Catmaigne's "LolT1" Budget Boost Buildup

I saw that, but I think it only pertains to the Termi X Max. The regular Termi X doesn't have a J4 connector or any of the trans ICF stuff AFAIK.

Ohhh, sorry, didn't know you had a non X max.

Edit, you should be able to feed two wire VSS straight into one of the inputs of the termy x

Well.... it runs. Haven't driven it yet and everything is filthy. Tomorrow I will throw the wheels on and see how well it moves. Everything is pretty much buttoned up except for the rat's nest of wires in the passenger footwell.

It looks very sanitary, nice work. How bout a running video?

I'll try to get one soon. I also have a 2step programmed to one of the inputs so I can annoy the neighborhood.

Looks good!

Did you just do the holley game boy tune setup?

Yeah I've been running on the supercharged 24x LS base calibration. Only tweaks I've made are for my I/Os, sensor data, and firing order. Drives suprisingly well, but this lazy LS timing table needs to be dialed up, especially off idle.

I know on the base tune my holley spit out, it worked great for idling and part throttle but the generated timing curve was piston meltingly bad.

Generated as in a base cal table, or something else? Still getting familiar with this software. I think my table should look like a rescaled version of this.

I think I could add 5 deg across the board in the idle and cruise areas, but I need to take a closer look at it. Looks very lazy for gen 1/2 architecture. The SBC base cal uses the same table strangely.

Here's a timing table from a really old rev of my 2bar SD tune on the stock pcm. Hard to read because the axes are flipped and the MAP is scaled. Atmospheric pressure was about 55kpa after scaling and the car would idle around 30kpa after scaling (50-55kpa irl). I'll have to dump all the info into an excel to better view the differences. bin25timing.jpg

I did two quick and dirty comparisons of my current Holley timing map (the base cal) vs. a NA Solomon tune I paid for and my own stock pcm 2bar SD mess with the rescaling undone. They look like this:

This is only in vacuum, no racecar stuff yet. Some thoughts...
- Thing is reaaaaally down on timing with the stock LS cal. Probably why it feels like a slug off idle and with low throttle.
- My 2bar SD tune ran out of resolution starting at 40kPa and below which is why all of the numbers are the same down there and the peak is around 50kpa.
- My 2bar SD tune is considerably softer in vacuum than Solomon's as I've always thought his stuff was too aggressive. My IATs were never too far off of ambient in vac and the drag of a blower venting to atmosphere isn't a crazy amount. Don't think an NA tune would be worlds apart under atmospheric pressure.
- I unfortunately have to assume that the indexing of the EFI 24x wheel is on the money with the Opti, which it probably isn't. There's probably a few degrees of fudge in there.

Gonna dial it up a bit and see how it goes. I also need to play with the EOIT stuff, but we'll get there.
