I loaded up the new 6MT 1-22 stage 4+ map and dropped the ign. correction down a bit (75%). As you can see it's definitely a bit too aggressive for my car on pump gas (boost isn't perfectly stable at the start of the pull and there is a little timing drop), but it definitely hauls ass. I did a bunch of pulls with my best time being 3.95 seconds 60-100mph (the rest were all around 4.05s). I'm going to run stage 3+ from now on, but I was just curious how this did on pump.

This is on shell 93 octane.

One thing to remember, my car is an XI with a big ole ski rack on top.. not the most ideal setup.

No meth just 93??

just 93, i'm not getting meth until spring/summer

My foot lifted to shift at 6462 rpm, at which point boost was at 15.1psi. Max boost in the mid-range was around 16.7psi

But like I said this is a bit too aggressive for pump gas (as can be seen), I just decided to give it a whirl since it's pretty cool over here.

^ thanks

Thanks for that JP.

I'm wondering if it would have looked much better with ign cor set @ 100%.

On 3+, what are you finding your optimum ign cor settings are before it pulls timing? I am going to datalog this weekend, but was hoping for some feedback from somone else running 93. I'd imagine once summer rolls in, you'd then have to relax the settings a bit too?

[jpsimon]

I don't have an optimal timing setting yet as I haven't tried stage 3/3+ with the 6MT maps yet. I'm going to load it up tomorrow and use that as my daily. I'll post up some stage 3+ 6MT logs maybe by tomorrow night

So this isn't using the Vbox then?
I thought you were using the Vbox for the times.

What about the slope (grade) of the road? Do you know that?

As long as you picked a flat stretch of road, the procede logs are extremely accurate. 30-35 samples a second. And the biggest source of error is wheelspin and tire distortion. But this isn't going to be an issue on street tires running normal tire pressures in 3rd gear and up. The only other potential error is going to be dependent on well the roadspeed readings is calculated. While the settings are accurate for my car (as confirmed with a Stalker radar gun), it may not be accurate in all cars due to rolling diameter variances amount tire size/brand/thread depth/etc,. But unless the diameter is way off, the numbers are going to be pretty accurate. And more than accurate if one just plans to look at the effects of tuning changes on their car. Consider it a tuning aid more than a bragging right. But then again, the same can apply to Vbox, Gtech, road dyno software, etc,.

No, never said I had a v-box (want to send me yours for some testing ? I'd love to compare a procede log to a vbox log). I probably won't be getting a vbox until summer

In terms of slope, it's as flat as it comes along my mexican datalogging route. This is the same stretch I used for my logs previously on less aggressive maps (where I did it in 4.1-4.3x).

Thanks for sharing....I guess anything other than race gas or methanol, most should not run map 4 or 4+, to be on the safe side!!!

[jpsimon]

correct-o-mundo. I'm sticking to stage 3+, even in these cooler conditions!

No offense to anyone, but posting an OBDII log time is less reliable than an iPhone time. Both are much less reliable than a GTECH. VBOX runs with the file available to verify slope is the only accurate way to measure 60-130mph, 0-100mph, etc.

[jpsimon]

send me a vbox and I'll redo it but for me this works in terms of "tuning", it showed my time improved over the previous less aggressive maps.

No offense taken. The PROcede samples wheel speed and time 30 times a second. All one has to do is find a flat stretch of road. If one is capable of that, it is perfectly accurate and very repeatable. It's not rocket science. Honestly Mike, if the JB3 logging didn't sample at 5 times a second and could read wheel speed, you wouldn't suggest using it?

When you say your timing dropped, what did it drop down to that indicates it's too much and that you need a lower (stg 3)..I'm trying to understand where timing is supposed to be under WOT

[jpsimon]

At right around ~3.6s there is a drop. When I run maps meant for pump gas that doesn't happen - the whole curve is smooth.

[ridin135]

how were the logs at stage 4 with 100% ignition correction on pump gas

[jpsimon]

I only tried stage 4+, weather was an issue

[dzenno]

I see the drop..but what value are you looking to see as minimum or right value in this case?

[Vince@ V K Motorwerks]

Why are you guys using the 60-100mph instead of 60-130mph which can be compaired with many other cars?
