This is fourth gear pull on a Mustang dyno. The car has an Turbo back RMR 3" with Random high flow cat, K&N stock filter, Unorthodox under drive crank pulley, and running 21-19PSI. We logged wide band O2 through the FC, this is with high to mid 10's A/F ratio.
I can see why people are running this rich, anything leaner than this and you start to pickup some mild knock. We will be doing some addition tunning/logging on a road course, street, and more dyno pulls on a AWD Dyno Jet. BTW this Mustang dyno has shown to read almost identical to an AWD Dyno Jet.

 

Nice numbers man, and thanks for the info.
Where and when can I get a Power FC?

 

Can you share your settings?

 

I will hopefully be purchasing a D-Jetro Power FC tomorrow...

Couple of Questions:
1) Are you using the power fc to control boost?
2) Can you share your settings?
3) Have you purchased datalogit yet? If so where and how much?

 

Hey SILVER give me a ride!!! I live in Dallas. Check your PM's

 

The supplier/tunner I am working with has these units in stock, I am sure some of the other APEXI Power FC dealers will be getting them in soon as well. I have basically volunteered my car as a test mule, this is my daily driver and I have an FJO wide band O2, EGT, oil temp, and of course boost gauge, (all with record/playback and peak hold) permenantly installed so this helps a lot for test and tune. The supplier I am working with does not want to offer these systems for sale until he has had enough time to develop and test several maps. They do not want to be harased until they feel it is ready to sell, if you read my clutch fix post, this may end up being a similiar deal.
We have already found that both coolant fans do not come on high speed until 100C (212F), (or if you hit the AC), and the function to adjust this is blocked out on the APEXI tuner interface. It is not a big problem but he is not going to sell these until this issue is resolved.
In the mean time we are developing maps for various configurations, and testing under extreme situations.
We have only tested the standard (non-D-Jetro version) so far, it comes already loaded with a highly developed map that allows the car to idle and drive better than a stock car! It is also tunned ultra conservative from the factory, so you can plug it in and go with out any worries or drivability issues. To make better power you need to then lean it out and advance the timming in certain areas.
Other than the minor issue with the coolant fan control the system has been running flawlessly.
The Datalogit tunning option is supposedly ready but it has not come in yet, so far I have been working with an APEXI certified tunner who has the APEXI tunner interface. I have been driving the car daily monitoring what I can with my gauges and a commander, and every evening we are logging and making adjustments with the tunner interface, so far mainly driving on the street and on the dyno. Right now I have no way to share maps, but once the Datalogit is available I will have no problem sharing maps. Like some of the other systems available there will be web sites with down loadable maps.
So right now they are in stock in the US, but at the momment at least the shop I am working with is not selling them, accept to a few customers like myself who are willing and able to act as test mules. Some of the other dealers may be selling them right now, but I do not know of any, accept maybe MZM.
I am not currently using the Power FC for boost control, but I am told that it will control the stock selonoid with out the need for any additional boost controller kit, I will try using it this weekend.
Maps for the D-Jetro version will obviously not be the same as the standard version so....
BTW, the shop I am dealing with will be selling the standard Power FC for $895, the D-Jetro version is $980 including the required Map sensor. The optional commander retails for $350, you don't need the commander but I have seen people mount them in the car with like a cell phone holder and use them as a gauge. It can monitor 1, 2, 4, or 8 different parameters real time and has a very limited log function. Some of the parameters you can monitor are: Knock, water temp, air temp, ign timing, injector duty cycle, battery voltage, speed, engine RPM, and MAF values. So $350 would be pretty good for a gauge with all that functionality, plus it can adjust engine parameters!
For people like myself that want to do there own tunning, the Datalogit will be the way to go. I am told it has nearly all the same functionality as the APEXI tunning interface (only offered to certified dealers), only not quite as slick. I am told the Datalogit will be slightly over $300 (dont have firm pricing yet).

Any one in the D/FW area interested in doing some testing PM me.

 

Well, curiosity got the better of me so I hooked up the stock boost control solenoid. The answer to "does the Power FC control boost without the added boost solenoid kit" is yes and no. It does control the stock solenoid and gives you essentially stock boost, I had the restrictor pill removed before I went with a separate boost control, so now I saw 20-21PSI tapering to 17-18 PSI, pretty much just like the stock computer. The problem is that APEXI does not allow you access to the duty cycle control for the stock boost solenoid . For certain other cars the Power FC does allow you to adjust the boost and there is no good reason why it could not be done here. They obviously have the ability to do so without the need for an additional control solenoid, they just need to release that control function in the software.
My distributor/tuner is going to see if APEXI can release that function along with the fan control, which absolutely needs to happen.

 

Yea, Kick butt #'s.


Man, APEXI needs to come off with the software.

I would like to say Thank You Silver Surfer for testing and turning the new APEXI.

 

Damn look at that flat *** torque line, holy bajeezus!

 

I know, let me tell you it feels as awesome as it looks. This dyno is accurate but the resolution on the print out dyno graphs kind of sucks. It can show more detailed graphs but the operator said that he did not know how to print those out.

I am anxious to get some dyno Jet graphs were I can see and show much better detail, (should be later this week).
Our goal is to make max HP/TQ while keeping the knock sensor values below 6-7 at all times. It's easy and already there at WOT, but the transitional areas is what takes more time. Hitting all of the various load points under actual driving conditions we keep finding little holes here and there where you can get some intermittent knock. There are also just certain load/RPM points where the engine seems to be more sensitive to knock so you need to fatten those spots up and or reduce timing, 3-D mapping really helps.

I could not imagine trying to tune this thing without the kick *** data logging/adjustment function of the tuner interface, I am also anxious to try out the Datalogit.

After we get this thing making as much HP/TQ as possible and 100% knock free under all conditions, the map will be tested in a few cars. Then they are going to add 1% fuel/-1 degree timing across the board and that will be the base map. Right now I have full 3" exhaust with high flow cat, (planning to run test pipe also), I am also planning to get colder plugs, cams and adjustable cam gears. We should have some good maps for these mods and of course stock.
I am having a lot of fun playing with all this stuff, I cannot wait for others to experience this system. I knew it was going to be good but it has truly exceeded my expectations.

 

any more news on the power fc?

 

Still haven't gotten a fix for the fan control issue yet. The datalogic should be in next week. I was running into some intermitent knock running high boost (21-22PSI), that turned out to be the stock fuel pump running out of steam.
While I really need/want the power and flexability of the Datalogic, I am also starting to gain a lot of respect for the functionality and convienence of the commander.

I think this system is a great option for those who want more than what the piggy back or reflash options have to offer, but are also not ready or willing to go with the level of tunning required by something like the AEM.
If your looking to go to speed density to make 400, 500, or more WHP, and don't mind constantly driving around with a laptop in the passenger seat, the AEM might be a better choice.
If your looking to get 300-400 WHP and also want the ability to monitor and make adjustments on your own, an L-jetro Power FC with a commander is a great option.
IMO the commander is one of the factors that really sets this system apart from the other options out there. While it is an extra $350 (over the $895) it also doubles as a gauge package. How much would you have to pay for a gauge package that can monitor 8 different engine parameters with peak hold and 15 second record features?
It also has an outstanding reputation as a trouble free plug and play engine management system.

With that said I also think the AEM is a kick *** system, especially for some one like me who loves to tinker. For my performance goals I don't think it will really give me any more than the Power FC, but the tunning flexability/power intrigues me. If you haven't already done so, down load the software from AEM, it is very nice. I will be very interested to see how they preform in customer cars.

 

holy **** i was my torque was as flat as that~!@!@!@!

I just dynoed at 310whp, but my **** isnt anywhere near that flat. It was on a Mustang dyno also... I should up my chart. Could you please tell me what your maf settings look like? Assuming the Power FC doesnt run map....
