pmccut's FBM dyno results
 

Just picked my car up from WORKS motorsports in Sonoma, CA after adding some goodies: ClutchMasters FX300, Perrin engine mounts, Perrin rear shifter bushing, and Perrin transmission support mount.

I'm e-tuning with Visconti. This is the fourth map so far. The fuel pump (dw 65c) had 2 o-rings and no white spacer originally, so I added a third myself, and WORKS just added the 4th before this dyno run.

I'm waiting on FullBlown to send over a map for the 3BAR sensor as well, and plan to see if LJ can get the car running OK.

The dyno run is absolutely terrible - 179hp, 180lb/ft

Here's the really worrying plot - boost/afr.

Right before the car goes into boost it goes really lean, then super rich.
I have yet to drive this car fast, or even on a fun road. Someone keep my hopes up please

Seems like a tune issue. No worries. Talk to John about it. I am sure he will get you running tip top in no time.

Why don't you flash in the base tune that Full Blown supplies with the kit?

How long has the car been in this condition (waiting for a proper tune)?

Considering another Full Blown kit hit 13.7 with stock tires, it has to be the tune.

The results really are all in the tune. I don't know what to say because my Visconti tune was running nearly twice the boost you are running.

The base tune I had from fullblown was for the stock MAP sensor. I emailed LJ on Thursday for a new tune. Ill bug him again on Monday.

Have you considered going to someone closer to you to do your tuning? It's a bit easier than the back and forth stuff. I know I had some issues with the fuel pump myself.

91 base map isn't that great either to be honest. Red line is base. I was thinking I was going to need to upgrade the clutch--not so much. (dyno dynamics)

After a bit of tinkering this is the best that we could get out of 91 octane and a stock exhaust. California gas is crappy. A bit more than what the innovate kit puts out on this dyno. (mustang dyno)

Wasn't he on 10+ psi and E85? I know he has a built engine with 9.5:1 compression, so not exactly a straight comparison...

listen to King Tut. hes got his FBM kit running great at 320WHP and 260WTQ (give or take)

Looks like you are local! Where are you located? I have to see your car please!!!

Dude, you've met me! I'm pretty sure you were at Stone. I'm out in Escondido. You're welcome to swing by any time.

No, I wanted to go, but couldn't get anyone to work for me :bonk::bonk::bonk: I hate my life

The back and forth is going to take some time, hopefully it wont be too long and you can get that running smoother.

The pump that comes with the full blown kit also needs the spacers? Where can I pick those up?

I certainly considered it. The owner of WORKS does ecutek/brz tuning, but he hasn't done a FBM kit yet. I went with Visconti since I plan to switch to E85 as soon as I make sure I have a good 91 map to fall back to. I imagine I'll go the flexfuel kit as well.

I haven't actually seen anyone posting good power levels for these kits on 91. I really just want to see my AFRs around the appropriate area, so it doesn't have knock correction everytime you enter boost - crazy. Can't wait for some corn

I believe you're supposed to use the one from your OEM pump. I just took my FBM pump w/ OEM spacer out of my trunk when I got the car back today. Wish it had fit as well as the DW65c.

9.5:1 yes but only on the 7psi base map and 91 Canadian pump gas. The lack of compression actually made is worse on the base tune, too much fuel and no timing.

Well don't you have the stock map??

Have you dynoed it?

wow thats bad

i was making 250 whp at 8psi with johns tune and i thought it was not good at all.

talk to LJ @FullBlown he will get you a nice tune

240@6.7 psi. It's since been cranked up though....

I assume that's on a dyno jet?

I'm gonna say yes. Not 100% sure what brand Lj runs

I will adjust it and send it over :)

I know you will get it right ;)

I saw your car last week while your clutch was being installed. :)

May I ask why you just did not have him do his own custom tune?

Is that a stock VS tuned turbo? or Tuned turbo VS non tuned turbo? Because if that was bone stock vs turbo that TQ is way higher than mine :P

Pete's/Works dyno rates quite a bit lower than most. I think it is like 8-10% compared to my other tuner using a mustang dyno.

But I really think 91 is what's killin us. wen we go FI on my girls FRS we will be going to e-85.

Here is a pic of of the frs dyno with a cat back muffler and intake VS intake, boral headers, up pipe, front pipe, catback with tune.

Here is a pic of the dyno from my other tuner same vs same

Also I noticed you still have stock over pipe and front pipe. Changing them out may help as well.

He always does

Update: Got a new map from Visconti early this morning. He wanted a pull on map 1 and 2. I drove around for a bit and got a couple pulls in on map 1, it no longer had hesitation going into boost, but was still much leaner than I'd like. Cold starting was completely resolved as well. On the previous maps the car would stall out unless you gave it constant throttle for 30 seconds.

Now the bad news...switched to map 2. I tried going into boost a couple times and noticed my AEM failsafe didn't show any AF/R readings, as if it was outside of the 10-18 range it can read. Ok..headed home to review logs. Driving on local road, 25ish mph..heard a loud POP sound. Sounded really bad. Car drove the remaining 1/4 mile home and parked the car. Waiting to hear back from John to see if there's anything horrific in the logs.

I discussed it with Pete and he was certainly open to doing the tune. I completely trust him to do the tune, but I bought the pump+e85 tune from Visconti, and plan to stick to E85 once the 91 tune is finalized. I'll probably end up with the Visconti Flexfuel kit so I think a dyno tune from Pete on 91 might be wasted.
Definitely. I'm not looking for high power on this map, just good/safe A/Frs. I don't like seeing my A/F ratio lean out when I hit boost.

Well I hope all goes well for you. Ill try to follow you the best I can. am not sure what fi kit we are going with. But full blown was one we were leaning to. And works is where we are going to have it tuned and likely installed. I kinda like his prototype kit as well. I just wish the flex fuel kit did not cost so much.

if all goes well, the final production kit will debut at 86fest :happyanim:

We gonna hold out for somthin bigger than the stage 0. :) and I need a full time job again.

Why did you put it on a dyno if you didn't feel it was running right?

It was probably way rich would be my guess, but as I have mentioned before, the advantage of the AEM Failsafe gauge is that it stores your last 3 hours of driving, so you can pull the data and look at it if you weren't datalogging with EcuTek.

If you have it installed and configured correctly.. and i imagine a lot of people don't :thumbsup:

I'd like to see the datalog of that pull if you have it.. I'll shoot you a pm.

Honestly - I didn't realize they were putting it back on the dyno. When I brought it there for install over a month ago I asked them to do a before/after, but we ended up not doing one for that reason. This time I brought it back for clutch, engine mounts, fuel pump re-install w/ 4 o-rings. They wanted to see if it resolved the fuel starvation I thought I was seeing. I didn't realize they had until I got there.

I do believe the gauge is configured right as I've pulled logs off it before. I was logging through ecutek so I haven't had to look at the AEM logs lately. Was only using it before my cable was sent.

I was logging through EcuTek the whole time, I'll shoot them over to you.

map sent

afr logging
 

Sent you a ~10 minute log with a single pull, plotting af/r vs boost with the aem gauge logs. Only saw -1 deg knock correction going into boost.

http://emopride.net/squirrels/aem-fb1.png

And here's the most recent map from Visconti.

http://emopride.net/squirrels/aem-pull2.png

Both of these are quick pulls stopping at 5k revs. Now that I know how to use aemdata I can probably scale these better for future logs.

Neither of those AFR curves look all that great, but I like seeing other people using the useful data that the AEM Failsafe provides.

Absolutely. I didn't know it had data logging before ordering. I do wish the aemdata app was more intuitive. It really doesn't seem to be geared for this data. Lap times, track data, blah.

FBM to the rescue! Hopefully you're up and running in no time. :thumbsup:
