Well that should cause much less unplanned drama.

Another update video:



Watch it if you want to hear me ramble on about nerdy crap for 15 out of 20 minutes of video.

So the AEM fuel injector calibration made my fueling table look really weird, so I rolled back to the ID numbers and it's back to well behaved again.   It's still a little different than it was, but I'm going to chalk that up to changes made in the fuel system while the ECU was being repaired.

Boost control still isn't working, still don't know why.   My assumption is something in the Chinese wastegates, so I'm going to move to proper Tial at some point and put some heavier springs in while I'm at it.    But hey, it does a dead stable 4 PSI really good.   Car still feels like it's falling flat hard about 6250 RPM, I think that might be the cams, but it's a really strong drop in power, while spark/fuel are staying happy, no knock is occurring (sensed or heard) and lambda is happy.   So, probably really need the bigger cams, which isn't shocking as the dyno graphs I've seen for truck cams look fairly shitty up top, hah.

Anyway, so far so good on everything else.   Just dialing things in now.

I have manual brakes in the Mustang and it's fine, but I'd rather have had power brakes if they'd fit.   I'm not sure I see the benefit of this one.

So are you parting the R1 to work on the touring, or building both?   Looks like a lotta work!   :D

The stance on that thing is just dead on.    Looks like a ton of fun in it's proper element, too!

Hah, we're a pretty laid back group around here.   Congrats on getting a car you really enjoy!

I have a few, but absolutely nothing fancy.   A couple Citizens and an old, 1990s Tommy Hilfiger that a friend gave me in high school.

I wear a FitBit now though, so they donít get worn often.

So, good-ish news on the AEM.   I checked my log and it's reading ethanol percentage fine, it's just not outputting it to my AEMnet gauge (which is a real AEM gauge).  I don't know why it's not, it outputs every other channel, but probably a firmware thing.

From my reading, MS3 is kinda like AEM with the issues, but I do like that it costs 50% the price.   This thing I have cost 75% the price of a MoTeC and it sure as shit ain't a MoTeC.    We'll see how I like the Haltech I'm putting in the 2JZ car this winter.   If I'm in love with it in that combo, I will switch over to it.

Hoping for some nice weather to work on the tune.   Turns out that AEM and Injector Dynamics disagree on the flow numbers for my ID1050x, with AEM saying that on the Infinity, the ID numbers are wrong down low.    That's fine, but since I moved to the AEM numbers for them (and kudos to them for bothering to flow the injectors and publish the info), now my VE table is scaled wrong and the car is fat.    Not a big deal to sort, but another thing that needs sorted.

Regarding the sensors, yes, yes, yes, always have a fuel/oil sensors on the engine.   I plan to add a couple more sensors when I redo my engine harness in the near-ish future.     I'll have the following:

Oil temp
Oil pressure (have this now)
Fuel temp (need to get this working on my flex sensor since it's built in)
Fuel pressure (have this now)
IAT at manifold (have this now)
IAT before intercooler
Exhaust backpressure
8 channel EGT (probably... anyway, this is some $$$)

I'll gt pics shortly.

I got the rear end put back together and pinion angles sorted (at least they seem to be).   It was a little "off" before, so I'm glad it was simple, no more vibration (again, in my limited testing).

The TrueTrac is drastically less annoying from my testing so far.    So I'm happy with that purchase.  :)

The AEM read flex fuel normally right when I plugged it in, which was nice to see.   They said it wasn't an ECU problem though, so whatever I guess.   I then flashed the firmware they sent me for it (because I still can't get it from my download site for the ECU, and they don't seem to be able to fix that).    That then caused me hours of work as they sent the wrong firmware, so I then had to go get the right firmware, put that back and get my tune back in it again (it wiped it).   That didn't want to go back in... yada yada, I'm not real pleased.     Odds are pretty good I'll swap ECUs at some point, I'm just not thrilled to burn another 3k dollars on another ECU.    Oh and after the firmware stuff, I see 0% on my ethanol reading.   Again.   The ECU is showing proper frequency for the sensor though, so it must have just borked a setting.

Anyway, I'm going to call them tomorrow and see if I can get someone to get me the CORRECT current firmware.    They keep acting like I'm an idiot and have to be doing things incorrectly, which grates on my nerves a bit.

So, annoyance on the differential.   Turns out I have a 3.250" bearing case (large case) to fit a 35 spline diff.    The Detroit Locker had a 2.00" bearing journal (ID of the carrier bearing) meaning it used a normal "33/35 spline" bearing combo (2.00" inner 3.250" outer).    The Detroit/Eaton TrueTrac uses a 1.781 ID bearing.   That means I can't use a normal bearing and need a special combo (it's just a wider outer race and a normal bearing).   Annoying.   So I'm waiting on that to come.

AEM shipped my ECU back today.   They couldn't find an issue with it, though they did note that it did NOT have the updated electronics inside, so they did those updates for me.   I need to bug them to get me current firmware since I couldn't use the 2016+ release on it for some reason as well.  Hopefully it all works now, especially the flex fuel sensor and the boost control functions.

Anyway, I did repaint my wheel centers bronze, so they're A) the color I wanted all along and B) matching front/rear.

I think I have a stack of stock gray body LS1 injectors in the garage.   I can check tonight if you want them.   Free.99
