I am using the stock target loads. If you have a stock evo 9 rom then you have the loads I am running.

One question, though, I was under the impression that the target loads are to be left stock until we modify the boost with the pill. Can we change the load target w/o upping the boost by changing the WGDC settings?

 

Here are the HPTQ values from my calculator. The numbers are a bit lower than DLL, but show the same trends.

 

The stock ROM uses two different target load curves. #1 and #3 are identical and less aggressive than #2. It seems reasonable to assume that the ECU uses #2 after warmup, but, in the instances that I've seen, it does not. Your log data are below with both sets of target load curves. Your stock run is on the left. Your TBE tune is on the right. For both runs, the ECU looks to be pulling back boost when the load shoots past the target load during spoolup. That indicates to me that the ECU is using target load curve #1 or #3. Don't know which or why.

Anyhow, to answer your question: yes, no reason why you shouldn't tinker with the target load even with the stock pills. You could probably achieve a more consistent load curve if you changed the BDEL tables #1 and #3 to match #2.

BTW, it looks like you've moved the leand spool disable rpm out to 7500 on your tuned ROM.

 

mrfred,

Could you tell me the peak hp and torque and the rpm associated with them?

 

If you mean the HP/TQ for your logs, I posted those already in the post above the one showing the load, etc. Otherwise, I don't understand your question.

 

I am talking about the actual numbers, for example, in my chart it was 292 hp @ 6594 rpm and 272 lbft @ 5047 rpm. I cannot tell from the chart the actual numbers. I am estimating it is 270 hp for the tbe run. Could you do that for both the base and tbe runs?

 

From my calculator:

Stock: 245 HP @ 6110 rpm, 242 ft-lbs TQ @ 4330 rpm
TBE tune: 273 HP @ 6900 rpm, 255 ft-lbs TQ @ 5350 rpm

The peak TQ value for the TBE tune is at goofy rpm because the ECU pulled back boost at lower rpms where the peak TQ should be.

 

So here is the breakdown per power calculator for my car:

Evoscan
Stock: 281 hp & 265 lbft
TBE: 306 hp & 284 lb ft
Delta: 25 hp & 19 lb ft

Dataloglab
Stock: 258 hp & 255 lbft
TBE: 292 hp & 272 lbft
Delta: 34 hp & 17 lbft

mrfred hp/tq calculator
Stock: 245 hp & 242 lbft
TBE: 273 hp & 255 lbft
Delta: 28 hp & 13 lbft

DLL is most generous on hp while mrfred's is most conservative on torque. Evoscan is most generous on torque and most conservative on hp

 

mrfred's seems to be the most realistic, at least compared to what I see on the mustang dyno.

273whp sounds about right for you still being on low boost, and 245whp stock is at the higher end of what stock 9's do on the mustang dyno here. 235whp is average

 

I do not know if mrfred's dyno calculator takes into account the weight of the car or the environmental conditions the car is tested under.

 

It accounts for weight, tire size, gear ratio, and aerodynamic drag. Those values are all adjustable and are in the spreadsheet (which I recently updated to include boost and afr on the HP/TQ graph). It does not account for weather conditions. Cooler weather will likely net more power.

 

Low boost!!! Isn't this high enough on 91 octane gas? This is the latest boost profile that I have. 3 runs averaged.

 

20psi is considered low boost on 9's to me. Of course, it depends on what your evo likes of course.

Didn't you have a bunch of pills made up? I bet you could make a bunch more power and torque if you tuned in about 1 psi more at 6-6500 and 1-2psi more at 3500-4000 if the car likes it. The 9's will take more boost around the peak torque area than 8's will.

You might have to richen your AFR up a little. Again, your car might like less boost and leaner AFR, or it might like more boost and richer AFR. YMMV.

 

Just strap the car on to a Mustang dyno to see where your at that way you can standardize any future log charts. Of course conditions and location need to be constant

 

Is the HFC 2.5" or the 3"?
Is there any neck down on the entrance of the cat-back?
I have a 3" HFC on the way, but my Apexi WS2 catback has a neck down,
and I was wondering if this will cause any problem for a daily driver.
Thank you.
