devil on your left shoulder….. pssst, yes you must do it. you must do it now.
August 19, 2019 at 4:47 pm #208424toys-n-yotasParticipantHmmm, still waiting for the devil on the other shoulder to chime in.
Picked up and installed a new AGM battery, we’ll have to wait and see if this cures my starting troubles.
August 19, 2019 at 5:58 pm #208425finn the kareilian vikingKeymasterok then…why’s it not done yet?!?!
August 21, 2019 at 6:51 am #208427toys-n-yotasParticipantHaha for the exact same reason that I have boxes of uninstalled parts. Weather is too nice to stop drivin’ and start wrenchin’.
Install my new steering parts and pay for an alignment are on the shortest list.
The AGM battery has helped a lot, but I still had one no-start yesterday. But still better than with the old battery. Perhaps the starter is also a culprit.
August 21, 2019 at 5:29 pm #208432toys-n-yotasParticipantUpdated my fuel log. My last two tanks were both exactly 17.6 L/100km (13.4 mpg). This improves on my previous best of 20.4 L/100km (11.5 mpg).
Hoping an alignment, some fresh diff oil will help me crack into the 15s.
To keep it in perspective, my first few fillups were about 24 L/100km, which is less than 10mpg…🤪🤬

August 24, 2019 at 7:45 am #208439toys-n-yotasParticipantDid a little camber adjustment by eyeball to reduce some of the wear to the front drivers tire. I was pleasantly surprised when I was able to adjust the lower control arm cam bolt! I only tried to adj one, still 3 more potential headaches haha
I ordered upper and lower balljoints cause the lowers have some play in them. Once the balljoints arrive, I’ll work on replacing all the front steering parts.
August 29, 2019 at 8:51 pm #208449toys-n-yotasParticipantUgggggghhhh EFI tuning took a dump on my way home from Point Clark (Lake Huron 40km N of Goderich).
My girls and I set off from the beach for our ~90mim drive home. The first 60 mins were awesome, 90km/h speed limits, est cruising speed about 100km/h…I kept it under indicated 90, cause I’m out about 16%.
After an hour, I was forced to slow down. Anything over 21.2% throttle input (as per TPS readout), and my Air:Fuel ratio spiked, HARD. I can maintain an indicated 82km/h at that throttle %. Below that threshold, redee ran fine around 14.2-14.5 A:F depending on load. Anything above 21.2%, and no additional fuel was being added. A:F hit 15-21:1!!! Super lean, fall flat on your face bad tuning.
Twenty minutes later, my threshold was lowered to 19.4%, and speed dropped too, indicated 73km/h.
I pulled over, opened my gas cap as I thought, “maybe, just maybe my tank is being sucked dry and relieving the built up vaccuum would help.” I was wrong. No change.
Getting back up to speed at under 19% throttle is tough. Then the threshold lowered again to 17%….
We limped the remaining 15km home at an indicated 60km/h (about 70 actual).
Upon arriving home, I reset the EFI fuel and TPS learning, and instantly Redee was cured of the Super Lean condition.
I’m afraid Redee smells like a tractor, and once again, is well over 20L/100km.
Lesson learned? Very very small increments on EFI tuning, and RESET the IAC Steps, which link the learned fuel map to the Throttle Position Sensor.
August 31, 2019 at 12:17 am #208451Slick_YotaKeymasterQuestion: when you adjust the cam bolt, does that not throw out your toe? I think it would have less affect on camber than toe…
EFI issues sound like way more effort than I’d be willing to endure – kudos to you!
August 31, 2019 at 7:56 am #208455toys-n-yotasParticipantSlick, you’re correct on the lower cam doing camber and toe…and my toe was OUT too. Both seem improved with some arbitrary eyeball adjustment that I made, but alignment is on order.
My upper and lower balljoints arrived, also all my steering bits. Now just gotta put in some wrench time.
These efi issues were self inflicted. After 2000km of learning, I changed the targets without recalibrating. Stupid rookie mistake haha.
September 1, 2019 at 5:20 pm #208456toys-n-yotasParticipantDid a little work on Redee after my buddy and I ran into more Fuel starvation issues. We hypothesize that as the fuel pump warms up through use (and proximity to exhaust), it stops being able to keep up to demand. I removed the secondary pump on suspicion that running it dry ruined it, and plumbed it out of the fuel run. I also rewired the FiTech EFI to send signal to the OEM tank pump which is brand new with rest of fuel system. Only the secondary pump is old, and now it’s gone.
25 km down, and no A:F concerns yet. I figure if some 0-100km/h rips couldn’t create an underfuelling condition, only tuning can be my demise now. Fingers crossed.
Also removed the last of the old Holley Projection system by pulling the paperweight-like computer from the glovebox, freeing up half the space.
Also also re-ran the EFI module the opposite way across the firewall and through a grommet so it enters the cab on the drivers side. Added a ziptie to the holder thingy so that it stops falling down when I hit the washboard roads at 70…
Good day in the shop, and no gasoline in my face or armpit!!

September 15, 2019 at 3:58 pm #208480toys-n-yotasParticipantThe epic battle of Free Time vs. Expendable Cash just took a sharp left turn…..I left my job to pursue new and interesting things, hopefully earn some dollars while I do it. So long oppressive former employer, can’t hold back my creative and technical contributions anymore! Real smart move on NOT asking me to give an exit interview.
Next steps. Dream my dream, and start chasing it.
😎
September 16, 2019 at 9:46 am #208481toys-n-yotasParticipantFall setup engaged. Got the OEM hard top scrubbed and bolted on, the Canback was just too breezy for the kids at night.
I grabbed a free skid from a business in town, and recycled it into a refurbished deck for my roof basket. Free skid, free wood screws, almost too easy. Getting it on the roof, aligned, and bolted up…. much less easy.
Using one massive ratchet strap (10,000lbs breaking strength), I finally hung my spare tire in the original location. Took lots of wiggling and cursing to keep it off the exhaust, suspension and rear axle simultaneously, but I think I managed. The lower bolt on passenger side leaf spring shackle is touching the tire, but I think it’ll survive. Hopefully vibration doesn’t cause the bolt to rub through the tread. Time will tell.
The extra weight (spare tire, hard t0p, roof basket) on the rear axle has helped to smooth the ride out some, and has gotten me another batch of “Cool Points”as determined by a recent increase in Thumbs Up received (real life, not facebook crap). Roof basket for the win!
September 18, 2019 at 6:32 pm #208486finn the kareilian vikingKeymastertom, kudos on kickin’ the oppressive dictator to the curb man. good fortunes towards employment that boots your creative mind into full throttle.regarding exit interviews, mine usually went akin to this…fahque u, i’m outta here. but what is your reas….yeah, i’ve not got the time nor the crayons to explain it to you. exit stage left
i like the ol’school look of the roof rack by the way.
September 28, 2019 at 12:56 pm #208502toys-n-yotasParticipantThanks Finn! I legit had some positive messages to spread, and a to-the-point where they fucked up, but they’d rather keep their ego in check. “We have a plan, can do just fine without you.”…. So good luck, and good riddance MF’ers!!!
Haven’t completed any tasks with Redee of late, but still enjoying a cruise off-and-on.
I am pushing to get an ATV finished up so I can sell it. Checking back to my notes, last time I touched the ATV was Feb 25th….was waiting on parts (till April)… anyways, got 7-hours put in this week, and getting close to finishing. Needs some fresh fluids, torque check and a spit shine. Hope its on the selling block this coming week. Tired of looking at it haha.
