Tommarow morning I am going to the track... I was thinking about upping the boost past by current 7.5psi but I decided its not a good idea with stock timing even on my 100 octane gas.

I took a look at my E-Manage timing harness... but then I took a look at my FCON...

I took the FCON off the shelf, did some quick wiring... installed it in the car... built a little base map... and fired it up.

It runs, and it runs perfect. It is idling clean, and reving fine, and fine for part throttle driving.

Now I have to decide... I am leaving for the track in 10 hours. Do I leave it be on the E-Manage for now and get some sleep and run tommarow as the car was... or do I spend all night getting the car tuned on the FCON so I can run a little more boost tommarow and crack well into the 11's???"??

Really tough call... considering I am extremely paranoid ALREADY about just throwing a rod from the HP... I am not sure I want to add in the fear of breaking a piston while trying to get it tuned.

HMMMM

 

Very amazed you were able to insert FCon V - With Timing harness and even get it to run.. Maybe the design of the two unit's have a common designer..

I'm sure GQ_626 and others will give recomendations..

But - seems with your recent "Good" runs to be cautious.. and stay with the work you have done on the E-Manage.

I watched the film "the passing" and heard your friend say
"he can't get a good hook up - go back and warm the tires up"

Got some FRS radio's ?

Cheers Amy -

And best of luck tomorrow..

 

Are you using an EO1?

GQ-626 is current..
350Now - Knows EO1 - but working on "how to"
We mortal's are waiting for input from you "pioneers"

Cheers Amy -

P.S. Update your Sig - ( actually add to it.. about the 12.X ET )

 

Which way did you run the FCON? Piggy back or replacement.

Just curious as the PRO can do both.

 

The FCON V Pro is a standalone EMS and does not operate as a piggy back. The stock ECU is still in the car but its funtions do not include running the engine anymore... the FCON does all that.

Some people call it piggy back since the stock ECU is in there... but in all reality there is nothing piggyback about it. The stock ECU is not firing any coils or injectors... it just thinks it is... and the FCON is not alter any signals to make the ECU do something it doesnt normally do.

Stock ECU stays in for emissions testing, fly by wire, gauges, etc.

 

phunk..

As you say people have different thoughts about the term "piggy back". Where I live we consider if the original ems/ecu remains in the car then the FCON is considered a p.back. I do see your point though about it is really not controlling much.

The reason I asked is that I wanted to see if you managed to remove the oem ems and got the FCON to control the fbw and to see if the CAN system still works without it.

I had a rude shock when I checked how much the FCON harness for the 350z was. Nearly 1/2 the price of the FCON itself.

Best of luck with the FCON. It is one excellent unit.

 

Phunk, I wouldnt rush it with a 10 hour caffeinated test and tune with a new FCON. Have fun at the track with the eManage, and then I'd recommend taking several days of tuning and programming to get the FCON right. Just my .02...but I'll be following your progress with the FCON VERY closely.

Oh...by track...do you mean 1/4 track? Or a track day?

 

phunk, dude.... youre getting closer to my goal. My car is gonna be yours to tear down and creat a monster very soon, thats after you do your motor I have to call you and talk.

 

Let me know Rayden. The car is like absolutely perfect as the performance machine it sits as now. The only problems are that:

A) Its on the edge, and more precision tuning via the FCON would be a nice margin and so would forged internals

B) I want faster timeslips and more HP. The car is perfectly balanced as it is now between the brakes, suspension, and power level. But I need to add another 250rwhp or so before I will be content with it.

I will, very very soon. I want at least 600 rwhp. I have almost everything for a new motor now I just want the shop thats gonna do my work, has all ready built one up before mine. I don't wanna take any risks when I drop that much money and blow a motor because of a mishap that was overlooked. But you know what I'm talking about, I've seen that mr2 and your hatchback, crazy power...and thats what I want.

 

How is it that you're getting much more HP than others at the same boost level ? I suppose it means you're running it with much less margin for error, and much more lean ?

In terms of engine stress, its probably like putting your engine through 8.5psi with another engine management solution ? In other words, no matter what the boost is, you're putting it through more stress than people running 8psi and getting 400whp, correct ?

 

slay2k: it depends on what components your concerned about.

The reason I am making more power than others at the same boost... well there could be a few.

First everything is setup very well. There are no exhaust leaks anywhere, everything is ceramic coated and heat wrapped. The tuning is clean... and most of all I am running 100 octane at all times.

At the HP i am at I would assume that my engine is under less stress just because there are not even any HINTS of any type of ping or detonation thanks to this fuel. I am still running stock ignition timing, which has a lot to do with it combined with the 100 octane.

100 octane is available all over the place around me and I have no issues filling up with it every time I fill the tank.

The only thing in my engine that I have any concern about stress is the rods, and just because of the HP level.

Also, no I am not running the car lean at all. It is always in the high 10's to low 11' A/F. Depending on conditions it will sometimes go up to the mid 12's, but when I was on the dyno it was always richer since I was tuning it there.

 

As for the FCON... i removed it that night so I could go to the track in the morning without any worries.

I will try and find time this week to get the car all tuned out on it.

I need this all ready for the new motor, which is getting closer and closer. Hoping for completion in 3 weeks.

Charles,
As far as the FCON programming goes, I think alot of us are interested in the removal of the factory MAF sensor, replacing it with a MAP sensor. I know the FCON will support this, and for all those looking to build their motor, this will most likely be a necessary step. Your thoughts?

 

Can you explain a bit more on what "quick wiring" you had to do?

 

T32gzz: My car was running without the MAF when I had the FCON in there temporarily. The FCON can also run the MAF, but I dont think many people really run standalones on a MAF.

I dunno... my thoughts on it... MAF is a better way to run the car if you can do it right... but it starts to get hard at very high HP levels if you dont have a massive sensor or the ability to run the sensor on only half the engine, or the space to even put the sensor before the turbo...

IceY2K1Max: I had to setup the FCON harness to accept a TPS signal. The FCON harness was not originaly intended for the VPRO, it was designed for one of the piggyback FCONs. However the ECUs main plugs are the same and the TPS wiring was the only thing that had to be setup to use this harness with the VPRO, and this wiring change was made within the FCON harness... installing this never involved have to cut or splice a single wire in the car.

 

want me to make a short video maybe so you guys can see the FCON in action? I dont have it tuned, but I can show you how simple it is to install and what the software looks like and prove the car runs on it...

 

So, once you mod the FCON piggy harness for a TPS connection, it's pretty much "Plug-N-Play" using the VPRO, ie no splicing/tapping OEM harness?

 

Precisely. Also, The FCON system has its own independent harness for the MAP and AIT sensors.

Never had to tap or splice or even look at any of the OEM wires for install... its plug and play.

See if you look at this pic of my stuff, you can see the harness. It has plugs to plug into the stock ECU, plugs to plug into the cars wiring harness.... and then its got everything spliced/routed/tapped, etc, all within its own harness.

This also makes it easier to install anything else into the car cause you never have to splice the factory wiring, you can do it to the FCON harness and save your car from a wiring cluster****.
