SINGLE TURBO UPDATE:
Not much to show at this early stage in development. Currently getting the manifold flange CNC cut by the machine shop. So we should get it back later this week and start putting the rest of the manifold together. We determined were the turbo will fit and what turbo we are using. Once we get it installed and buttoned up a bit, we'll show more pics. For now, all we have is a depressing picture of my engine bay without turbos.





DEDICATED FBO MAPS
While I was at the fab shop, I decided to put a customer car on the Mustang Dyno. Rarely do we dyno 2wd cars on this dyno since it's not what people are used to seeing. The car belongs to SIHK335 on this forum. It has Full bolt ons with secondary cats. As well as a PWM meth kit. It is also a 6AT with 50k miles on the clock.



Since people on this forum have been hankering for a more aggressive tune specific to full bolt-on guys, we got started. So here are the changes I've made to the currently available maps and will be testing for the next week or so in multiple cars:

1) Increased meth dc% from 80 to 100%. This is just a safety precaution since we are testing on CA91oct fuel. I didn't see any knock retard when running the default meth dc tables. But I'd rather play it safe.

2) Increased low/midrange boost to 17-18psi. This is a big change from the 13-14psi we ran before in that RPM range. Boost target still tapers down to ~13psi up top.

3) Enriched AFR targets in the low end/midrange to somewhat offset the heat generated by the big boost levels. By 3000rpm, AFR is 12.8:1. By 4500rpm, it's 12.5:1. Up top, it richens up to 12:1. This is pretty conservative given we have meth for knock suppression. But it didn't hurt top end power too much so we ran with it.

4) Adjusted the IAT based ignition retard to offset some of the retard that the DME induces when IATs is between 40-55C. This really only applies to when not running the meth map. Which we will be testing tomorrow.

5) When meth is flowing, we are still taking out a couple deg of timing in the 4000-4500rpm range due to the high boost. But we are also adding in up to 2 deg of timing between 5000-6000rpm, as boost starts to taper off. Makes for some pretty good top end power with no knock down low.

Ambient temps were 80F so there was no positive corrections for weather were applied. So what you see is actual power. Vehicle sim mode was used instead of fixed rate ramp up to simulate realist accel rates. The last stock car we did made 232-235whp on this dyno using the same settings. So it reads just like any traditional Mustang Dyno with no additive corrections. AFR was feed into the dyno computer from a tailpipe mounted Innovative wideband unit.

After an hour of tuning, we ended up with the follow 3 consecutive test runs:


383-385WHP
453-455LB-FT

Car was definitely hot after 30 runs it did but unfortunately I ran out of time and was not able to do any cold engine glory runs. Perhaps it would make a few more hp once it had a chance to rest. I plan to re-test on a Dynojet tomorrow and see how it relates to dynos numbers that we all more familiar with. I'm guessing a well over 400whp with nearly 500lbft of torque. It engages traction control in 3rd gear

I'll be going back to do some non-meth runs on just plain 91. I'm guessing them will make maybe 25-30whp and 30-40whp less given the fuel quality her in CA. After that, we'll release the maps, in beta form, to the public. They really aren't that different from what is currently out. But this big boost approach is a pretty big departure from what we are used to doing.

Here are a couple datalogs from the drive back to the office:



That's it for now. Got some more updates for you guys later this week

Shiv, did you datalog afr off widebands? If so, could you please share those readings?

[Skydive]

I'm reminded of the old Bud Lite commercials, but instead of the "Less Filling!", "Tastes Great!" arguments, we have less timing, more boost!

I prefer the more timing approach.

[chrisw335i]

but anyways..lol..i am highly anticipating a single turbo upgrade..do have a question though..does this new aggressive v5 firmware and maps affect us fbo guys without meth, or is it partial to meth?

The AFR curve is on the dyno graph. As mentioned in the first post, it was provided by a tailpipe mounted wideband from Innovative. Unfortunately, the wideband scaling was not showed in the Y axis of the chart. But you can make out what it is by looking at the numerical info provided (min/mix/average). Basically mid to low 12s from peak torque to redline.

The AFR logs in the datalog, as usual, are from the factory widebands corrected for the wideband bias voltage. I did not feed the Innovative wideband signal into the Procede if that is what you are asking.

Ready to see where this goes!

[themyst]

Yeah, I was referring to the Procede logs. Thanks for the clarification.

Me too But luckily in this case, we have full timing and more boost. Made possible by more meth as well.

It will apply to non-meth guys as well. But it's the meth guys that are going to get the most bang so to speak. And we are talking 40-50lbft more in the midrange than the current maps. Non meth guys may "only" see 20-30lbft more.

I was seeing mid 12's and up throughout the entire powerband on this beta map.

And didn't seem to see any post-shift timing drops while running the meth map.

That was kind of surprising.....but it may be to early to say it's gone.

But there is definitely some different fueling going on here.

Thanks for testing Ilma. I can always count on you

Do you have an external wideband like an LM-1? This is NOT meant to troll, but the AFR figures generated by the Procede logs are a calculation, not actual AFR. The AFR figure within the dyno sheet is definitely plausible though.

.

Tell me about it!

Almost 18psi on stock exhaust and I still had ignition advance up in the 10's with just a single dropout in 3rd.

Bit too much for stock exhaust setup....but not bad considering.

Lots of thrust and momentum for sure.

But look at that post-shift timing. Don't see it that high on my car too often.

Yeah...but I think the point Shiv is making is that they are pretty close to each other.

Definitely too aggressive for stock exhaust but still pretty surprising. Funny what another 20% meth flow let you get away with

[Overboost]

Nice Shiv. Hopefully you got the email i sent you today with one my recent logs and dyno.I'll be glad to do an independent dyno for you of these maps and compare them to the old ones you released.

I didn't even realize the part about the extra meth flow until I read this post

Just saw you email a few min ago. 410whp on pump aint bad You have mail.
