Apparently the OBDII ECU can support 8psi or so by simply replacing the AFM and injectors, and leaving the programming alone. He said he was very close, and I should call him in a month. (This was mid-August) He didn't comment about the timing issues, so perhaps (and I'm speculating here) the OBDII ECU can learn from the knock sensors and build maps that are good enough for at least this much boost. That said, the primary difference between the BEGI kits and the Flyin' Miata kits is that Bill (Flyin' Miata) adds an ECU and gets rid if the AFPR. It makes a big difference, and is absolutely required when you start thinking about 12-15psi. I can try to get more detail from him; I need to send him another email asking for photos of the M3 kit so I can see if there's a snowball's chance of getting the pieces to fit in my Coupe.

The amount of concentration required when driving at 130+mph is immense and your brain tires quickly. I once did a trek from Hamburg, Germany to the border with Holland (on the way to Amsterdam) at 210+ KPH (120+ mph) in a Passat Turbo Diesel. Let me tell you after that few hours of doing that I was beat (although I did manage 30+mpg!!!) . As far as the engine is concerned I wouldn't worry about it.

Date: Wed, 10 Oct 2001 14:45:24 -0400 From: Vern Anderson <vanderson@cerebellumsoft.com> Subject: Re: A032R Pressures? Drew, I've run through three sets of the Yoko Ono's and I've settled on the following: 26 cold F/R on the left and between 27-28 cold on the right (for a typical CW track like Nelson or Mid-Ohio). I experience about 10-11 lbs increase on the left and about 9-10 lbs increase on the right due to heat. That seems to let them settle in to a nice 36-37 hot on all four corners. My experience is that if you get them over 37 hot, they start to get greasy and lose quite a bit of grip. I've run them on 7.5" rims and 8.5" rims and I've never had any rollover problems - I think they have a very stiff sidewall. Not as stiff as a G-Farce, but way, way stiffer than a Hoosier for example. So the 26 cold may seem low, but the sidewalls will hold up their end of the bargain. The only thing I would add is that my car has a very modified suspension (coilovers, sways, camber plates, etc.) so with a stock suspension, you may have better luck with slightly higher cold pressures (maybe 28-30) because the stock setup will probably not work the tires quite as hard as mine does.

#7. Re: [E36M3] BEGI M3 Turbo (Was "I thought I'd Pass this on") - from Matt Henson

Date: Wed, 10 Oct 2001 12:04:22 -0700 (PDT) From: Matt Henson <hensonator@yahoo.com> Subject: Re: [E36M3] BEGI M3 Turbo (Was "I thought I'd Pass this on") Wow.. that's.. uhh.. interesting. Changing the injectors and MAF sensor will increase the maximum fuel spray but the DME will adapt to maintain the stock AFR. It will use the long term trim from the part throttle (lambda) operation to pull the top end (open loop) back in. It will also, as you say, pull back the spark to eliminate knock. Spark timing on these cars is adaptive so it doesn't have to re-learn the timing every time you start the car. I would think that what's going is that the fuel is similar to stock (a bit too lean for optimal turbo performance) and the timing gets pulled way back to compensate. I think that the stock DME might actually add a bit of fuel to help combat knock so that's good. You'll also get stuck with the stock VaNoS changeover, which might not be optimal. So, yea, I guess I could see it working but I'd seriously doubt that it would get within 5% of a properly tuned setup. There's also a risk of having problems if you can't find 93 octane fuel since there's only so much timing that can be pulled out. Plus pulling back timing increases EGT, which is bad for the longetivity of your exhaust valves, head and turbo. It's always better to get the fuel right and then figure out how much timing you have to work with. -Matt --- Aleksandr Milewski <n6mod@milewski.org> wrote: > Date: Wed, 10 Oct 2001 11:11:48 -0700 > From: Aleksandr Milewski <n6mod@milewski.org> > Subject: Re: [E36M3] BEGI M3 Turbo (Was "I thought > I'd Pass this on") > > I spoke to Corky at the Flyin' Miata open house > about the OBDII M3 > kit.

As you know, cold pressures don't matter. It's hot that counts, and that'll be a function of track and ambient temperature plus the way you drive. Then you back that down to a cold pressure that gets you where you want to be hot. Try starting in the 33-35 psi cold area, but you should come in once the tires are warmed to check. Around 40-41 psi hot is a reasonable area for Yokos. However if they seem to be rolling over too much and wearing the shoulders excessively, don't be afraid to let them get up to 44 psi hot.
