Ignition timing when at low RPM?

I've had my car tuned remotely via opensource by a popular tuner. It runs great. But I've always thought the car was sluggish off the line when letting out the clutch in first gear. It's like at 800-1500rpm you have to floor it when going up a little hill and letting out the clutch. I've looked at my tunes but have a hard time finding what load I'm at at that low of rpm but it looks like to me the timing is set really low at -2 to about 4 degrees.

It's has to be low when at WOT and 1000rpm but I thought that was a little too retarded. I was thinking more like 8 to 15 degrees but I don't like messing with timing.

My other cars that are tuned run like 8 to 15 degrees off idle when at WOT

What do you think? Thanks for the help

Depending on RPMs and throttle position my timing can vary from 16 to 50 degrees... and as low as 13 degrees at WOT past 5,000 RPM. The ONLY time I ever seen -1 degree was when I first start up the car for the first time that day... Not a tuner and these are just observations... :)

You should NEVER be at WOT @ 1,000 RPMs. not even 1st definitely not in any higher gear... JMO even at 2,000 RPMs in 3rd and higher it's not advisable... Again it's JMO If that's what you are doing than I can see why, the ECU is trying to save your engine...

A very reputable tuner. Well at WOT and 1000 rpm I know the timing will be low but I want to know what is normal
Take a screenshot of your base and advanced timing maps

Unless you can datalog,we can't help you. This is pretty fundamental stuff as far this stuff is concerned. Without certain data it's just blind guessing..........

I was driving around today in my '09 stage 1 STi and remember this thread and decided to try and see just what the WHP was at low RPMs, there was a bit too much traffic so I didn't do a "real' test, (these numbers are from 1 run and aren't necessarily that accurate as it's hard to get everything just right)... :wiggles:

1st; 1,000 RPMs.. 50 WHP
...... 2,000 RPMs 120 WHP
...... 3.000 RPMs 220 WHP

2nd; 1,000 RPMs.. 20 WHP
....... 2,000 RPMs 100 WHP
....... 3,000 RPMs 200 WHP

3rd; 1,000 RPMs.. 17 WHP
...... 2,000 RPMs. 75 WHP
...... 3,000 RPMs 175 WHP
