You do not HAVE to use them. It just helps. On pretty much anything that is still N/A, it will be fine.

To be even more specific, with key on, I get 4.8V on PIN A according to this diagram. On all other pins, I get 0V. This is with KEY ON.
...

So I checked the wiring on one of the wires at the O2 sensor pigtails, and on the heater circuit, I only got 4.8V on the heater circuit. The other wire for the heater circuit is 0V. Aren't I...

You are right, I can check for the 12v at the heater terminal. This would be a good thing to do. Also, to be honest, this car is so low, I can't even look under it. It will be a challenge to lift...

Ok, I think I have this figured out, but I wanted to run it by some other minds for good sake. The vehicle I am working on is a 93 RX-7 with H/C LS1 and T56 swap. The O2 sensors will not do anything...

Ok, I'll try that.

Not sure if this is the right place to post this, but I think I may be having an issue with the forums. I cannot see anyone's attachments. Every thread I look at that says it has a tune attached, I...

Man, I never updated this thread. Well I will update it right now, just in case someone searches for it in the future. I'm sure there are all sorts of issues that could cause a car to break up as...

Just wanted to update this thread. It took a second before I could actually tune the car again. But, to summarize real quick, I was worried about my injector data, because I found out that the...

I'm curious if this is true. I guess you could easily just zero out all vve and ve table stuff and check logs to see if you ever have any irregular injector timing values, but I am not interested...

Yeah, but I hear the 4L80e swap is a nightmare on the AWD models. And I am not one of those guys that convert their cars to RWD. Sorry about your luck with your trans motorheadmike. I would be...

Either way, you can try to read a file with EFI Live to see if it will work. And if it doesn't, as long as you kept the original file from the car, you can just flash that one in, and write entire...

I would be interested in this too, as I have an AWD TBSS also. Mine is cam, LTs, custom exhaust, CAI, efans, LS7 MAF, and a 3600 stall. I left my torque management in the tune for sure, because I...

If the truck is fully stock, why are you wanting a max performance trans tune setup? You will be just fine by decreasing the torque reductions between shifts.

That is exactly correct. Copy and paste all of the 10 values, and then just interpolate between the 2. This is the correct way.

I have always tuned part throttle areas up to whatever the value is for dynamic calculations. Usually that is 4000. Past that, it will read filtered MAF values only, so it doesn't even see the VVE...

Did you perform a write entire when you did the segment swap? If so, maybe try to write entire one more time. Only thing I can think that would have gone wrong by doing that. I am at work, so can't...

Man, I hope so too. I am way past due for figuring this one out.

Good observations GHuggins. Man, it is so hard to tell a customer that they have a bad ecm. It is a very expensive thing to try out. but I know what you mean. If it's bad, then it's bad. That's...

Would anyone have some insight into maybe why the follower decays so quickly? My calculations show that it should take roughly 3-4 solid seconds AFTER the 1.2 second delay for all follower to decay...

You've probably heard this before, but you only need 3 things for an engine to run, fuel, spark, and compression. And all of those at specific times. lol I would just start there, make sure it is...

Hey NJ_Phil, I was going to mention that when I posted the file. I think something was wrong with my scanner, because the car was running PERFECT during those times. With a commanded IPW of that...

Yeah, I started to think about if it had any kind of issues with the hardware. I did the heads, cam, lifters, springs, pushrods, fuel injectors, and head gasket install. Everything went fine. I am...

Updating this thread. I made the changes to the VE, and then I also started messing with Throttle Follower. I am just at about wit's end with this car. It has been a curse to me. I go out to...

Well I guess I could have solved that mystery by logging dynamic airflow and comparing it to the MAF airflow value.

Good catch on the throttle follower, I thought it was just off of tps %. I...
