I want a tutorial on Ford tuning

[Mep_q8]

Since there are so many releases on GMs front, why doesn't anyone release something for HPTuners on Fords?? We have plenty of Fords where I'm at but only one true custom tuner of 'em... I've played with 4 Fords to date, and bolt ons are a breeze to tune.. But anything more is a nightmare!!

When HP Tuners adds in the missing stuff, more Ford tuners will use it and you may see more information posted on it.

[Mep_q8]

what exactly is the missing stuff?? When it comes down to it, basics of tuning are fueling, spark and drivability... there seems to be the most of that.. I "de-tuned" a stang the other day, they removed the supercharger but kept the injectors, cam and 5.0 liter stroker on and managed to dial the MAF transfer in smoothly...

got my head around the same idea as setting PE then adjusting MAF to suit, although there is no AFR% error histogram...... idle airflow values, spark and the motor doesn't stall anymore.. the more i use HPT's on Fords the more I understand it, but would like more!

From my understanding the things James wants added that are necessary are:
1. Stoich AFR
2. FPVT (fuel pump voltage table) Axis (X & Y) limitation correction, some of the axis only goes to 4 units but is supposed to go to 8 I believe?
3. Breakpoint Multiplier vs. Pressure injector table
4. Spark Correction Lamba Spark for Base MBT

I'm still trying to get in contact with him to find out what order of importance he would put on these so we can prioritize them correctly.

Also according to one of our other customers the Max scheduled tq table

We have all of these on our to do list as we need to try and find these tables.

Give me unlimited GM credits and I'll gladly provide you with the addresses

I would like to see:

Ford speed density
Ford A6 support
More PIDS for idle tuning

[Bill@HPTuners]

I've updated my post.

In regards to your requests Grant I doubt we'll seriously look into adding SD tables for fords anytime soon.

A6 support is something we are looking into but is still a ways off think 2010 & beyond off.

No idea about the idle pid's again a ways off if anything.

4. Spark Correction Lambda Spark for Base MBT

5. Fuel Base vs. RPM vs. TPS%. The TPS axis Xref. I think it is just the Cell # that is messed up. (Change the Cell # value by 1, Then try to go back, The look at the TPS value in the table)

No worries

I think I can get by with the existing SD support anyhow - just takes a while to get your head around its predictive MAP model

I now believe pseudo-MAP based fuel trimming is there

Bill, definitely on the Max Scheduled Torque table, since that's important for proper ETC control.

Now, as for importance of those above, honestly all of them are just as important, but if I absolutely had to list them in a specific order, then you have it perfectly, save for potentially swapping #1 and #2 around.

I can't stress how important #2 above is for forced induction vehicles, since it's maxed out so quickly/easily on anything really above 350 rwhp Actual. That particular table will totally prevent you from getting the ERFS (electronic returnless fuel system) dialed in properly, which is EXTREMELY important in order to control fuel pressure, thus overall fueling. Sure, one can scale 4 known parameters to get more fuel flow room, but this is not ideal. Regardless, the MAP limitation is still the main issue.

Of couse, for aftermarket injectors, missing #3 will cause erratic fuel delivery.

#4 is not as important, as one can just raise the MBT table for now to get around that issue (but it's still not ideal).

What about the Base Rate for Upshift for each gear in the automatic transmission? I believe this changes the shift firmness.

I think you guys should take Eric brooks up on his offer. He is the man and the expense of the credits will be far out weighted by his priceless knowledge. Get some experts involved. Updates to the scanner are critical. Need to be able to detect knock and record more pids. Just my thoughts.

From what I was told by our head engineer we already have the information so thats not the issue, the issue is finding the man hours to spend on each strategy.

Eric thanks for the offer but we should be good.
