Well, I finally went and hooked up on a dyno today. I was surprised. My superchip had me running lean and cost me some extra numbers, not much, but still......Now I have to get that part of it rteprogrammed to take care of it. I guess what I am saying is, if you get a superchip, than when you get the chance, dyno it and chechk for any changes to the programming you could get done to maximize the chip.

 

All I know is that I made 17rwhp with the chip as compared to without the chip

 

Talleywacker,

Nice numbers for a 4.2, got the curves? I wish some of the 5.4 trucks had sticks so we could see what kind of torque they are putting out down low.

Is the R9 a stock program or a "hot" program? Just curious, after seeing all the L guys with R9 in the sigs, I thought it might be a race program...

 

I've got an '01 SD 5.4L with the stick (5spd). I don't know about a dyno but I know the chip put a lot more power to my lead foot. I just assume that Superchip is giving you the best enhancement for your cp type. That's interesting that you found things to change. I wonder fi there will be updates to existing chips as the technology advances. It seems that every time we think a performance product is maxed out, another advance comes out. What do you think?

 

Ditto thewhiteford. My Butt-O-Meter gave similar results

 

got curves? as far as a posted image... no. R9 is basic superchip program

 

I would suggest Dyno-- Chip--Dyno.

Baseline plus change. I also would recommend making sure the engine is broken in-- say beyond 5k. I installed my chip at about 900 miles, dyno'd at 1600. See this thread:

Hello rooster,

Hang on here a second, let's not start making people paranoid about their A/F's.

I see no "before" the Superchip air/fuel ratios, nor do I see any "after" the Superchip A/F's, so perhaps a good place to start (that is, if you wouldn't mind filling us in a bit) would be a list of modifications to the vehicle, the air/fuel ratios *before* the Superchip, and then the air/fuel ratios *after* the Superchip. That would begin to tell the story, so to speak.

In general, the standard Superchip for each of these vehicles computer codes is NOT going to cause an engine to run too lean unless *something* else is going on, either a marginal O2 sensor, an EGR issue, etc., or something with the vehicle that we're not made aware of up front, such as other mechanical modifications, a superchjarger, ported cylinder heads, etc. YOu can run the Superchip along with things like a K&N air filter, an Air Force One kit and a cat-back exhaust system, and not have any A/F ratio problems.

A supercharger, an aftermarket MAF, etc., *something* else has to be on there to make it go "too lean," generally speaking. Just having a stock to lightly modified F-150 (meaning, no aftermarket mass airflow meter or throttle body, no supercharger, no headers, etc.) and putting the Superchip on there is not going to make it run "too lean" in a vehicle whose A/F's were correct before the Superchip. We've done more R&D in our performance tuning on F-150's than any other company in the world, by a large margin, and the A/F's are perfectly safe.

We own these F-150's as well, and every one of them, along with every other vehicle we've had here at Performance for over a decade, has been running the Superchip, almost all of them have been on a dyno and have had the A/F's checked, and not once have we needed to adjust the A/F's in any of our vehicles.

Rooster, if you have some hard data, like maybe the A/F graphs, etc. I'd love to see it and go over it with you, if you need any kind of tuning adjustments, etc. You can just fax your data over to us and I will *personally* be happy to go over this with you.

I'm responding here (and I've edited this post a bit since I went back to re-read your post to make sure I didn't misunderstand) not because I doubt that you could have made more power with more fuel, that could easily hapen depending on state of modifications conditions at teh dyno, etc., but I'm also just curious as to the vehicle configuration and the actual A/F's etc. And of course, this is all *assuming* that you and I have not already discussed this over the phone.

Just to give everyone an idea, things like a K&N air filter, an airbox elimination kit, and a cat-back exhaust system can all be used with the Superchip without any worries of a too lean condition.

Interestingly enough, we had a gentleman the other day I spoke with, who was very concerned about his A/F's during the upshifts, he had a supercharger and was running on the stock factory program. He had an FMU with his blower of course, so that was fine, but he went 18.0:1 A/F during the WOT upshift for a fraction of a second or so, and then it went right back to where it should have been, and he was very worried. In that case, it was nothing mroe than Ford's soft-shift implementation in ht efactory program, which also reduces timing and fuel delivered during that upshift, and *that* was why he went lean very briefly during the upshift. We're taking care of that for him in a custom program.

It's funny when we're here on F-150 Online, I don't know who most of the people are by their screen names, so I don't know if this is somehting that you and I have perhaps already discussed, or if we're going to be doing some adjustments for you, etc., but just in case it's not, please do feel free to fill us in on exactly what modifications you have on the vehicle, etc. to give us a bit more of the picture. And of course, if you got your Superchip from us here at Performance and need any tuning changes, just give us a shout!

The sky isn't falling, folks, youy don't have to run to a dyno just because you installed a Superchip......................

However, if you have *major* modificaitons like a supercharger, it's nice to get those A/F's for fine-tuning, etc.

Just give us a shout if you need a hand, Rooster, & thanks for your post!

 

OH MY GOD, THE SKY IS FALLING!!!!

(Sorry Mike, I couldn't resist!)

Mike make a good point that I forgot to mention in my previous post. The methodology still holds however:

benchmark (baseline)-- Measure
change (test)-- Measure the same stuff again
conclude-- sometimes this takes more than 1 measure

Hehehe-- Chicken Little.....Hehehehe

 

Mike,

I am not casting random disparaging remarks about the chip. I did not run my truck on the dyno before installing the chip. I am not aware of any O2 sensors going bad, I am not saying they don't, but I had not heard of them going bad so I did not think to look into that possibility.

Also, I posted just a brief note about the results of my run. I saw another 4.6 run with a different A/F result. On all three of my runs, the A/F was right at 14. On two of the runs, around 4900 to 5000 rpm, the rstio dropped to around 12.8 on one and 12.8 on another. Actually, the norm was 14.6-14.8.

I do not know all about these matters, I merely relayed what the operator of the dyno told me, and another member who was there.

As for the mods, the only thing I have done is added true dual exhaust, H pipe and a K&N FIPK, no MAF or throttle body. It is not supercharged or has had Nitrous added.

If the meaning of my post was taken that everyone needed to dyno their truck as a matter of fact after installing the chip, then I apologize for seeming that way. What I was saying was that at some point after installing the chip, they might want to dyno the vehicle to see where they are and if any changes need to be made.

I was not saying that the chip is not made right. However, I have read of people having problems with their chips, (rare posts), and they are by no means perfect. It is a fine product and I will continue to use it, but if there is something wrong I do want to work with someone to correct it. On the same note, it is possible from what you say for a stock part to go bad. If that is the case, again, I do want to find and correct the problem.

I did email you with the same information about the numbers. I will also be more than happy to fax you the paper on all three runs for you to try to help me figure out what the problem is.

Again, I did not intend to make an attack on the product. I only made a comment about a paroblem I found and a possible solution to it from what I had been told.
