I'm still learning how the scanner works lol.

[QUOTE/]Remember we are only scaling from 7000hz up in the maf table like so.

Now we do not want any spikes in the maf table so in the cells before 7000hz scale them so they will flow with the rest of the table..[/QUOTE]

A little confused to as what he means by scale them before 7k...am I "smoothing" the entire table? Smoothing just before 7k? When he means scale them i assume that's what he means. Right?

I'll just assume once I've done over 7k I'll smooth the entire table.

When I do long runs for getting LTFT and MAF data I only ever go to 7,000hz when I enter the new data.

I only ever adjust the MAF above 7,000 when I have to add or take away fuel.

I'm assuming 7000 hz is the point where you hit power enrichment? I don't think it would be the same for the 04+ guys though with different mafs and other variables as compared to the 97-03?

Yeah i have never adjusted the 7k+ yet. I also would have to do it with the narrow band since I don't have a wideband yet. I think I might wait until I get one before I start adjusting that.

You can still knock out your maf tune though with stft vs mass air flow. As long as you get your stft dialed in your ltft should be in line as well.

Totally need someone to just do this for me. Got alot done but just feel like I'm not doing something right

I've been having trouble configuring my MAF LTFT table in the histogram. I've followed the write up directions twice, but I haven't even gotten a table in the histogram. The only difference I can see between the write up and my set up is the value in the units selection. It's supposed to be %, but the selection for that option is blank. Is that my prob, or am I missing something?

In that pic I am running very rich, I would need to pull some fueling by scaling the maf table in the editor. Small changes are the best. 2% at a time are ok if you are very far off like I am.

To add fuel you will need to add to the table by multiplying by 1.02, if you need to pull fuel you need to multiply by -1.02. Remember we are only scaling from 7000hz up in the maf table like so.

I believe you would want to multiply by .98 to reduce fueling not a negative number...

Perhaps when this was made, you could do that with whatever version of HPT was out. Likely 2.22 or 2.23.

Now with 2.24 and the beta 2.25, just doing .98 is the only way to reduce the number.

I dont think so. If you multiply a positive number with a negative number, you will get a negative number. Regardless of the HPT version number. The proper way is the multiply by less than 1 to reduce and more than 1 to add.

Infomation on HP Tuners forums is there, you just have to search for it. Or look for similar related things to find answers.

There are just too many people that don't have a damn clue what they just bought into and want to be spooned everything. The other problem is that too many people try to tune a modded vehicle as the first thing they learn with, they just make it 5x harder on themselves. I learned how to use it with a stock grand prix, then I modded it. Again with a stock GEN 3 LS V8 with my 2006 Sierra and again with my 2010 and now 2012 Silveado's for the GEN 4 computers. It makes everything so much better when the vehicle is stock and you see how everything works when stock.

I am still learning new things all the time and whats help me is knowing how the basics work. I have never done a speed density turbo setup on a LS V8 before but with all the time spent reading and using HPT on my personal stuff I know a great amount without having done it. I know the all the basic and even help others because I know what the tables are saying and the ways to change them.

The biggest things I say are to read, buy books to help understand how certain things mean and do. Then if that is not enough they have online training courses and the tuning school that people can attend. Sure it's alot more money but the knowledge you can gain from it is well worth the cost to most people.
