2000 Hotside AA/IC 115/65 pulley

[Scuba Steve]

Here are the maps from my runs yesteray. Overall I am still running a bit rich an have a lean spike from 6k to 7k.

Look at the maps and tell me what you think. I think on my next dyno trip I will reduce the green/yelllow/red settings and slightly increase the pc-pro to get rid of the spike.

Run 1 204HP 160TQ
Pcpro Settings
Green - 4
Yellow - 4
Red - 4
OVerall Cruve - 8
E-cool - 2


Run 2 206HP 166TQ
I leaned it out by reducing the overall curve, and increase the red setting to add fuel above 5500RPM. Notice it seemed to only work between 5.5k and 6k. I still had the spike above 6k
Pcpro Settings
Green - 4
Yellow - 4
Red - 5
OVerall Cruve - 7
E-cool - 2

Run 3 203HP 166TQ
I set the red setting back to 4 and increased the e-cool to try to reduce the spike above 5.5k. It seeme to help a bit
Pcpro Settings
Green - 4
Yellow - 4
Red - 4
OVerall Cruve - 7
E-cool - 3

Run 4 193HP 159TQ
I reduced the overall curve to run a bit leaner and increased the e-cool to help the eliminate the spike some more. I believe the HP loss is do to heatsoak. This was the 4th run and it was a 90 degree day
Pcpro Settings
Green - 4
Yellow - 4
Red - 4
OVerall Cruve - 6
E-cool - 3.5

Steve, the graphs are really hard to see. Can you link them as a pic instead?

[Scuba Steve]

I attempted to use links. Hope they work.

Steve,

The graphs were small for me but I saw the tail up towards the end. Is that what you mean? That looks like you are running short on fuel. I would love to know, next trip to the dyno, what the fuel pressure is doing at that point? Might want to add a couple clicks to the red zone. If that doesn't help, fuel pressure numbers are needed. Otherwise, what I could see of it, didn't look too bad.

That could explain it.

Do you have the OEM fuel pump or aftermarket?

What, if any, significant differences would it make if these same settings were made to a Coldside unit
