The PC Pro is working very well. I installed it yesterday and drove for over an hour with no problems . Everything is running smooth and power feels real good. :)
Tom was gracious enough to include the plug-n-play harness and installation took all of 15 minutes. I have it tucked behind the fuse panel access door and making adjustments is very quick and easy. No more reaching up to the ECU, removing the Elf, removing the cover to the Elf, making an adjustment, closing/reattaching the Elf and turning the ignition off and back on again.
Adjusting the PC Pro is super easy and there's no need to shut off the engine in between adjustments. Even making adjustments in the dark is no problem. It is also very nice to be able to adjust fuel in three different rpm zones and see the results on my wideband gauge. I managed to tweak each setting and my A/F is now right around 12.5:1 all the way across the rpms.
I drove for another hour or so today ( both highway and stop/go traffic) and everything is working great.
So far it does EXACTLY what Tom says it will do.
It adds the proper amount of fuel no matter which gear I'm in. The Elf, however, tends to run very rich when accelerating in a higher gear/low rpm situation.
Thanks a lot Tom for your generosity and a very nice product !!!!
P.S. I highly recommend the plug-n-play harness. It was by far the easiest piece of equipment to install so far :)

Since I can't get my shed done and the junk out of the way, I guess I will have to park the Harley in the rain to get room to work on the car so I can try this PC Pro thing. Too hard hearing all the raving and not participate.

It is worth the effort including the Harley cleanup/dryoff.

Harley is dirty anyway, so it will be a good excuse to wash it.

It's all good.....:)
As an experiment today I unplugged the fifth injector and increased the PC-Pro's settings a little to see if the OEM injectors could provide enough fuel for 9.5psi. My A/F is still right around 12.5:1 @ WOT .
I could not do that with the Elf alone. The richest I could get with it was 13:1 @WOT.
Current PC-Pro settings:
Green-Zero
Yellow-5
Red-4&5
Yellow/Blue-8
Red/Blue-8
Since I have an A/A IC, I'm wondering if I should just let the main injectors supply all the fuel (since they obviously can) and leave the fifth injector unplugged until I decide to up the boost some day in the future......:)
The weather's been good and my car is running so well that I'm thinking of scheduling a dyno day just to see where I'm at now.

Warm weather will be back and then you will be happy that you left some of the fuel for the 5th injector to supply and help cool the charge.
I have limited the amount of fuel the settings can add. If you up the boost and run out of settings, let me know. They can be easily changed to allow for even more fuel. The 01-05 with 270cc injectors have a lot of available headroom. My guess would be more than 225WHP before they run out of fuel. However, my oersonal opinion is hat the 01-05 should be limited to 200WHP for longevity. JMHO though. Maybe I would change my mind if I lived where 93/94 was readily available.

I am watching your progress with the PcPro with great interest. I have basically decided I am giving up the elf and based on current results am strongly considering a PcPro this spring.
Now that January is approaching, I am ready to start spending money on my cars again
Tom - I sent you an email with lots of quesitons, hopefully it went through. No hurry on the response, I have lots of time.

It has been a busy week but I did get your email and will reply later tonight when I catch my breath. :)
I do my bst writing at 2:00-3:00 in the morning when the phones are quiet. ;)

That's what I'm scratching my head about......
I'd like to figure out how much (or how little) fuel it takes have the fifth injector working like it should. Right now I have my Split Sec fuel map showing 19.8% @ 7000rpms and 9.5psi.
Do you have a map that provides just enough fuel for a cooling effect?
For some reason I feel more comfortable knowing that the main injectors are supplying the bulk of the fuel but it's hard to know what the best balance is between the main injectors and the fifth.

Here's one you can try. It was for a 110mm pulley.

I used it on my 99 for cooling.

Thanks for the map Tom!
I plugged the fifth injector back in and returned the PC-Pro's settings to where I had them.
I just wanted to see how much more fuel the PC-Pro allows compared to the Elf.
Tom @ Fast Forward

If you really don't need the cooling effect of the 5th injector, the PC-Pro could be programmed to easily run the car at ~200WHP without the 5th injector.
Serpico

That's why I tried unplugging the fifth injector.
The PC-Pro does allow enough fuel at my current boost level (9.5psi) and my A/A IC is "SUPPOSED" to keep the intake temps around 20-30 degrees above ambient temps.
Any idea of how much more the fifth injector can bring the temps down?
Is it possible to read the intake temps from the OBD-II connection with a good code reader?
Tom @ Fast Forward

It can do a pretty good job. This is some old video of the intake manifold temperature under boost. First part is with the 5th injector turned down and the second half is with it turned back on. Gauge on the right is intake temperature. Ambient temps that day were well over 100F.

I am also following this thread with great interest, particulary because my car is similar to Serpico's. Here's my setup:
2003 Special Edition, MP62 w/JRPC & J&S Ultrasafeguard, FM 02 Clamp, 6-Rib w/auto tensioner, (126mm/65mm), SS AIC w/550 cc, STB w/transition kit, TDR A/A IC, PWR Radiator, Westach Boost & A/F gauges, SPEC S2 clutch, Borla "Sport" duals, HDDD, Falken Ziex ZE512, 16" 5Zigen FN01R-C wheels.
I too am interested in the PC-Pro and the 75mm BBK TB. I am also considering dropping back down to the 110mm/65mm ratio with the bigger throttle body. The thing thats scared me off so far is the idle issues some have had with the 01+ cars with A/A IC. Serpico, is would appear that you have things pretty well worked out. I'd be interested in your dyno results if and when you get around to it.

Thanks for posting that video Tom. Where did you measure the temp from?
Blown03,
I can honestly say that I have not noticed a decline in my idle with Tom's BTB kit. It idles much quieter now (no hissing through the air filter), I gained about 1-1.5psi and it reaches redline much much quicker :)
I have my idle set around 1000-1025 and so far no CELs.
The only thing that took some getting used to was the throttle feel in stop and go traffic. There is a little more resistance when first engaging the throttle.
The PC-Pro is working great and I'm very pleased at the way it controls the fuel. It does exactly what Tom says it will do!!!
If all goes as planned, I will be going to the dyno next Saturday!

Since I don't know anything about hotsides, where does the 5th injector reside on a hotside, pre or post blower? I was under the impression they were pre blower and wouldn't have the same cooling effect as the FFS "E Cool" 5th injector. Maybe I misread the initial question of Serpico's post.
Tom @ Fast Forward

I have an intake manifold temp gauge, as seen in the video, and the thermocouple is mounted in the intake manifold in the outlet air stream from the SC. We have also monitored the exterior temperature of the manifold itself with an infrared device and, when set as in the video, the temp of the manifold actually decreases. Not bad when you consider it's mass. :)
In real life, all I set the E-Cool to do is take the edge off the air temp. It is not necessary to cool the air less than what is needed to kill ping. Yes colder air adds more HP but there are better ways of getting that 3-4 WHP than that. For example, an increase of one pulley size is worth ~8WHP. I would rather keep the 4 main injectors doing the bulk of the work.
If you have the IAC valve plumbed correctly, idle improves dramatically. If you can set the idle to 1000/1025, it sounds like you don't have the IAC connected at all?
The 5th injector is in the dummy throttle body. Post blower at the inlet to the IM.
Serpico

I definitely have the IAC connected and according to my tach (which I think reads a little high to begin with) , idle is 1000-1025rpms.
I tried disconnecting the IAC plug and got no change in idle, but immediately got a CEL.
Would swapping the hoses on the IAC valve make a difference?
and yes, I have the fifth injector in the DTB on the intake manifold.

Serpico, are you running the stock fuel pump on your 01? If not what do you have?
Serpico
12-30-2006, 09:34 AM
I've been running a walbro 255 for the past 6 months and have never had a problem with it over powering the fpr. My A/F at idle is always around 14.7.
Tom @ Fast Forward

You could try swapping the hoses but I don't think it matters.
With the 01-05, I don't think you need to upgrade the Fuel Pump below 220WHP. It has 12% larger injectors and they can flow a LOT of fuel. Typically, the problem with boosted 01-05s is trying to reduce the fuel as most of the fuel control cards don't take into consideration the change in injector control and the larger injectors.
