Advice on PW Dyno sheet inside

This is a bit off topic here but I will receive my pw next week and I was just wondering if the pw calibration will work good with a race header...do you have to tell them you have a race header when you send your ecu to them?

stock exhaust is to give you 220whp and 180ftlbs, the HKS is 2.25, if you go to the focussport.com and look at the dyno that they did with a PW kit it shows 221whp with 181ftbls and the exhaust on that car is 2.25 in diameter, yes 2.5 is alot better for FI but having a 2.25 exhaust wont kill your numbers by a whole lot. Laz(focusfuri75) got very nice numbers with the SVT headers and borla exhaust which is 2.5 so having different headers doesnt hurt it , you benifit from it. can anyone address the issue of a corrected dyno run and an uncorrected run? car showed 6whp more and 6ftlbs on the corrected run.

The standard HKS zx3 under axle system is 55mm ( 2.165 in. o.d.) I have one sitting in my garage. The HKS SVT system is 60mm ( 2.36 in. o.d.) not 2.5 as I quoted in my last post. Which one are you running? Reason I ask is I have been curious how the under axle system performed with the PWSC.

OK so you're running the stock PW Tune with a race header right? That'll throw it into open loop cuz the second O2 sensor would be getting bad readings on the race header. Are you running an O2 sensor cheater?

I'd bet that might be some of the problem.

yes i do have an O2 cheater, so taking it off might help? or should it be helping? and the piping, your correct OGFocus99 it is 55mm which should be 2 1/8th slightly under 2.25.

I guess you need the hint too...the O2 or cheaters would make no difference at all @WOT :D

Maybe. maybe not. The adaptive function might be screwing it up just a smidge.

Maybe disconnect the battery and reconnect right before running to see if that isn't the issue. (in theory it shouldn't mess it up I know... once throttle position hits a certain point, open loop and there you go.... but something in obviously wrong).

As for the knock sensor. It could be picking up something other than acutal detonation. Run a full tank of 100 octane and if the knock sensor is going haywire you'll know for sure.

Pssst. Hey, you don't know as much about the Focus ECU as you think you do. ;)

PW leaves adaptive learning on and WOT can indeed be affected by the trims that were learned. Not saying that is the case here, but you are acting like it can't happen, but I've already seen it happen first hand.

RIIIIGGGHHHTTTTT....sooo...it trimmed itself to 10:1 at WOT...LOL...with no MIL...with a stock O2. Ummm...no. Poke a needle-sized hole in a PCV connector and you get a MIL for lean limits, but this baby is pukin' fuel at WOT and it's just a trim issue.


I have a hunch that I know just as much about them as you do. Plus some other stuff. :D

Ooops...forgot where I am. I better say right here that you're the BEST FOCUS TUNER IN THE WORLD!!!!! What good is buying all that influence if you don't get all the capitulation you're paying for? :)

I'm out...hit up FF in the FI/nitrous forum. Mom's here. Can't talk on the phone anymore. :lol: Besides, it's no fun discussing stuff when only one of us has the "delete" key.

Wow, you really hate it when anyone questions you don't you? Are you ever wrong about anything?

I clearly stated that WOT CAN be affected by trims since you seem to think differently. Problably wouldn't cause it to go into the 10s but that would depend on what was being commanded in the base fuel table - and we both know that you don't know what PW is commanding. You might want to read my post again. ;)

Also, I'm curious...just how many Focus ECUs have you tuned?

And you know I still have all of those replies to your "11.5:1 A/F ratio is too rich" viewpoint. Would you like to see them? :)

Oh and Joe, lets face it everyone knows that YOU are the best Focus tuner in the world.

(Hint for Todd and the PW guy: They're ALWAYS open loop under load.)

Sorry, that is also incorrect.

The US and Canadian spec Focus ECU goes Open Loop based on TP not Load. I remember a while back WeldingRod was at 150% load and still in closed loop. Going up hills IIRC.

It's not a questioning thing...it's just that when I tell you on this board that you're full of crap, I'll get banned because you buy advertising on this board. I've already been told not to do it here...trust me.

If you want to discuss who's full of crap and who's not, come on over to an open board and we can throw down. Doing it on here is a joke, because you're the only one allowed to speak his mind.

You can try all you want to split hairs and blow smoke...you and I both know that that's all it is.

A cheater or bad O2 isn't going to make a car go 10:1 at WOT and you know it. Ain't no trim going to make a car go that rich and for that matter, you know we're talking about WOT, so don't go throwing around a bunch of nonsense about how the ECU defines it.

And yeah...11:5 is too rich. But again, I'm more concerned with power, reliability and efficiency...not blowing smoke.

Wow...so they run cars on the dyno at part-throttle??????

Damn...

In case it wasn't clear enough from all the previous posts...we're talking about FULL-THROTTLE. I'm not trying to impress all the noobs with my tuning prowess, so I'm not getting into all the various PIDs and how one effects the other to make myself out to be some tuning wizard.

He has a problem and I'm trying to help out, not conduct a training class on tuning parameters. Get over yourself already.
