Last night I wired up the narrowband O2 output from the PLX wideband controller to the Haltech. As I was setting it up in the Haltech software I noticed it actually will accept a 0-5v wideband input, not sure if it's worth re-wiring it though? In any case it didn't seem to be doing much, I could see the sensor voltage on the laptop and the numbers looked pretty much right but I couldn't see it having any impact on the AFR when I went for a test drive. I'm probably not setting it up right, does anyone know how this stuff is supposed to work?

RA65 Celica - the wedge of cheese

I went digging through my stash today to see what Supra brake parts I have. Looks like I have the complete trailing arm setup, with handbrake cables intact which is important because they're different:
I don't have discs but hopefully I can find a pair of new ones (although they were hard to find last time I went looking which was a long time ago), but more importantly I couldn't find calipers anywhere. Fortunately a guy on the Toymods facebook group had a pair he was willing to sell so it looks like this could be a thing after all!
I also found this in my pile of junk, the factory LSD diff out of my Supra:
This will be a direct swap into the Celica and it could definitely use the extra traction, it's already doing single peggers in the first three gears when it comes on boost.The only thing making me hesitate is the gear ratio - the Celica has 3.58:1 gears which is a good match for the low-revving 22R, but the Supra diff has 4.11:1 gears which I don't think would work very well at all. Obviously I could pay a diff shop to combine the two so I get a 3.58:1 LSD, but I have to think about if I actually want to spend the money or if I'm happy doing single peggers everywhere.

I took the wedge of cheese for a drive up to Toowoomba yesterday, its first major outing since I got it back on the road. It handled the task pretty well, and while it is fairly noisy overall it wasn't too bad cruising on the highway at ~100-110 km/h.
Some observations:
- The speedo is borked, it reads at least 10 km/h too fast but far worse than that at higher speeds, ie it's not a linear error. Not sure what could cause that?
- The AC works well on the highway but it struggled in traffic on a relatively hot day. I think I need to install an electric fan sooner than later.
- The front suspension feels terrible, I need to get rid of those chopped springs stat! It wanders around a fair bit on the highway too, pretty sure it's in dire need of a wheel alignment.
- Going up the Toowoomba range there was a boy racer in a lowered late model Golf thing zipping up the hill at speed, I wanted to embarass him in my shitbox (definitely would have chopped him) but the engine pinged pretty badly as soon as I loaded it up. Not sure if this was the hot weather or the fact I was loading it up more than I ever have previously, but in any case I had to let the Golf go to avoid grenading my engine.That tune can't come soon enough!
On the way through Withcott I dropped by John Abbott's place and ogled his ex Group A MA61 Supra which was extremely cool. He very generously donated a pair of MA61 rear calipers which is the missing piece of the puzzle I need to do the rear disc conversion, so it looks like that's going ahead now!Norbie!

the cable inside the speedo tube needs regreasing methinks - 35 year old grease is a little cruddy

I'd guess the speedo gear itself isn't correct? And would actually be a linear inaccuracy (the inaccuracy reported on the gauge increases the faster it turns)?
When I changed diff ratios (3.07:1 -> 3.9:1) I had to wait a day or two to get it sorted (in the ECU in my case). The 0-'180km/h' speeds were impressive

Did it read wrong before the conversion? Nothing has changed that should affect that has it?Previously known as Lobster, Chuss's brother's anus, Chuss's brother, Lobsook, Lobstersock, Socks, Sockz, MissAmericaImportGirl, ClutchCLobster
