The last 5.3 my buddy setup only made 329rwhp, which I've seen STOCK 5.7's pass up with 26 pound injectors. As said though, I will bump the pressure up if it keeps you guys happy since I'm at your...

Stock are 24 pounders, but I'll stick it at 58psi and set the injectors at 36 pounds

Not at all. Its a 255 Walbro, but at this point and time, I see no reason to run the injectors at 58psi on this little 5.3 unless they have a better atomization at that PSI or something. Its too...

Because lowering it takes the pressure off the fuel pump (pun intended).

I thought they were rated at 39psi, so I'll set the regulator at 43.3psi and go from their.

The AFR's are sitting right...

As far as injectors, they are the red top SVO's which are rated at 30lbs, but I've never really seen a clear PSI on it, so I plugged them in as 39 pounds being the original number.

I copied the...

Fuel pressure is at 38psi using an adjustable regulator without the vacuum source.

As for tuning order- stock file was rich so...

I started out with the 5.7 file, plugged in as much as I...

I changed the PE MAP Enable to 80kpa and it changed nothing. Does any tuner want to take a stab at this and let me know what I owe them? I'm at my wits end and am ready to just part it out, shove a...

Beings that the car idles around 65-70KPA, it looks like it is in PE mode all the time. Should I increase the MAP KPA to 80-85 before it goes into PE mode? What about the MAP Hyst?

I'm trying,...

I've played with the idle VE's and adjusted the IFR/KPA table for the SVO red top's at my 38psi of fuel pressure. I even set them up to think it was at 40psi of fuel pressure, but it didn't seem to...

Anyone have a how-to on hooking up and setting the AEM Wideband? I had it setup years ago with the right PID, but it took hours to fumble through it, and I'd hate to do that again if I don't have...

The newest file- It made the car run better when pulling it around the barn, but it killed idle (easy enough to fix). It also left the WB02's at 10.0

Will you guys be playing with the older 5.9's? The VP44 and common rail trucks.

Printed, read, and changed.

When looking at my scan, it says my narrow band O2's are reading lean from what I've been reading on the web. The exhaust smells like fuel (no cats so I don't know if...

Sorry for bumping this back up, but I hate making new threads when this one has some pertinent information. I'm trying to remember this tuning thing and it is not working for me AT ALL. Finally got...

All squared away! I don't think Bill sleeps. We've emailed back and fourth at all times of the day and night and he's almost always had a response within an hour or two. :)

Good idea. I'll grab SWMBO's laptop and try it out.

the 6.7 might take awhile. Dodge locked it up TIGHT. The guy who builds the SMARTY has been working for about 2 years to crack the code dodge put in to their "update" on the PCM's.

I'd be...

I'm dealing with the same thing right now. I need to right the application key down on my HPT device so I don't lose it again :(

Email sent to Bill!

Could it be from anything else? I've tried two vehicles now, and both work fine with my simple OBDII scan tool

Seemed to have fixed that. Now I'm trying to deal with "off idle" power being very weak. I really have to rev it up to get off a stop light or you'll kill it, but on the highway, it will not buck...

Got that part now. Still working on Idle tuning.... but I need to get the car out of 4th gear first... time for a transmission rebuild :(

Im having the same issue!

How do you go about making a custom PID? All my historgrams are showing 14.9-15.0 agerage and the LTFT's are right at 0 to -1. RTT has been of great assistance for...

I have had the wideband installed for some time now, and am just getting around to hooking it up on HPTuners to do all the VE tuning with it. I have the White wire on Pin 1 and a ground wire on Pin...

Bumping this up

Do you change the idle VE table while you are in RTT?

My car idle surges badly when rolling upto the stoplight, but once at the light, it idles fine (on a 1999 C5 with a 224/230...

Do you have another version laying around just so he can start HPTuning? If I'd known i'd been holding him up this much, I would have had it all ready to go before putting my older version on the...
