Also, when it says to torque down the top caps, does it mean the hex screws that are part of the SAE posts or the ones I circled in the picture?

I didn't have posts on my battery. But it looks like the screws are for the posts.

You will need at least one of the screws for the negative cable. It wraps around to the left to provide another post for the car's negative clamp. the positive terminal may or may not require the bolt to hold down the various connectors. Bottom line, the connectors have to reach, and they have to stay tight.

I used the smaller screwsthat came with the odyssey for the negative. I feel like I don't need the bigger screw that came with the SAE post to go on top of the positive since I don't need to screw on an eyelet connector to it?

Looks good

I ended up putting the top screw on anyway since it looked kind of bare without it. Finally retired the powersonic!

This week I've been working on a tweak @steve99 passed on, the Tip-In enrichment tweak. I tried it his way and it shifted much smoother, but had a bit less power, so I figured it wasn't right for the ESC and I could do better. Well, several tries later I can show you how to do it worse in many ways, and 2 ways to do it better. Once I had the Tip-In figured out, I started working on Port Injection to try and get better cruising mileage, my theory being that Port injection gives worse mileage. It's easy to tune for more power, or more mileage, but tricky to tune for both. Here are some pics of my changes compared to the same tables in an OTS ESC tune. The Cold Port Injection map is unchanged, while the Warm and Hot maps are changed the same way. When I have time I'll start adding these to the other tunes I have made, and make them available.

Here are the same Ultimate tunes as before, but now they have the Tip-In and Port Injection tweaks. I think the Port Injection tweak has stopped the tune from leaning out between 2000 - 3000 rpms, but I haven't logged it yet to find out. The AT tunes are in the 91 AVCS Tip-In Port Inj ATs zipped folder, and the MTs are in the 91 AVCS Tip-In Port Inj MTs zipped folder. You will need to unzip them before you load one. They are all 91 Octane so they should work with any fuel, no matter how crappy. I got a 29.8 MPG average today, and I started the day at 27.6. I wasn't trying to economize either, I stomped it to get around a slow Prius on the on-ramp and had to hang on. It was up to 80 so quickly! This will get over 30 MPG on the highway and even as a combined city/highway average, but who would want to? For those AT drivers out there, just put it into D and go. It's responsive enough that it's even fun to drive in D, (Automatic shifting mode). It takes a little getting used to, but you can pick how many gears it downshifts by how hard and fast you tap the throttle.

Friendly PSA for Procede users: Vampire taps are garbage! Solder or crimp your connections at the ECU harness if at all possible. Just spent most of the day today replacing those taps because my Procede decided it would be cool to go full throttle after a bump on the freeway.

Doesn't the procede get its input from throttle position and rpm? Don't see how it would go full throttle unless you close the circuit from the previous WOT switch wire.

I'm not sure exactly how the Procede interprets the voltage from its inputs. What I do know is when I hooked up my laptop and jiggled the tapped wires as my first troubleshooting step, the throttle input jumped around all over the place and I actually heard the engine throttle blade engaging (key on, engine off). Took that tap apart and the ECU harness wire broke. Would've been real shitty if that had broken completely out on the road.

You make it sound like it should only be used while driving in D and not in the manual transmission mode. Is this true or am I just reading this wrong?

AT's are a whole other driving experience. The trans controller hasn't been cracked yet, so we AT owners have to tune to the trans wishes. It shifts when it wants to. A common issue is bogging after each shift, since they are geared much higher and have no way to slip the clutch to gain more power. Another common issue is rubber-band shifts in manual mode. I've recently learned this is caused by the ecu's delayed reaction to the change in rpm's. It is completely solved by using the correct ratio of port injection to direct injection. I'll be coming out with a whole new set of tunes that are way better for AT's then the ultimate tunes. I'm just finding the limits of adjustment now and fine-tuning for AT and MT's, since the tuning isn't the same for both any more.

Ok because I'm extremely interested in this kit but I drive in Manual mode 99% of the time, and I don't think I could give that up even for the 25whp and the torque increase.

I used to do that too. It was the only way to keep from being annoyed at the lack of power. Now I drive in manual mode anytime there isn't any traffic, and auto mode in congestion. What's your CAL ID? I'll post you a preview of the new tune. You'll be surprised how much more fun auto mode can be.
