Content with kPa, or is it not a selectable option?

Not exactly sure at the moment. Still a little foggy last night.

I'll just post these up.

Super confusing! Is your boost gage in kPa as well? Lol. And is that absolute or gage pressure?

 

kPa as it's used in that table is an absolute pressure scale. Roughly speaking 101 kPa is 14.7 psi or what you typically see as 0 on your boost gauge. 30 in-hg is the same as 14.7 psi of vacuum, so 0 on the table is max vacuum. If your table is in-hg/PSI, take the kPa value convert it to PSI and subtract 14.7 to figure out where it lines up with your table.

 

It's not too difficult. Like @buyobuyo said, vac is under 100kPa and boost is above. It's like using metric vs standard. Here's a conversion:
kPa Vac/Boost
0 29.5
5 28.1
10 26.6
15 25.1
20 23.6
25 22.1
30 20.7
35 19.2
40 17.7
45 16.2
50 14.8
55 13.3
60 11.8
65 10.3
70 8.9
75 7.4
80 5.9
85 4.4
90 3.0
95 1.5
100 0.0
105 0.7
110 1.5
115 2.2
120 2.9
125 3.6
130 4.4
135 5.1
140 5.8
145 6.5

210 16.0
215 16.7
220 17.4
225 18.1
230 18.9

I think I'm gonna scrap my turbo build and just build a big ramp, looks like acceleration will be pretty quick

 

You're just proving my point. I was mostly kidding but thanks for the attempt at clarification.

@boostedka What do the numbers in the cells represent? Are those the stock pulse widths? And why did you choose such a high upper bracket? Unless your software can interpolate you're going to be leaving a lot of precision on the table.

 

That was fawking awesome!!!

 

The landing will definately need to be adressed but i see no other issues

 

Totally bailed on the landing. Have you guys not seen Travis Pastrana doing a backflip on a big wheels trike over a 100 ft gap or something ridiculous?

 

NITRO CIRCUS !!!!!

 

This way it gives me room to up the boost later on as much as the truck grows (like building the motor in a few years) and already have a decent fuel table in place. I could get more exact with my current boost levels by lowering the top end amount of boost and be able to tune every 0.5psi, but the practical difference it would make in my AFR's wouldn't be insignificant.

 

@boostedka did you ever have any problems with going lean intermittently part throttle around 3 psi boost when you were running pink tops and stock Ecu

 

I had that problem before my piggyback. Closed loop is fighting you.

 

It’s hard to let go because it wasn’t doing it before I messed up the O2 sensor with leaded racing fuel it was running good I didn’t have any leaning out or hesitation it’s too bad there isn’t a piggyback for less than $200

 

I know that using water/meth is not a substitute for fuel but since ur not at the end of ur injectors abilities, could this eliviate some of the issue. Just have it set to start spraying at 1 psi and get progressively more open as boost goes up? I feel like u can get a kit for $200 and im not sure it would fix the closed loop lean 100% and you would also use alot and need to keep an eye on it. But i do feel like this route will leave u wanting something else and in the end be $200 you would have spent on a piggy back

Thissssssss

 

Not even. I didnt have any issues with it running lean at any point. It was basically high 14's until the stock ecu arbitrarily decided to dump more fuel. It pretty much ran like stock til it boosted

 

That’s what I was thinking. I still can’t let go of the possibility that I could have an issue with something any ideas it was running like stock until I messed up the o2 sensor I’m thinking I need to make sure there isn’t a fuel pressure drop when this happens
