17748 data log 418.xdl. 418nowbo2.xdl same bin with these changes 17749.
Big improvement! 17745. Here is a log without wbo2 parameters set. 17746. Shows a little more SA and the problem at 1500 RPMs is almost gone, which doesn't happen until it goes into closed loop. ...
My mechanical timing is set to 8.1 and the scalar initial timing to 8.1. My numbers are higher because I changed the SA value in the adx to 8.1. I never told you where my timing is set:innocent2: I'm...
In my ADX it shows as high as 44.6 SA. This is happening at 1500 RPMs and it loses a lot of power. When I start from a stop it gets to 1500 RPMs and will lose and lag if I don't gas it to 2000 RPMs....
I will not make changes again, sorry about that. This log is start, stop to try and point out the problem area17709177101771117712
I changed my injectors from 61lb to the Rochester 17084327 68lb HO 350 injectors from motorman. I'm tuning for 300HP so I set FP at 19.5 and was going lean. I logged data and used the wbo2 worksheet...
I researched what might cause that injector spike and pulled the injectors and changed the screens plus I checked the connection at the knock sensor, which was questionable, so I changed the...
17625 First couple starts were good and it wasn't so bad, but after 10 or so it has the problem between 15 and 20 RPMs. It's like the PCM is making it worse every time its driven.
I just looked at the log I posted. The wbo2 average data looks good but whats happening with the spark advance data? when I enable the perimeters for wbo2 to work in the adx (back pressure, linear...
17615 My FP is 23 so that should be 81 for flow. That log was almost undrivable, I cut it short. At the end I hit the throttle and it almost shut off
1761017611 I loaded that bin, set the wbo2 parameters so it will work and changed it to go into closed loop. Will do a log run in a hour or so and post it. Thank you
BJYK 95 342 gear. Thanks for any help, I've had a lot of help from this site and have learned more than I really wanted to. It's been years since I swapped the motor and started learning to tune. I...

The more I learn the less I know. It's time to pay. 95 c1500, 7427, L31R, vortec head, Edelbrock performer eps 2716, Lunati 20080660, flowtech 1154 FLT headers, no egr, wide band installed. Goes lean...
95 gmc, 7427 OD tbi vortec 350. I noticed a difference between the TPS and the MPH while trying to tune a hesitation when accelerating from a stop. As soon as I touch the throttle its moving but its...
I remove the air filter, unplug and remove the IAC valve. Pull the spring away from the pentil and screw it out a little at a time, (1/8)inch. Reinstall the valve by hand (not tight). When the pentil...
I raised AE TPS and it helped slightly, AE MAP comes in to late to make a difference but when it does it comes alive. Which PE table should I work with? PE delay is set to 0 in scalars. Thanks and...
When I start from a stop is good until 1500 rpms, then wbo2 goes lean and hesitates, and its good after it gets to 2000. When I put it in open loop there's no hesitation and it drives smooth. I can...
It’s a 7427 in a 95 truck. I’ve got the fans with the thermostatic switch installed and working well. Problems start when I connect the 12 volt wire from the A/C compressor to the relay. Don’t know...
I am installing the A/C and I need a request for the e-fans. I would like to use pin E3, can I make changes for that purpose only and not use the thermostat part?
I'm back at it, found the problem this weekend when i installed a rearview/backup camera. A lot of chalky corrosion at the fuse panel so I pulled and cleaned all fuses and now it runs great. Thanks...
It is a glitch when the timing drops below 0 degrees. But what is causing the timing to drop into the negative? I can load a bin file without the WBO2 perameter changes , and there is no negative SA....
I removed the UV eprom from the original memcal and read it with the burn2.14986 It is the calibration for the 305 engine that was originally in the truck.14987 I want to solder the 27sf512 chip...
It's the tuning hardware or software that is causing my problems. After setting, resetting, making sure I have good connections with the hardware and running a lot of test bins with no consistent...
