Yes, i had my truck on the dyno many times, just as ive had several blown Cobras and other mustangs on them as well.

I just didnt pick up this truck yesterday and become a newb with EEC-V tuning and dyno's.

However theres a lot of people telling others its ok to run a pulley with no chip, yet none of these experts have dyno sheets or af's #'s of there no chipped, 4# - 6# pulley to share with us

And i dont do mail order chips. I would hope if someone does, they still goto the dyno to doubel check their tune. To each there own. I just hope people see that there are dangers on either side of the coin.

Do you really think they are going to say something that may decrease the number of chips they sell?

Also I agree 100% with Tim Skelton. My decision not to get a chip right now has nothing to do with trying to a few hundred bucks. It's about trying to save a few thousand in repairs down the road.

Black F150, I am thinking the same way you are about driving the truck easy until the PCM has had time to adjust the "long term" fuel/timing tables. Wonder how long that will take?

Also like Crazyone said, it is a good idea to disconnect the battery on a chipped truck before a dyno pull or race to erase the adjustments the PCM has learned. But for someone running a pulley without a chip, this would NOT be the thing to do since you would probably want to wait for the tables to relearn before getting on it hard.]

That was my point. If we NEED to have a chip to compensate for modifications, then it would behoove the tuners to post and say such... more money for them! Otherwise, some of us might come to the conclusion that the chips are in fact detrimental and skip them alltogether... thousands of dollars lost revenue to the tuners. So, Sunday night... lots of posts and still no tuners have chimed in. That is very disapointing to me. Like someone said, they should know this stuff inside and out and should be able to give a informed answer. As a L owner running a chip done by "one of the big 3" tuners, I would feel much better if they would chime in and defend their products and/or reasons why we need to use their chips for the safefy/performance of our vehicles

 

Alright, after reading your post, I do agree that you have quite a bit more experience with EEV-5 than I do, but my point is that you can make the computer go into Open Loop all the time, and it will NEVER use Closed Loop. And you CAN make this safe to drive. I know that pistons begin to melt when everything gets too hot and I am not questioning this at all. You can compensate for this if you adjust the fuel tables correctly and tune it on a dyno. I did this with my car with a turbo charger and have had no problems. Any body else have any reasons why this wont work, this just maybe out of the ball park for the Fords! Like I said I am coming from a Chevy world but it seems that they are close to the same on this stuff.

Does anyone know by what means the programmers, program chips. There has to be an interface out there somewhere. Please let me know.

Just wanted to let you guys know that I will soon have dyno data to back up (or not back up) the fact that you can run a 4# pulley w/o a chip. My hold up right now is the local Ford dealership. I am waiting to get a bad head gasket replaced. The part is ordered and the warranty work should be completed this week, which means the JDM CAGED 4 pounder goes on this weekend (w/o a chip).

Here's my plan:
- Get head gasket replaced
- Install 4# pulley this weekend
- Drive it easy and allow the computer to adjust
- Hopefully I will be getting into the throttle good a few days after installation
- Run it on the dyno as soon as the local performance shop completes the installation of their new dyno (Lightninrod says mid-March?)
- Report the dyno results here as soon as they are available
- Report the track results here as soon as they are available

I have run a 13.48 on with the truck as-is (see sig) with F1s and a crappy 60' (2.11).
I suspect (and hope) for upper 12s (12.9s?) with pulley and F1s (with good air and good launch).
I hope for 12.7 - 12.8 with pulley and M/T ET streets that I plan to buy from Lightninrod.

Later,
Sammy

 

HMMMMM,

All this talk about chips, tuning and pulley's. Still no input from any of the tuners.


What's up guys......how about a little help here?

I thought I would throw this back up to the top to see if maybe the tuners had missed it from the week end.

Sammy, I talked to Steve at Reeves today and it's now going to be mid-April before the Superflow guy comes down to WR to teach Steve how to use it. He said it was already there but not installed yet. They will offer your choice of a Mustang-style dyno(Eddy-current) pull or a Dynojet-type(inertia) pull.

OK,

Lets ask this a different way. Will the factory computer compensate for 15 lbs of boost without risking a problem with detonation?

I would recommend a chip for the H.P./TQ gains anyway. It will still make the chip one of the best bang for the buck buys.

I just want to know if running 6lbs over is high risk without a chip.


Anyone????

I ran a 99 with just chip n intake and no mufflers...Never had any problems..except the intercooler leak...
50000 miles on the same tune..but there was a crate engine installed cause of the gunk..

10.5 or 11 lbs total is about the limit without a chip. This assumes 93 fuel and better plugs than stock.

IMHO

Did Danny Swanson do your chip? I've heard lots of good things about his work.

 

I talked to jason at RSI about this subject today. He said that as long as i got the colder plugs, tr6's or it22's, i should be fine with up to 6 pounds of boost. i have the 2# upper now and asked about a 4# lower in addition and he said i would be fine without a chip. He said i would gain more power with the chip but it wasnt necissary for that set up. what do you guys think? has anyone else talked to any speed shops?

 

i hope this is true. my truck will not stop pinging no matter what/whos program i use. with no chip it runs fine. im going to give it one more shot with a mail order. if this doesnt work im just going to run no chip and depending on the conclusion of this thread stay with the 6lb or go with a 4lb lower.

 

A lot of good information here. If you are running a chip and want to reset what the computer has learned do you have to pull the chip before disconnecting the battery? I have always been told yes but the comments here made it sound like you didn't have to pull the chip.
