There’s a pretty big learning curve in the MegaSquirt tuning process. And it’s even steeper without a working Oxygen sensor! My troubleshooting of the O2 sensor has gotten as far as to verify that the controller seems to be working. My guess at this point is that the combination of driving around with the carb [...]
Spent a good portion of the afternoon working on the car. Started with the spark plugs. They were definitely fouled from all the rich idling they’ve done recently. I scrubbed them clean on the wire wheel and regapped them to .050, good enough for now. I decided that I really needed to rig up the [...]
Yep, it’s down to the Megatune software and about a thousand different settings now. That and the O2 sensor. I started today trying to determine if the LC-1 was working or not. Turns out it wasn’t. I had power wired to the FP supply on the relay board… not sure why, but that was giving [...]
Grab a beverage, have a seat, and let me tell you about my day. I slept in until after 10am, goofed off for a bit, then set out to Lowe’s to pick up a couple nuts that I forgot to get yesterday and pick up some lunch at Sonic. Since the weather was perfect, and [...]
Got over to Jeff’s shop today and got my welding done. Not the prettiest welding (I did it, not Jeff), but everything that needed to be stuck together is now stuck together. Unfortunately, I blew the rest of my afternoon helping Jeff work on the brakes on his Cavalier, so I didn’t get anything else [...]
Had a very productive evening banging out the bits and pieces for my throttle linkage. Started with a trip to Lowe’s, as usual. There I picked up some thin sheet steel (I forgot that I had some leftover from the EDIS bracket, oh well), some bolts to replace the buggered up formerly stuck phillips head [...]
Got all the fuel fittings taped and tight on the TBI Wednesday. Also made the mounting studs and Loc-tited them in place. Thursday I bolted the TBI to the manifold. Moving right along. I looked under the bonnet today and still haven’t decided where to mount the fuel filter. The most available firewall space is [...]
Oh yeah, I spent more than a few hours working on a wiring diagram last week. I just wanted something neat and tidy to show all of the MegaSquirt wiring on one page instead of having one diagram for the EDIS, another diagram for the Relay Board, and a master diagram for the MS system [...]
I’ve not been getting a lot done lately, but I have gathered a few more parts and I did find and tidy up the fuel return line on the car. Being an “emissions-equipped” car from the 70′s, it had a vapor return line from the carb to the fuel tank. It’s a rigid plastic line [...]
I did some wrenching today, but not on my car. It’s all good, though. I gave up a few hours of my life and some skin off of my knuckles (tip: never volunteer to change heater hoses on a Honda S2000) to help my buddy Jeff (here comes the plug) of 1st Place Engineering in [...]
