Slow and steady progress

I bit the bullet and ordered the 220/224 cam. Basically the Crane grind though at a much better price. Should be on its way for an 06 installation date. I also won an LS6 intake and injectors on ebay for quite a low price, so that should give me more injector and manifold flow for the cam.

After a day spent figuring out how to wire up the wideband and lying on the 13deg C driveway in London hefting on the narrow band stock O2's (NBO2) I finally worked out what went where and being late Autumn of course it got dark so I had to put the stock sensor back in.

The solution it appears, in my mind anyway, is to locate the LC-1 controller in the cabin and drop the Wideband (WBO2) connector down through the shifter hole as the sensor sits basically at the base of the trans. This will give me easy access to the wideband connectors for efilive and calibration, plus keep it out of the weather. Just the Narrow band inputs to the PCM need to go down under the car and the WB02 sensor. So the next stage is to remove the console. Im going to need to do this again when I get the "ripshifter" which I already have sitting in NZ. Hopefully all the LC-1 controller and most of the cables will fit under the console out of site. I really only need a couple of wires available for efilive. This might be a 3 stage process due to time constraints;

1. Disassemble console
2. Wireup LC-1 in NB02 and WB02 mode
3. Reassemble console

Stage 2 is the one which will require dry weather as Ill need to grovel under the car on the driveway again. Though now I have the wiring figured out and a block connector wired inline things should be a lot faster. The old O2 sensor now has a good dolop off anti-seize on it too so should be slightly easier to get out this time.

I should mention that subsequent to my burst knock adjustments the car goes significantly better at part throttle and off idle driving. I have disabled PE mode which runs at over 60% throttle and higher MAP pressures in order to doublecheck my VE table. I expect to turn it back on soon as well as revisiting my timing tables, as I suspect I may have pulled a little too much out in places. Hopefully Ill have the WB02 in well before then and be on the way to a solid baseline.

I also did quite a bit of smooting to the VE table. It looks pretty stock now, though its a little higher in most area's. Still a way to go though.




It looks like running the car on a dyno for spark tuning is the best idea, its virtually impossible on the street to tune for best advance as you need to hold a certain load and RPM point while adjusting spark to verify maximum torque. Apparently maximum torque is also usually a good way from knock point. I found that interesting. I guess Ill have to find out how much dyno time costs once I get the tune dialed in as best I can. Ill also keep my eye out for a dyno day as Id like a proper baseline.

So next step, wideband install. Hopefully sometime over the next week.
