Um... no, I've never noticed that. Euro HFM? Dinan Stage IV or JimC. Larger injectors? AA, RMS, Dinan all have large injector programs. (dinan won't sell their's to you but you get my point.) What else? Intakes, headers, cams, I repeat, the Siemens DME is much more picky about closed loop operation. This is a proven fact. But! it cares just about as much as the Bosch DME about open loop. Why should it be different? Both ignore the lambda system. What else is there? I never said it was easier, just that it wasn't necessary to make good power. The key to a good OBD-II system is keeping the a/f mixture very close to stoichiometric during closed loop so you don't run into problems with long term fuel trim destroying your finely tuned program at wot. That said, it's definitely not impossible! > injectors on there and you'll > make 300HP at the engine. The only N/A way to > get 300 from an OBDII 3.2l is > to do cams.

Most of the obd-1 conversions that I've seen are in the 235-240 rwhp range, with the same amount of modifications I have. You know why? When you switch to OBD-1, you bring the manifold! but, hey wait... the intake manifold works with OBD-II. Hm. Lemme get to the dyno and tell you how much power I'm making with my obd-1 manifold and then we'll talk. I've never seen an OBD-1 conversion make more than 240 rwhp with the same amount of mods I have. (intake, exhaust, chip) I guarantee I'm close to that, close enough to where you'd never tell going down the front straight. I had a 315 rwhp fully smog legal OBD-II car. (supercharged but that's not the point...) Now I have a 230 rwhp OBD-II car. (well, actually I haven't dyno'd with the manifold yet, 230 was before I did the manifold, the fan delete and the M-Roadster boot) I bet I'm within 5 hp of an OBD-1 conversion. And, I didn't spend $1500 to get there. How about Alex at Eurospeed? 264 at the rear wheels with fully functioning OBD-II. (sure, he has cams.) Ok, I won't argue that OBD-II systems are harder to tune. They aren't socketed. They do require either a flash programmer or a socket to be added to the DME. Don't get me wrong, I have definitely considered going to an OBD-1 system, but the fact of the matter is that it makes just as much sense to convert to a TEC-III. You can fashion (or buy) a plug and play connector that just splices in between the engine and DME, and uses the stock coils. (see www.siastuning.com) That gives you a freer flowing intake tract (no MAF) and much greater flexibility. Jim Ochi is making ~265 rwhp with his TEC-III, with intake, catless midpipe, headers, exhaust, and pulleys, I believe. No cams. And, the TEC-III isn't a whole lot more than an OBD-1 conversion. (~$1000 more) And, since the DME stays in place, more chance of you passing smog.

The necking down of the runner size causes flow velocity to increase. Think of a slow, wide river, turning into a narrow gorge. The speed of the rapids gets fast real quick. If you keep the width of the gorge the same, but increase the volume of the river flowing into it (i.e. you're stuffing more flow into the same size funnel outlet) you increase the flow speed. At some point the restriction can't take any more flow and a larger inlet bore becomes counter productive. The critical relationship between inlet bore and the venturi size can be seen in Weber and Mikuni type carbs which have an numerous different choke sizes that can be changed to adjust the width of the carb inlet and thus adjust air flow quantity and volicty.

I am thinking about buying another E36 M3 for SCCA Street Mod, and TEC-III seems to be the way to go. Might as well a start out with the final solution. :-) Here is a link to supercharged M3 that Sias Tuning installed a TEC-III on, 400Hp isn't too bad. http://www.bimmerforums.com/forum/showthread.php?s=a2257605151b8c69c5f2b365d5073949&threadid=65205 Another thing I like about the TEC-III, is there seems to be several people in the Bay Area that know how to tune them, versus Jim C. in Utah is the closest bosch/siemens developer that I trust. -- Rex Tener rex_tener@yahoo.com 1996 BMW M3, SCCA SFR Solo II Street-Mod #173
