ok it's Deff not lean my wideband is under 11 at cruse and 14ish when acceling and lean out on decel.

Why would you want the air/fuel around 11s during cruise? And 14s during acceleration? Those numbers don't seem right.

remember i have those huge *** injectors cam/heads lower c/r ect and no turbo..... and a mail order tune

**Jerriko** · 03-06-2005, 03:12 AM

It should NOT matter how large the injectors are (or any of the other stuff for that matter). While accelerating, a/f ratio should be a lot lower than that and be consistant, not eradic. The same would also go for cruising except the a/f ratio should be a lot higher than 11s.

i mean not WOT just in traffic... i though it was weird too.... it could be the exuast leak at the EGR making it all funky

ok like if im in 4th gear goign like 35 the AF is like in the 10's, if i give it gas the Af rise's to say ~12's and if i give it lots of gas it goes to ~14.5.... if i just let off the gas it goe to like ~17's ......

Where did you get that tune?

A few points about that tune:

1. Your VE table has 80 in every cell. That is certainly not right.
2. Your high Octane table and Low Octane tables are basically identical. Unless you are running MAFless, that is not right.
3. Your Injector Flow Rates are flat across the chart, they should be lower at 0KPA and about 3# higher at 100 KPA, again, not right.
4.Your fuel cut-offs are set at 7200 rpms, if your motor can handle that, great. However, your spark is limited at 5900 rpms. Once you hit 5900 rmps, the max spark advance you will get is 15*, robbing all your power.
5.P0300 DTC not disabled. That is why you are detecting missfires. This code should be disabled if you are using an aggressive cam.

I have looked at lots of tunes and I must admit that is the most messed up one I have ever seen. GET YOUR MONEY BACK. Go back to your stock tune and do the following:

1. Your injectors are the biggest concern. I assume they are 60#. If so set the 0 KPA to 60 and scall up to #63 at 100 KPA.
2. Diasable P0300.
3. Make your Low Octane Table 4* less then your high Octane table in every cell.
4. Raise the Spark Limiter to 200 below your redline. Set your fuel cut-offs 100 below your redline.
5. Your stock VE table will be fine for now but you will need to adjust it eventually. Go to HPTuners.com and go to the V8 Engine tuning forum and read about how to do it. The V6 is a little different but when you are ready to tackle that, either e-mail me or post up, I can help.
6. You should be able to advance your timing quite a bit with your setup. Try 3* accross the board and see if yu get more knock retard. Again, go to HPTuners.com and I did a thread in the V6 Engine forum on how to set your advance.

Final issue. Do you see a lot of Knock Retard? Most agressive cams will give you false knock. One last time, go to HPTuners.com and search Knock Retard in the V6 forum, lots of info there.

Good Luck!

westers did it over the mail order tune
A few points about that tune:

1. Your VE table has 80 in every cell. That is certainly not right.

acuualy if you at any stock 1997 M5 camaro thats how it is... i have seen 3 bin files like that !!!

2. Your high Octane table and Low Octane tables are basically identical. Unless you are running MAFless, that is not right..

i didn't mess with those thats all westers...... they probly just pulled timeing from the high octane side

3. Your Injector Flow Rates are flat across the chart, they should be lower at 0KPA and about 3# higher at 100 KPA, again, not right..

again this is how they are stock for this year, i did adjust to try to lean out the idle some i have 57# hour injectors..... so in this table a larger number = more fuel or less fuel?

4.Your fuel cut-offs are set at 7200 rpms, if your motor can handle that, great. However, your spark is limited at 5900 rpms. Once you hit 5900 rmps, the max spark advance you will get is 15*, robbing all your power..

yeah the motor can handle 7200, right now every thing is set at 6400 where the stock tabel cuts off

5.P0300 DTC not disabled. That is why you are detecting missfires. This code should be disabled if you are using an aggressive cam..

thats the thing.... its not throwing a code i just see misfires on the scanner

I have looked at lots of tunes and I must admit that is the most messed up one I have ever seen. GET YOUR MONEY BACK. Go back to your stock tune and do the following:

yeah cant its been to long since they did the tune

1. Your injectors are the biggest concern. I assume they are 60#. If so set the 0 KPA to 60 and scall up to #63 at 100 KPA.

does scaling up add more fuel at the top end or less?

2. Diasable P0300.

it not throwing it yet...... lol

3. Make your Low Octane Table 4* less then your high Octane table in every cell.

will do

4. Raise the Spark Limiter to 200 below your redline. Set your fuel cut-offs 100 below your redline.

thats how they are now

5. Your stock VE table will be fine for now but you will need to adjust it eventually. Go to HPTuners.com and go to the V8 Engine tuning forum and read about how to do it. The V6 is a little different but when you are ready to tackle that, either e-mail me or post up, I can help.

yah the table is confusing to me i really don't understand what the hell it does as far as tuning

6. You should be able to advance your timing quite a bit with your setup. Try 3* accross the board and see if yu get more knock retard. Again, go to HPTuners.com and I did a thread in the V6 Engine forum on how to set your advance.

yeah but i can't test this till my turbo is on and i can see how it's going to react to lower C/r

Final issue. Do you see a lot of Knock Retard? Most agressive cams will give you false knock. One last time, go to HPTuners.com and search Knock Retard in the V6 forum, lots of info there.

Good Luck!

no i do not get ANY AT ALL all the way up to 6400... and even 7200 the one time i tried.....

thanks for your help

i made some changes

what you think?

**arthansen** · 03-06-2005, 05:52 PM

That looks a lot better.

Something else is weird, in your PE tables, your PCM is calling for 7.2 AFR at 6000+ rpms. Look in engine,Fuel Control, Power Inrichment. These are the tables that control WOT. If you look in V6 Base vs ECT, you are calling for 11.8 at normal operating temperature. Now look at Add vs RPM. In the 6400 column (which controls 6000+), you are calling for -4.6. You add 11.8 and -4.6 you get 7.2. Don't adjust that yet, however, because even though it is calling for 7.2, you are showing 14+ so leave that for now.

The flow rate table can be a little confusing. By raising the numbers, you are telling the PCM that your injectors are putting out more fuel so the PCM askes for less. Thus raising the number will give you less fuel or cause you to go more lean (hope that makes sence).

The most alarming thing is that at cruise you are not at 14.7. That means the car is not functioning in Closed Loop. Do a log using the default PIDs so I can see your O2s and Injector Pulse Widths. Add one more PID, it is called "Fuel System Status (SAE)". It will tell us if the car is in open loop. If you have to delete a PID to fit it, take off ECT but make sure the car is at temp before you log. Also, if you can log your WBO2 that would help.

Even though the AFR is going up in WOT, that might be because you car is in Open loop and using that strange VE table. We will address that next. Do a log and post that up and lets see where we are.

there are to logs i have the day i got the software just messing a round i didn't do any driving on them just some revs.. i get the other you wanted tonight or tomarrow

**arthansen** · 03-06-2005, 07:23 PM

Take out the PID for Dynamic Cylinder Air, it does not work in our cars and actually causes some problems (not with a tune, just logging). That is why your histogram for spark and KR are not working.

I need to see one from driving. Just post up and we will figure this out.

**Turbo V6 Camaro** · 03-22-2005, 07:44 PM

still waiting on my block off plate then i will get theese log i want to fix the exuast leak frist and make sure it not thorwing off the WBO2

**Turbo V6 Camaro** · 03-22-2005, 07:55 PM

alo on the sprak advance table high spark thershold: i set to 6500, ok thats the spark limiter mean the motor can't go past 6500? or is just use the vuale under it and thats the timing you get?

high RPM spark is the timing it give the motor above that amount right???

EX: if it was 5000 above 5000 the if the hight sprak was set at 10 it would only give a max of 10* advance right?

**arthansen** · 03-23-2005, 09:03 PM

Correct!

On the sprak advance table high spark thershold, this is what your max spark can be above that RPM. It is designed to take away power at higher RPMs. 6500 should be fine. You will be able to go over 6500, but the timing will only be what you set in the box below it (I have mine set at 6400 and 10*). So above 6400 rpms, my timing will never be more then 10* advanced.
