Honda CX500TC - CX500 Turbo

[abecedarian]

Okay... I thought I had it nailed down but time and reality caught up with me so a little change in direction was warranted.

I'm ditching the PnP slant I was hoping to acheive: it'd be good to re-use sensors if the parts were readily available but they're not. Mating to the stock harness would've been great but I'm not keen on destroying an ECU someone else may need and the wire-in type of mate is mostly impossible to get. Even though I found a suitable enclosure with the mating plug, reality hit me: I'm modding the bike and won't have anywhere to put it and on top of that it didn't make sense to use an enclosure as a harness adapter- since I'm not using the module option and the 'squirt is enclosed and this seemed redundant. But then, finding connectors to splice on the 'squirt's wires in order to interface with things was also proving not so plausible. The injectors use what looks like EV1 type plugs but the coolant and temp sensors are similar yet keyed differently and those have been problematic to locate. So generic CLT and IAT sensors are going in too. The TPS uses an odd connector so I'll halve its wires and solder it to the 'squirt's harness.

So, I'm going to ditch the baro option and use a 3 bar MAP: the bike boosts 18-20 stock and if I get good results the boost will go up and an intercooler may go in so the added headroom above a 2.5 bar sensor would be nice. I assume the turbo will provide some compensation as well should I go up in altitude: the wastegate begins opening around 16psi so if air pressure drops the wastegate should hold closed longer. WBO2 should catch the rest. I am keeping the factory water temp sensor and put a GM IAT sensor in the surge tank. I am stuck with the factory TPS until I can find a suitable way of replacing it.

Barring something drastic happening, the trigger will be pulled within the next 2-3 weeks and I would love some advice as to what people think would be the best approach for tuning: speed/density, alpha-N or blend?

And thanks to all those few people who've lent their ears.
