Because it costs absolutely nothing to do, and is the perfect first check.

The PTM modes have no affect on what gear the trans starts in.
With the shifter in D, it doesn't downshift from 2 to 1. M does.

It's actually 200rpm. 5800ish in D and 6000ish in M.

HIGHLY doubt it. It took a long damn time for anyone to crack the PCM and I'm betting the Hellcat's will be even more intricate. Then again, I haven't seen anything about what PCM it will use, so maybe not.
Still though....HIGHLY doubt it.
Also...hope you're wrong so that my 11.0 car isn't getting beat by a stock Hellcat on a tire.

Not really. The low octane timing map has about 10 degrees less timing in it than the high octane map. Pull 10 degrees of timing out of your GTR and then tell me if you still think the same way.

I've seen 3 or 4 ZL1's at the track I go to that the owners idled the car in the staging lanes and ran low 13's over and over and over. Heat soak city.

I think it's certainly possible.
Another forum member had his car dyno'd recently and bone stock he made 55 or 60 rwhp less than a normal A6 ZL1 made. And it was on the low octane map.

2ss-booya · 08-18-2014, 01:23 PM

my point was that there are in fact people that believe putting in 87 octane in a car that requires 91 or above is not a problem. I hear people all the time saying "oh well my car sounds just fine with 87"

JackalopeZL1 · 08-18-2014, 01:32 PM

I remember mine shifting 500 early.. I will have to check this weekend

I hope the OP gets his issue fixed, I really do. However, who here really thinks pulling a fuse is going to solve his problems? Really?

WTF is any of the garbag your posting helping. there are guys on hear running .5 seconds faster than your car with simple bolts on's and you talking smack.

talking smack about a 9.8 car when you run 11.3??? that is just retarded. 55k+20k in mods =75k car running 9.8's and you say that is pathetic. go run 9.8's for less that 75k then come back and talk.

telling someone to just sell a car is your solution???

You're comparing flywheel HP to rwhp. What you really need to do is hit the drag strip and get some "real" numbers. Bottom line is yes the ZL1 is slow if that's what you're trying to get at but you should be able to easily run mid to low 12's in the mid teens. It also takes very little to make the ZL1 a very fast car without having to upgrade a bunch of drive train parts along with it.

Pretty sure the fuse pull deal is a non-issue with the LSA but I also know others will swear by it so by all means give it a try.

One reason I like running the Palmer Performance DashLogic is I can see how much total timing the engine is getting when I go wide open. 23-23.5* is usually what I see. ZL1 is also a bad choice for a drag car since they are heavy as heck. I do love it for what it is though. Comfy for daily driving, pretty quick in a straight line, and can get with it on a twisty road.

^^^^ This... you need to know what your IAT2 is running, especially in the summer. I had a bone stock Challenger catching me on the road track when my fluid pump went out and IAT's went up. And this was at 670 rwhp. So yes this is an important number to be aware of.

CanadianZL1#992 · 08-18-2014, 01:51 PM

I am one of these guys that leave the car running, here's why. I monitor my iat2's with aero force gauges. If I make a run and get back into the staging lanes and push my car up the line (shut off)for 20 min by the time I run all that heat has migrated up into my supercharger.
When I start the car my temps are at 58 to 60Celcius. HOT enough to pull timing and doesn't have enough time to cool down before I make a pass. If I idle the car up my iat2's stay around 40 to 42Celcius when I pull up to do a burnout. Under no boost idling the pump is circulating the intercooler coolant and my engine fans are drawing air through my heat exchanger. I've data logged my car several times and it will pull timing if I shut it off in the staging lanes

JackalopeZL1 · 08-18-2014, 01:54 PM

My self too.. I pop the hood, let it cool between runs.. A little effort to keep them cool goes a long way

I open the hood also but let the car idle

If you have HP Tuners you can also turn the blower coolant pump on with just the key in the on position. Same for the engine cooling fans.

Maybe the car has a bad tune in it?
Maybe the previous owner had some mods and took them all off and didn't have the original tune back to stock? Maybe it's a tune thing? Either way, that should not happen at all.
Good luck going forward and keep us posted on your solution.

That's my next step and would be a better option than idling

Supaslw · 08-18-2014, 05:20 PM

Thanks for all the input, I will continue to do the little things like the fuse reset, and continue to put the higher octane fuel in it. Maybe I just need more time to play around with her.

I wasn't trying to bash you but maybe dyno to see if all your power is there because I do see people from time to time posting low dynos even on YouTube and I know it's not normal

OP. i am baffled too . logic would seem like your new ZL1 would outrun the older camaro. what is the HP rating on your 99 SS, like 320? if i recall, the base z28 then was like 305 and the SS ram air was 325, at least in the trans am. the 99 is lighter than your ZL1 too. also, what is the gearing comparisons too? but, i have to agree, you shouldnt have to do anything to the car for it to outrun the older car. just seems strange to me too.
