GhostTribute It's not always just about HP.....There is a reason that most every professional road race team uses COP and fully sequential fuel and ignition... power isn't the only reason for this. I am not new to forums so I completely understand why HP always seems to be the big ticket item......

I have been around a few OBD0 (1988) Honda ECU based builds in the 500-600whp range. OBD1 (90-95) Honda ECU's running boosted builds well into the 800+whp range along with 500whp N/A..... so what does this 2012 ECU have that's so new and bad ass?

If you say fuel economy for a 723hp ZETEC engine. I'd be impressed.

Either way they make the same HP , people that have added the COP and made the exact same HP have proven that

The Focus offers both a MAP and MAF ECU combined no but who cares if there combined there not going to both be used at the same time , MAF in my opinion is the only way to go

Im guessing your talking Pulse Width Modulation ? Sometimes what you think you need isnt always the best

Basic builds ? I have SCCA Champion Caterhams and rally cars with stock ECU out running $1000.00+ standalone ECU with full NA builds and turbos full builds , I made 723HP to the wheels with the stock ECU on a Zetec , I wouldnt call any of these " basic builds " ?

Really ? Focus ECU comes both MAF and MAP and I work often with both of them , In the last 2 months I have worked with the new beta AEM , Emerald MD3K , Petel T6 , I rarely use ms as I feel it is the cheapest and lowest on the list of standalones to use so if some one asks I steer them away from it , I am very open minded about tuning

The stock ECU in no way limits the full potential of what the Focus engines are able to make , I see the Zetec and Duratec all the time with standalones and they make with in 1 HP of the stock ECU with the same mods , If you feel the stock ECU limits the full potential of the Focus engines then your are the one that is brain washed to the potential of the stock ECU

It will be 10 years before we see a standalone that equals the 2012 ECU in speed and accuracy and its ability's 30 years before ms has anything equal

GhostTribute I agree, tuning is key!

Yeah MSIII has a few different algorithms available for tuning ITBs. There is the MAP/MAF and they have an actual ITB algorithm with a convenient table that you can adjust for smoothing out the switch back and forth from TPS & RPM to Load and RPM.

iminhell Oh I know what you have going together.
Remember, I said I sandbag.
LOL

But no, I think yours will do pretty well. It's all going to hinge on the tune though. After that it's the fuel that's going to really limit you. The race fuel will be a vast difference from pump 93. Like night and day difference.

The hard part is going to get the tune to react fast enough to the ITB's. That very fast pressure drop can be a PITA with a MAF. And with that, getting it to not bog when you stab it.
But once dialed in, it'll be a really fun ride.

Sanbagger eh..Least I know what I'm up against. Those are some really nice numbers

I don't have a build thread here on this forum and I obviously don't have any dyno numbers ,so here is my project as it sits in pieces;

- 70mm Pro-M MAF housing
- Granatelli Motorsports tuned MAF sensor
- 48mm Individual throttle body w/SVT intake setup
- Custom Air box and CAI
- Dual stage fuel injection system
- 8x 24lb injectors
- K series COP Fully sequential ignition
- Lvl. 2 Comp Cams
- OBX-R 4-1 equal length header w/Cat delete (This will probably be changing to a custom long tube tri-y)
- Magnaflow 2.5" exhaust
- Port, polish ZETEC Head
- +1mm exhaust valves
- 87mm pistons x 88mm stroke
- 12:1 compression ratio with 0.988 R/S
- On 93 Octane, probably run some VP 116 for a run or two for this comparison.
- Will be tuned on an MS III/Extra engine management system.

Just one question though...why would you need to retune if your car is already tuned?


I sandbag.
Simple as that.

and here are my #'s from ~2 years ago --> http://www.focusfanatics.com/forum/s...6&postcount=12
It's changes since then.

So it's for emissions only... So Formula 1, NASCAR, GT, Prototype and pretty much every other form of road racing uses COP ignition only to comply with state emissions regulations then? It's all about fuel economy and power control. It's a higher resolution of tuning capabilities!

There you go you answered it yourself, that is why manufacturers started switching so the OBD would have a higher degree of ability to tell what is going on..


I'm sure if you did some research that you would find there are other manufacturers that use wasted spark ignitions, and they probably use it to burn any unburned gas or or whatever is left in the combustion chamber to help with *gasp* emissions.
