Are you using a 97 PCM? I don't believe the older 97 and 98 PCM's have that function available.

The 99-02 style do and that's what is shown in the second image.

Get an Innovate LC1 or LC2. I have an older LC1 attached via serial port and log direct into HP tuners. I don't even use the Pro-inputs any longer when using serial. I have a pro but std would be...

I really need some input on this one. This is for a good friend of mine. I personally don't know much about Ford Tuning. But have done a lot with GM stuff.

The truck is a 2004 F150 5.4 with a...

Could be he isnt using a newer tuning program like HPT or EFIlive. Either of which will allow OS rewrites. Probably using Old School LS1Edit. This would make it harder to tune with the secondary VE....

You have a problem in Bank 1. You car goes +25 in the LTFT's and 30+ in STFT's. You also have a ton of misfires. or reported misfires. Something is up, that may prevent the car from going into closed...

Basically, command what A/F ratio you want with the PE table. 1.0 = 14.1.. etc.. Then you figure how far you are off from the commanded using the wideband O2. Then adjust your VE OR MAF table...

No power gains... However you will eliminate the stupid secondary VE table which is kinda a pain in the ass. Also, there are a couple other lil things, but that is really the big change.

You can...

I would try unhooking the battery for like 15 mins or something. To make sure all the codes and junk are cleared.

I'm running 2.2.0 and the car is a 2001 C5 vette with the 1-bar SD OS applied. Computer is XP Professional with all the .NET stuff applied. 1.1 2.0 and 3.0.. lol

When i'm in imperial mode in VCM...

bank 1 still has a problem. Here is a link for the green tops.

Ok.. Looked at your new log. I believe you have a physical problem on bank 1 (driver side). The LTFT' and especially the STFT's are off the chain. The negative trims on bank 2 are because the PCM is...

I have done this too. It does work. simple swap.. takes seconds. Arun, you still having issues with the 2 bar?.. That sucks man. I think the 2 bar SD is much easier than the MAF especially with the...

You can try that, but you will have to play with it. Every car is different. Don't have a copy of my tune handy right now. You can do a search on the tune repository, as there are a couple cars on...

I have heard the exact same thing.

Question.. if you have a stock longblock... why are you running 65lb injectors?

Disable the MAF and do some work on the VE table. You need to get the trims down. You can disable the LTFT's and use...

If you are sitting there in park and it keeps dying, you need more timing in the idle spark in Park table. Looking at the scanner log, It's getting like little to no spark in park when it drops and...

I'd bet on a combo of the injectors and pump running out. You really need 60's on that car. And I'd try a boost-a-pump if you keep the single 255lph. Was the fuel pressure taking a dump?

They can only be deleted on 01+ cars with a Tech II. On 97-00, they can't be disabled in the BCM. The reason they can be disabled on the 01+ cars is that it is an RPO code that can be disabled. The...

what MAP sensor? 2 bar or stock 1 bar? With the stock os you need a 1 Bar MAP. With the 2 bar you need the 2 bar MAP or scale the map settings for a 1 Bar sensor.

Just do a full reflash using your stock file before the 2 bar was applied...

Also.. YES a 2 bar OS will still read the MAF. I'm doing it right now running a MAF tune with a 2 bar os..

Ok... yes I do have a wideband and was doing alot of it in CL. I wont have access to the HPT logs til this weekend. I plan on doing more scanning and tuning on sunday.

Here's one issue though. I...

Anyone have any ideas??

I have mine in one of the rear bungs for on my LG headers, since it has no rear O2's..... Didnt even want to mess with the fronts and the wideband emulating the narrowbands

Guys I'm having some issues getting my VE right. The car runs good and has power, however the VE table looks like complete ass. Bad looking, All spikey and especially the deceleration area. It kept...

Yup.. I agree.. Same thing here and yes it seems like a C5 only problem. My tach and speedo dont work as well as the oil pressure when it happens. It's happened a couple time.. just do a rewrite...
