When someone blows a motor as a result of the HT or it's proven unsafe.
Probably never sums it up, though.
You don't think it's happened yet?

LMAO. If you tune the car, and everything is good, you don't just 'develop' detonation down the road, it doesn't appear out of nowhere unless you use s*** gas, and if you do that, it's not the tune's fault, it's your own. Also, the accessport does it's own datalogging of all possible params, well more than I had in my log above. But hey, if you tune it, run a datalog to check the tune, and see kr, then you go back, pull back on the timing, and you're fine. Oh, and if there is severe knock, the ECU pulls timing by itself to prevent detonation.........you know, because it's sophisticated. But I'll talk sophistication later. Regardless, someone doesn't need to **** around with ignition timing to make decent power on stock turbo with pump gas. Use an OTS map, do a couple MAF calibration logs. Calibrate the MAF, set AFR targets to 11.8:1 or 12:1, up the boost and wastegate duty cycle to hold boost on the factory turbo to redline better (only the '11's and '12s so far seem to hold more than 20psi to redline.....turbo upgrade we think) and you've already made leaps and bounds in gains over the HT. And you haven't touched ignition timing or VVT, or anything else, really.
Tec II more sophisticated than the FACTORY ECU in the Mazdaspeed? You pretty much just blew your credibility on mazdaspeeds right out the ******' window. AP isn't the control of the car, it's a reflash/tuning tool that allows you to flash tunes to certain tables on the factory ECU, and not even all tables as Cobb is constantly working on getting access to more tables as it sees fit for users and as they further crack the ECU. Does the TEC II handle a direct injected car running fuel pressures at/above 1600psi at WOT? With individual coils per cylinder allowing ignition control DOWN TO THE CYLINDER? pshh. Right. And a miata ain't no MZR DISI, so don't even compare them. We're running factory MAF/MAP combo, etc. Tell me, can the TEC II hit specifically targeted air fuel ratios just by calibrating a MAF?
Also, it's obvious you have no experience with the Accessport, but in it's various uses, R35 GTR's are tuned to make over 1000whp via AP. Cobb knows exactly wtf they're doing, and their support of this platform is, frankly remarkable. Accessport has pretty much made tuning something anyone with patience can do successfully.
Btw, I'm not a vendor.
I guess you need to go back to school TO LEARN HOW TO READ AND WRITE!!! Seriously, you "lost" me with so much wording and no much essence.
I never said TECII is more complicated than the MS3 ECU... In fact it's a STANDALONE ECU that replaces the factory ECU but this WAS IN A MIATA... not a MS3. For the MS3 there just a few options of a "piggyback" and that's about it. Have you ever tuned a car with a STANDALONE ECU? APs and even the BEGI options are "child's play" compared to that.
But going back to the MS3 discussion, I do have experience with the AP and it's a great device, customer support is top notch and they know what they do. I just don't want it now... For $300.00 that I paid for my used HT, I am very very happy and allows me to get other mods with the money I saved. It's my DD so I am not planning on doing any engine or turbo upgrades.
I looked at the log posted in here by the fully bolted HT owner. Then I went back and looked at my pre-big turbo logs on accessport. He's hitting MAF flow in the 220's g/s. Which is absolutely terrible for the mods he's got. He should be in the 240s+. Shoot, my crap tunes with just intake, downpipe, and fp internals with the accessport and stock intercooler I was in the 250's g/s. Which means I was flowing a LOT more than him, therefore making a bit more power, too.
Paul... dude, your sig is enormous. lol
MSMS3: I had a long response written but the webpage failed on me, so I'll touch on a few points.
Post up for me where Garrett talks about what you said, regarding g/s equalling that much power, generally. Because i can guarantee with the first log you posted, that was NOWHERE near 300whp. Especially not with those mods and boost tapering so low at the top end.
go download virtualdyno. It's free, and fairly accurate on 3rd and 4th gear logs on our cars. You'll plug those in, and making sure you're not using dumb correction factors, you'll see.
Second log you just posted, where the hell are the AFR's? And where's Ignition advance? I can't see either. What i do see is your g/s is in the 230's now, which is still terrible for your mods. Absolutely garbage. I also see you're pulling 13psi to redline, which is better than 11, but still terrible. I will again post later my logs with essentially the same mods as you, bad injen CAI, ebay TIP, stock CBE and TMIC, 3" downpipe, and I was making g/s and flow significantly better, with better afr's (and therefore better MPG under WOT), and boost held much better to redline.
Running more ignition timing due to running richer? well, it's really not helping you that much, because there's still a bit more unburnt fuel coming out, hence the rich afrs (which I can't see in your log anyways) you're apparently getting. If you want to get more power from timing without being stupid rich, run some e85......oh wait, you can't take advantage of e85 with HT. Anyways, I'd like to see that 18* timing advance on the top end.........because that's unheard of on 93 octane without methanol or e85 on these engines without detonation.
I think the problem is, you're trying to argue where HT is better. Frankly, it's just easier to install, that's all.
But let me put this to you. If you installed your downpipe, how long did it take? 3? 4 hours?
If you spent 1-2 hours tuning your car with an accessport, you'd gain more horsepower than you did simply with the downpipe itself, plus you wouldn't be greasy, sweaty, and have cuts/bruises all over your hands and a potentially stripped o2 sensor like many other ms3 owners have gotten. And I'm not talking a ragged-edge tune, I'm talking an 11.8:1 afr at WOT tune with some decent ignition timing, solid boost to redline (tapering because stock turbo sucks beyond 5500rpm) that doesn't drop to 13psi. This would increase your midrange/top end significantly over stock, and it wouldn't be AS necessary to short shift when visiting the 1/4 track.
Even with a good tune, I still had to shift at 6krpm to break 13s in July on stock turbo. It just sucks after 6krpm.
^^^^^^^^^---- alll of this = WINNING!!!
