Anybody have an EJ20G PowerFC/Datalogit map?

[RallyColtTurbo]

Due to an unforseen headgasket failure in my O.G. Legacy turbo it was neccisary to install my "spare" EJ20G before my built motor was ready. It's an early Legacy EJ20G w/an early WRX TD04 and topmount intercooler. If anybody recalls (or cares ) I've been running my EJ22T on an APexi Power FC for almost a year now with zero problems. It didn't like my EJ22T map at all, so I did the reset. It learned the idle just fine and drives really good at light throttle.

Well, what people say about APexi's preprogrammed "base" map being to aggresive is apparently true. Definitaly not safe for SoCals 91 octane pee water. I've already pulled 3-8 degree of timing in the higher loads and the higher RPMs and added a bottle of octane booster...I still get knocking. What I'm loking for is somebody who might have a fairly conservative map I can use as starting base. Unfortunately this is my daily driver so I need to drive it or I would just keep playing with the map.

I'm not looking to "steal" any tuners work, just something to get me started.

Any help is really appreciated. PM if neccisary.

my experience was not just high advance but way lean afrs (like 14.7 across the board)

In the meantime you can throw the Ej22T ECU back on there. I ran my EJ20G swap on the Ej22T ECU and it ran perfectly. Just something to keep your engine safe and daily-driveable until you can sort the maps out.

Got the map toned down OK now. Now I have to decide if I want to get this motor tuned, or just wait until the "real" motor is finshed.

At risk of embarrassing myself, but I'm goning to post this for those that actually search. I've done a ton of reading and somehow missed this little tidbit.

When installing an EJ20G Power FC (prolly EJ20K also) you must set the boost control kit to "on" if you want the PFC to control the boost. Even with no kit installed. Even if using the stock MAP and boost control soleniod, you will not get any boost control unless the setting is "on". Apparently the logic/code is disabled altogether if set to "off".

If your using another solution for boost control, either setting will read boost just fine.

That is all.....on to your regularly scheduled program.

^ Although I remember reading that when I was going to use the PowerFC, I wouldn't be embarrassed by missing something like that. I believe the only reason I caught it was because I was going to run the PowerFC BC and needed to know how to set it up. I've read my Link ECU manual probably half a dozen times and will still miss something.

Usually the boost control kit is set in the default on position on a Power FC unless you have a used unit which already has been programmed and haven't reset it (which you should do).

Anyone using a Power FC should read this whole site http://paulr33.skylinesaustralia.com...owerfc-faq.htm

Yes, it has been reset many times, and every time I turned the setting off. I've read the FAQ a few times, but as stated, I missed or forgot it.

[rockcrete]

The FAQ is for Skylines, and they won't start if the boost control is on and you don't have the boost control kit

At least GT-R's won't anyway - not so sure about other Skylines.

Anyway, my comments were more general information for anyone else reading this that may be having trouble than directed at you......

Like many other ant species, these ants form trails with their pheromones that remain stable for hours or even days, making the trails analogous to vehicular highways.
“Our study clearly demonstrates that ant traffic is very different from vehicular traffic, in spite of superficial similarities,” Andreas Schadschneider, of the University of K?ln and the University of Bonn in Germany, told PhysOrg.com. “It also raises a fundamental question: how do the ants achieve practically ‘free-flow’ up to such high densities; our experiment demonstrates what happens and we also make a theoretical model of what might be responsible for this behavior.”
wow gold
To observe the ants in their natural setting, the researchers set up video cameras at sections of 10 different one-way trails that had no intersections or routes that branched off. Surprisingly, the scientists never observed individual ants speeding up to overtake another ant in front; the ants followed each other in single file. This behavior, of course, contrasts with vehicular highway traffic, as well as most other known traffic forms.
Most significantly, the scientists found that, unlike vehicular traffic, the average velocity of ant traffic remains the same in spite of increasing density. Consequently, the greater the density, the greater the flux, so that more ants travel down the trail segment in a given amount of time. In contrast, vehicles on a highway tend to slow down when the traffic density increases, eventually resulting in a traffic jam. Along the same lines, the researchers noted that most types of high-density traffic exhibit mutual blocking, in which a vehicle is prevented from moving by neighboring vehicles and also contributes to the blocking of those vehicles. However, the researchers did not observe mutual blocking in the ant trails. wow gold
As the researchers suggested, perhaps evolution has optimized ant traffic flow, since ants are known to have highly developed social behaviors. In their study, the scientists observed that ants tend to form platoons in which they move at almost identical velocities, allowing them to travel “bumper-to-bumper” while maintaining their velocity. At higher densities, platoons merge to form longer platoons. But because their head-distance remains the same, traffic still maintains its same velocity even as density increases. This behavior is very different from highway traffic, in which vehicles close together tend to slow down.

Stop posting crap in peoples threads!

I've just been messing around with my Power FC on my GF8 and can confirm that the stock map is too lean up top.

I was getting knock and couldn't really fix it with timing, but as soon as I upped the fueling it fixed it (and maxed my stock injectors out too).
