I'm abou to install a PowerFC in my ITR.
Trouble is, the manual is in Japanese.
Anyone know where I can find an English version ?

Cheers.

 

Power FC is a plug and play unit. If it doesn't fit, then you will need to get a wiring harness to suit your application... or make your own.

 

It's not the fitting that's the problem.
It's just a plug in job.

It's the settings that are the problem .

 

Settings? The PowerFC is application specific... the common versions are for the B16B or B18C. The car should start with no problems once you plug in the PowerFC.

 

not true dude...these things come with very poor base maps... It won't even idle if you try to plug it in and start it...you will need to 'teach' the ecu to idle...and I wouldn't drive it as-is... Usually people here buy it from dealers who carry there own base maps, or who can custom program them...


BTW

this is the PDF (adobe acrobat) version of the instruction manual in english....its for the RX-7 but its enough to understand whats going on

Make sure you have a B18C base program. The manual won't tell you how to set it but it will tell you what some of the setting do and what the abbreviations mean.

Here is a power FC link for the commander from some RX7 users. ALthough it is listed for the RX7 the controls are the same. It explains everything QUITE well.

Beat me to it. But I must disagree. Mine idled great as soon as I plugged it in. no teaching at all.

 

Cheers guys

That's what I needed.

It's sitting idling at the moment to learn the idle.
Then I'll go and see what base settings need to be done.

 

Yours must have had a different base map...mine had one from the factory and no idle speed set, so I had to teach it...none the less, you will need to program it to fit your needs

 

Well, I don't suggest driving the car with maps that are not suited for your car. Hence, the PowerFC is used for "tuning" and you don't run your car with base maps. However, the car should start with no problems with maybe a little rough idling.

I have been tuning these babies for so many times now... so far, I have never heard the problems you have mentioned.

 

Here's what I had to do:
First time I started my car with the Fc in...it just kept stalling...no idle...If I held the throttle down it would run fine...but as soon as I released it, it stalled...at first I thought 'WTF'

So I e-mailed the dealer, and they told me that mine had factory programming and that I had to "teach" it to idle, or that I could take it back to them to get one of their base maps...well my car is turbo, so none of their NA maps would work, so I read through the instruction book (in Japanese)...took me hours!

It said that I had to hold down the throttle for ten minutes and idle it between 800-1000rpms...this isn't as easy as it sounds 'cause my foot kept falling asleep.

After 10 minutes, I had to turn on the air con and lights, to make sure that the idle came up...then I had to wait 'til the engine fan kicked in....after all that, and it didn't stall, then the its ready to idle on its own.


If you didn'd have to go through all that, then I'd say your dealer pre-set yours for you...

 

Do the PowerFC's come with different base maps, or is each ECU specific. When I got mine, it was a B16B base map... was there a way I could change it to B18C base map, or did I get the wrong version ECU?

 

Power Excel dealers would have to change it. Basically the wrong one. IF you have tuned it up i would think you should be ok.

 

Gotcha... so, it comes with both maps, but defaults to the B16B. Ain't that a bitch. No PXL dealers near me... I'm SoL.

 

OK it's in and running .
The base map is OK.
The only thing now is the check engine light coming on .
It flickers on at approx 5k rpm and then at the limiter .
Only under WOT load though.

Any thoughts.

Cheers.

 

Knock?

 

5K might mean that you have a knock level above 60, and the limiter light is telling you that you're beyond X% of your injectors.

The Check Engine Light is used for:

Knock
Injector Warning(beyond X%)


This is explained in the RX-7 manual, which I assume you've already read?

Austin - who once owned a PowerFC

 

Sorry.
Yes , knock .

It happens at the same time as the highest knock figures .

 

Then use the "Map Trace" tool and find where the knock is and either add in additional fuel, or remove some timing in that area, or both.

Austin

 

Not read it properly yet .
Will be doing asap .
Does it explain these things ?
Just wanted to know if anyone had experienced this on the ITR and knew what it was.

 

cheers Austin.
Looks like I'll be reading the manual tonight

 

Your in the same boat as me. Powerful tool and not a lot of experience. Just be careful and save the major tuning for the dyno.

I tinkered with mine based on O2 readings and knock at WOT and I actually feel like the base map was where it was strongest. Need to get on a dyno with Wideband to be sure.

 

one flash means injector at 100%
3 fash means detonation
i have that for the injector, ohh well i don't have a commander, no commander works on mine i have to get the newer version commander..my is the latest version
