Got dyno'd, take a look.

[nmcqueen469]

Went to a local dyno day this past weekend. The car made 394/349 on a dynojet. I was pretty rich for the majority of the run, in the 11.9-12.0 range. Moved closer to 12.5 up top. All of these were according to their WB. I have my LC-1 hooked up, but waiting for my HPT Pro cable to show up to start using it.

I'll post up a copy of the dyno sheet tomorrow. Please take a look at my tune and a log of the dyno runs and let me know what changes I need to make.

I definitely expected quite a bit more power and torque out of this winter's mods, which included ported and milled 243s, a ported FAST 90, a PTM 92 TB, Ford green top injectors, and 3.91 gears.

What's the inlet restriction? Should have dyno'd it without the elbow to see what you'd get.

92 kPa at WOT is really low, why only 18* of timing?

I would imagine it's the stock 78MM MAF now.

I've been fighting some hanging idle issues, which I thought was a vacuum leak, but I've searched high and low and can't find one. Some timing was pulled during the runs due to high IATs.

I haven't really touched the timing table, I've been focusing on the VE and MAF tables up to this point. This dyno day was kind of a spur of the moment deal.

Anyone else have any input?

Make sure you are getting 100% TPS when you step on the gas. You can do it with HPT sitting with the car off once the cable arrives.

I'm pretty sure I am, can't look at the log on this computer though.

Besides what the guys said above about rich at WOT and timing, it looks like you are having some timing (2 degrees or so) being removed at 5K/.87 cyl air in your scan. IAT timing may be attributing to 1 degree (102 degrees F) but not sure who is pulling timing. When you get your cable, log the timing family and make sure all is under control before tweaking the High Octane table.

The power will come when you get the Air Fuel and timing in line It is a nice flat torque curve.

Thanks for your response Ed. Which PIDs should I log for timing? Main advance? Knock retard? Others???

Here is the one I use

don't the 391 gears mess up the actually hp readings? I'm pretty sure they do. You won't read hp as much as you have due to them, iirc.

Thank you. I'll try that one out later tonight.

They do, but how much seems to still be debated. I read about 10% lower than I expected, so the gears could have some effect I suppose.
