I don't have any experience with the Sniper, but from that Holley forum thread it seemed like there might also be a firmware update that goes along with the progressive linkage, to help tame the issue. Not sure about that, but might be worth checking out.

I read through the instructions this morning. They say that older versions (shipped prior to March 2018) may need an update before adding the progressive linkage. For me, it looks pretty simple:

"To complete the ECU configuration, use the handheld LCD display and navigate to Tuning > System > Sniper Setup and set the following parameters:

1. Progressive TBI Linkage: "Enabled"
2. Primary/Secondary TPS Switch: TPS percent identified in step 2, above. (approximately 40% based on TPS sensor position measured after installing the new linkage)

At this point you are ready to enjoy the new, more manageable response of your progressive Sniper EFI System Throttle body linkage!"

In the video link you shared earlier, the guy did a bit more manipulation using his PC to adjust the tune. That made me nervous, so I had to look it up this morning. Based on what I read, I should be able to do it all from the handheld. I'm hoping the part will be here later this week. It's shipping from Florida today.

Holy smokes look at all these posts. Wow I really been missing out! So glad to see you got a Sniper system. Sorry it hasn't been plug and play, but I know you and that will have no bearing on the final outcome. Once you get the bugs worked out it should be invisible and something you can forget about. Wow Grayskies, you been very helpful to his plight. Good on ya.

I think Iím going to try and get the Rogue Fab bender. I think it will orient the pipe when Iím bending in a way that it will be easier to use in a small space. And lots of people love it.
I just want you to know I love your signature line. True words bud and something I will always try to remember.

Glad to hear from you and know that you're still checking in from time to time! Slow and steady she goes.....

Gotta love it when you drive the CJ to work and the guy in the plumbing van that you pass makes a point of leaning out his window and giving you a big thumbs-up! (And no, I did not cut him off; and yes, it was indeed a "thumbs-up").

The progressive throttle linkage came in today. It took me longer to pull the pin and remove the old linkage than it did to install the new one and make the changes to the software. The street manners are much better, as the second half of the carburetor will not engage now until the throttle position sensor hits 44%. Honestly, it’s not quite as much fun to drive now on the street , but certainly much safer and better suited to off road situations. If I really wanted to get technical there is an adjustable linkage available, but I think this will suffice for now. Although, having it kick in at 22% instead could be fun and a good compromise.......

I also addressed my mild driveline vibration by adding shims under the rear perches. This helped roll my pinion angle up a bit towards the t-case output shaft better. It dropped some when I went to taller springs with a different arch. I’m not too keen on using shims, but it was the simplest fix for now (and I already had them leftover from when I adjusted the front). It handles smoothly on the highway now at all speeds........well, smooth for a CJ anyway.

Please share some of the photos of your Jeep when you have time. I briefly reviewed most of this build while doing research myself for swapping a V6 to V8. I see you ended up going with the T18, right? I recently purchased a 1975 CJ5 and from your profile picture I like what I see. Building a 72-75 your options for certain parts are limited so I'm looking for ideas. Thanks for sharing your build!

Most everything is here on this build thread. Is there anything specific you’re interested in seeing? Yep, it’s a T18 from a 1979 CJ (Found on Craigslist). Yeah, one of the challenges is finding intermediate specific parts where you need them. I upgraded some parts for that reason. The steering column was probably the biggest wall I ran into in that regard. The frame being narrow in the rear also made it challenging for B & C pillar tie-ins and longer shock mounts. The 1” body lift really helped. Let me know if you have specific questions.

Bad news for me. I think I have a parasitic draw somewhere, possibly related to the EFI. Had a slow start over the weekend, and a high idle issue that I thought I resolved. Tonight the Battery was stone cold dead. Jumped it and took it for a short drive. It would not idle below 1800 RPM, my guess in response somehow to the electrical issue, whatever it may be.

After the drive the battery was down to 7 volts. I Disconnected it and have it on the charger tonight. Will see tomorrow if it will hold a charge. If so, then next I will be hunting down some wires. Called my neighbor to help me trace things tomorrow with his better knowledge of circuits.

Always something right before a trip. Was planning to make a local run later this week, then another Moab run in two weeks. : Although more expensive, I’m kinda hoping it’s as simple as a bad battery.

Did you say that you took it for a drive and the battery was still down to 7 volts? Even if you have a draw some where the alternator should still be charging your battery up to full charge during a drive (depending on length of drive). So if that’s the case I’d check the alternator and related wires.
I check that you have a few good ground connections from your block to your chassis. Bad grounding can cause a few different and annoying issues.
