Stand alone ECUs are far more configurable, for those that like that kind of thing.     Better engine safety strategies as well.

Welcome to the site!   Most of us arenít really anti-rotary, there are several owners that have rotary and V8 cars.   :)

Iíve gone all nylon on everything for a while now.   Looks nicer and pokes me a little less.    I do have some stainless outer braid stuff in a few places because I had inventory or because it had better heat resistance.

Here's a measurement of my hoses.    The first is a "typical" 8 AN that has already had a connector screwed into it before (thus is slightly enlarged) and the other is a fresh piece of the PTFE "8 AN":

Difference is 0.4mm or 0.016" which is about 3.5% smaller.    I'm not overly worried about that differential for my uses, particularly because probably 50% of it was the rubber hose "taking a set" to the fitting that was in it before.

Interesting, the lines I have are only very fractionally smaller than the rubber hoses, from an ID perspective and roughly the same size as the fittings.   They can't be more than 3-4% smaller at the very most, and are definitely much smoother internally.   I'll check them with calipers, but the fittings that fit snug into the ID of the PTFE hoses fit snug into the old rubber hoses, so they're pretty close.

This ^^^

Syvecs was on my short list for new ECUs, but looked like a bitch to tune and they were $$$.

So, the last thing that's hooked up and not working is my transmission speed sensor.    I pulled it today and validated I do NOT have continuity to the ECU.   I know that the new harness is good, and it also did not work with the AEM, so I either have a bad crimp on the connector near the VSS, or, more likely, the pin is pushed loose in the connector where the tranny goes to the main harness.  I did NOT rebuild that sub harness when I redid the rest of it, so I'm sure that is what was wrong.    It's not super fun to get to though as I have to pull the intake, which means pulling the harness, fuel rails, fuel lines, and strut brace, which is like a 45 minute job.    I'll do it soon.   I have my GPS speed, so it's really just ECU input for cruise control (not hooked up) and traction control (not hooked up since I don't have a front VSS yet) that it matters for.

I've been driving it around working on the tuning.  I've got the cam VVT working properly and looking reasonable, and the alternator is charging properly now.   I have almost got the little lean shudders out during light load acceleration and my actual wideband results are getting pretty close to the commanded (and I put in a sane commanded table).    I've rolled it into a little bit of boost a couple times and it's feeling good.   I've only blipped it up to 3-4 psi so far, but it's doing well so far and the fueling is fairly close (close enough I'm not going to hurt anything).   Going to give it a couple hundred more miles of tuning then I'll roll it over to E85 and adjust the flex tables to keep fueling in line.   I want to get 93 octane dialed in nicely first so that I know that any differential on E85 is just the fueling and I'll be able to adjust the flex transition tables or 4D fueling tables to dial it in without jacking up my main table.    I want to be sure it can stay on either fuel easily so that I can store it with gasoline or put gasoline in if I can't find ethanol while out and about in the future.

All in all everything seems happy.  I had forgotten how slow the steering was, I need to swap to a faster rack still and I'll need to deal with my fuel pump situation soon.   If I keep it under 10 psi the single pump will probably be fine, but I'd like to go ahead with the brushless Deatschwerks pump sooner than later, and maybe some Radium fuel rails with a pulsation damper.

Oh, I had a leaky fuel line I found also, so I swapped that to a PTFE line.   Going to buy some fittings and start getting the rest of the lines converted over to PTFE as well, so that when I do go E85 I don't have to worry about the rubber.   The PTFE ones are nicer to make and a little smaller externally, too, so it's all wins.

I had a Dakota Digital VSS on my Glide

The fender/door things do a little, if the benefit is worth the weight is probably debatable.   A cage does the most.

You're right, that was a glitch.   Fixed in the original post.    Glad you found it useful!

Sorry to resurrect such an old post, but I'd like to change me Screen name to "Franken-7" please

Send me a PM and I can help.

If you gear it right, it should be fine.   I considered one with a high rear gear to use the 1:1 like an OD and the other 2 more like a Glide.

Yes.   Actually the Haltech wires up basically identically to the stock LS1 PCM.    You can replicate the OEM wiring from the first post and set your Haltech IO appropriately.   I have a simplified version of this layout with my Elite 2500.
