Shitty. When I make my harness i'll be making my stock connectors easily reinstallable so I can put the original coils back in as well. The idea of being stranded on a roadtrip just sucks. Did go on a 250 mile trip this weekend to knoxville though, had a good time and the car ran great. 26.6 mpg on a decent street tune, cruising with the afrs bouncing around 14.7-15.5.

went 250 miles exactly, also rolled the odometer past the 60k mark on the way home. still have an indicated 1/4 tank remaining
amazing what kind of mileage you get when you're limited to 7 psi

Yeah i'm still running the 1.8 injectors, hope to install the 550s this week before petit. I too had a quater tank indicated when I got back, appears we got about the same mileage.

install the injectors the weekend after. if you're tuned and issue free, leave it that way before you road trip it.

i think i found the problem with my ignition. i had to crimp connect my main power, main ground, and tach wires because I broke my (late grandfather's) soldering iron when I dropped it after burning my hand.
well, the power and tach crimps failed immediately. this time the ground failed. so something about these 12-14 ga butt connectors is wrong. I have a decent crimp tool and put what appeared to be a good crimp on them. but all 3 have failed. one of richard's wire nut jobs would have been better it seems.

thanks for the pics, wished I was there

I've always gone solder and heat shrink- just don't have as much confidence in my crimps I suppose. And I've got a good crimper too. I had a pro install the ecu in my last race car and he soldered too. Said the same thing- solder is "for sure". He used some kind of heat shrink with a sealant in it... I think it was marine spec.

would have been nice if you came.
we all need to do it. it should be very scenic in about 3 weeks or so.

i think my ignition is good to go again. what i ended up doing is splitting the heatshrink over the crimped connections and I flowed solder down into the butts. that should make them solid. when I was doing that, I broke one of the leads off my resistor that I use to shunt power to tach. so I replaced the resistor and used electrical tape to wrap a butt connector up next to it like a splint.

i'm hoping to get my diff swap done this weekend, maybe my brake swap next weekend... and hopefully I'll be good to go

I will get in the loop soon. My kids need to get a bit older and I need a couple of serious days to work on my car. Just picked up my new oil cooler today with some freshly welded up AN fittings. Step in the right direction.

I figure if the car is built to manage track duty, then it should survive the rest of the whatever is thrown at it. I keep thinking "this will be it" only to find out whatever I changed just wasn't enough. So the process never seems to end.

Short term goal is to get the oil cooler in, so I can rejoin everybody at the dyno. I'm hopes that my peak power occurs later than 5800rpm, and should therefore be much higher.

I "just need" to get bigger injectors, tune them in, improve cooling.....

Gassed up today. The trip was 250 miles on Sunday. Drove 5 miles today before filling up. Took 8.95 gallons. That's about 28.5 mpg
16:1 cruise FTW

Real reason for this post was to ***** out the photo though:

I averaged 25.4 mpg that trip. Some day I'll tune some cruise zones.

I wouldn't say untuned. Just ot tuned for economical cruising. I'm at 14.7 in most cruise zones.

I most certainly was in boost, but not 100% of the drive. I think I can speak for Ben as well.

There was only one stretch before lunch where I was able to really use all my power potential. And I did. After lunch, when it was just me and Ben (the two turbo cars), I was in boost constantly, but kept it under 7 psi because the spark was getting blown out at 7+

Around town I've been getting around 23-24, driving it like I stole it. I'd bet on a highway trip I'd break 30 mpg.

Sounds like i need to tune my **** a little better and turn on overrun fuel cut. I decided to install the 550s today, won't be taking the miata to petit this year i suppose. We have a semi large group going, decided to take the g/fs protege instead. What a buzz kill.
