from this forum since we are tuning it right now.

the power excel software is apex'i official software used to tune the power FC. Only authorized apex'i excel dealers have access to this software and can actually dyno tune the power fc with it. There are only a couple of authorized excel dealers: XS engineering, sr motorsports, carboy, rotary performance, and motorsport dynamics who actually have the software. The power excel software allows access to all options available in the power fc, the datalogit allows a lot of access but not as much as the power fc (but then again, it's only on its first version later versions may be even better).

The datalogit is good in that it allows do-it yourselfers to tune yoru car by yourself. The excel software is only available if you go to an authorized dealer to tune your car.

 

Wow... Never knew that! Do you know of any specific things excel has over datalogit? I have heard from a few shops that XS Engineering is the place to go when buying a Power FC because they can tune it better than the other places...But thats just what I've been told. I have looked for more information on the datalogit (besides Rx7store) to try to compare the features of the AEM but can't find anything. Has anybody already done a side by side comparison... I'm not talking about physically testing both, just comparing features/stats?

 

Hey i went to XS engineering site and noticed it was only 30 min away from where i am. If i was to take my FD to them, would they dyno it for me and help me tune the PFC. Also is SR Motorsorts located in Pleasonton, CA cause i see their area code is 925 but they have no directions to their store. And would it be the same with them, can i take my car in and they would help me tune it with the PFC or would i have the buy the PFC from them in order to get the support.

 

TKdan, XS is in huntingdon beach in LA, that's quite a bit more than 30 minutes from you. I believe that Shane Racing is in brentwood. I called ray over the summer and he said that he does dyno tune power fc's, but to this day, I have not met anyone who has actually had their car tuned from him other than with super rich maps. Ray will Map your power fc, which is total BS considering that every car is different. I would rather drive 6 hours to LA than send my power fc to ray

 

I have seen maps from both places. I would have to say that Ray's maps are what I would buy if I could not tune/ do them.

 

Yea, i did the search for a dealer and it brings up other shops in my area, and not just XS. Anyways, the shop that is 30 min away is SR Motorsports. Have you heard of them dyno'ing the car and helping you tune the PFC? If so how much does that cost to do? I don't have my PFC yet so everything sounds confusing, maybe once i get it it will be easier since i will have a manual to read.

 

Oh, i thought Ray was at XS. Now that i know he is from SR Motorsports i have second thoughts about going there. So all he will do is install a pre-made map that isn't even configured for my mods? Or will he acually dyno it and help me tune it for exactly what my car needs. And if SR is of no help, is there anyone in the bay area or in Fremont, CA especially who could help me? I think since i don't own the PFC yet i am confused, i just might need someone to show me then i will get the hang of it.

 

Tk5dan, contact forum member osdesigns, he can do it with the datalogit. He is in the bay area.

as far as maps go, they are bullshit. How can a so called "tuner" know the exact parameters of your car without even seeing it? Every car is different and needs to be tuned accordingly. I called Ray and he says that he has a dyno in his shop and that he does indeed tune power fc's on the dyno. Although it is quite interesting to note that no forum member has come forth and had anything to say about anything he has done other than do maps which are super rich. I know of someone who had an SR map on his single turbo FD and with it, his Air fuel is 9 to 1!!!

 

I'd also like to hear specifics on what the Power Excel software can do over datalogit. All that's been said so far is that you can dyno-tune with it - but I don't know what that means. At KDR we dyno tuned just fine with the Datalogit.

Without specifics I can't imagine what is left out of the datalogit. There are things you can change that are very esoteric and that you'd never want to change.

I've found the support for the PFC and Datalogit from this comunity and the Datalogit support mail group to be quite good. And the datalogit software keeps on getting better. It's a really good tool for tuning. New features include analysis tools to map logged data into the trace cells (so you get a 20x20 grid of whatever values you want, O2, wideband input, max duty cycle, average wastegate, etc....

Anyway, all this is in defense of the Datalogit vs Power Excel. I have never used the AEM, so maybe it's even better!

But (grin) does it support a boost level control swith? Does it? I can now flick between 10lb and 13 lb boost settings from a switch on my console - pretty cool.

 

Hmm. Rotary Performance isn't very far from me. I suppose I could just have them do the power excel tuning for me and I could just get the brain w/o the commander or dataloger - right?

 

so,is it possible to tune the powerfc without the commander?just with the datalogit?

 

Ya,
