Thank you sir. I have not read those yet. I will do so!
Although I seldom log on to the cobalt site, I've seen you there.
I suppose I should tune my LSJ too.....

Top Sportsman eh? That's a fast...

LNF yes

That car ran well. Sadly the owner passed away about a month after we finished the tuning.

I really want to know about tuning this GXP

Thanks

Hey folks,

I've been tuning for 7 years now.
LS NA, Turbo and Supercharged.
Dodge NA, Turbo and Supercharged.

I've tuned exactly one Ecotec, a turbo swapped 2.4L Solstice.
Came out nice...

Gap them at .016-.020? and see it it helps.

I can't open your file. Says unsupported or newer version detected.
I'm running the latest HPT version 4.2.12

Been through trying to tune the LS3 480/495 with the idle etc etc.
First thing the...

Godspeed Ed!

Cool info. I?ll try this on the LS3/480 I worked on this month after the customer moves his air intake to a cooler air location.
Ron

Thanks DHC. That was actually the first solution I thought of. It's a 4x4 so there is plenty of room. The owner built the truck, and he can fabricate.
Should move the MAF too. The alum intake tube...

Thank you! I had suspected as much. Now I can quit spinning my wheels and get to fixing the myriad of other issues on this install.

Like the MAF too close to a bend, and the air filter tucked...

I am trying to understand why this setup won?t idle where I tell it to. If I tell it 700, it should go there, it won?t. I?ve tuned a few of these MAF only, one a turbo 2010 Camaro, and they follow...

Thanks Greg!

Seems I?m tuning engine swaps lately.
This LS3 is in a 59 Apache panel truck.
Auto trans with a stall and separate controller.

Car was dyno tuned by another shop, so I don?t have the orig tune...

Typo. P1516
I did the throttle test you suggested. Set up a layout screen just for the 5 throttle functions. I can see where the tps gets ahead of the pedal. It actually set the code during that...

Thanks for the suggestions. I did check the TB connection. It looked clean, but I gave it a shot of contact cleaner anyway.
I also physically moved the blade with my fingers. It feels notchy with...

I'm tuning this Solstice with an L77 from a Caprice.
The Solstice swap guys wrote a program for an E67. I've been fixing pretty much everything.
The engine is stone stock, so I've been referring to...

So far I?m just tuning the MAF. Has a card style MAF instead of the round one that came with the engine. The MAF cal in the provided tune wasn?t close at all.
I put it in MAF only, turned the VVT...

I have one at our shop as well. No doubt the same company...?.
Ours has a 2011 Caprice 6.0 and the 6L80 auto.
Same story, ECU is locked, and the car was undriveable. The engine is stock.

The...

Hey folks
2010 Camaro SS Auto

Car was previously tuned by someone else. So I don't have the orig tune file.
But I'm not seeing any changes in the throttle tables from stock.

If you look at my...

I think I get it now. After re-reading the other thread.
I told the ecu to make more pressure. It responded.
Did another pull, same result.

When you are out of pump, you are out of pump.
Given...

Ok guys, thanks for all the help.

I modified the FPCM with the ZL1 parameters.
I didn't mess with the Fuel Pump Duty Cycle portion.

I did tell it max boost would be 225 kpa


I saved it,...

When I open this file with 4.0X it's simply blank. Everything is blank...….even though it appears to open
Any ideas?

Nevermind…...

Thank you. I?ll print this stuff out and sit down with it on Thursday. Boss needs the laptop and cable for another project tomorrow.

Ron

Ok folks, I re-read the car with the latest 4.X version of hpt.

It seems to have read the FSCM.
There were no hpt warnings etc.

Haven?t tried to modify it to see if it will save.

The link...

Hey, thanks! I had no clue. I?ll investigate!
