Thanks a lot

I'm looking for where in hptuners to look for what's causing this.

On cold start, it's like the first 1/4" of pedal is dead, then it hooks up and you jerk.

As soon as the engine is warm, it's...

I've got 2005 with DBW gas pedal assembly. And it's reading 7% to 10% when the pedal is totally up. I unplugged the pedal assembly, turned on the car, freaked it out, then plugged it back in and had...

Well, I'm glad you figured it out. It would have never have occurred to me that the banks were swapped.

Ya but ... I had to put in a tire size 2" different than my actual size to get the speedo in HPtuners to read right. So, double check. You want the speedo in HPtuners to read right - check it against...

They only recommend disabling PE when you're trying to dial in the VE table so PE's changing commanded AFR isn't screwing up the trims. It's not intended for long term use.

Don't let the blower freak you out. It doesn't change anything - really - except extending the VE table from 100 to 200 or 300. It's really not that hard at all and the stock tune will work to get...

YES! Fix that! God, I feel bad for the PCM.

Did you also install the 3bar map sensor and install the new injectors? Or did you just change the software? Just checking.

Where is the LTFTs go? They are all zero. Did you disable them?

No, I mean the throttle is very sensitive. There's there's nothing and then it jumps. But, looking at my last log, TPS is ever below 8, so I'll fix that first.

You'll need to put the new injector data in the tune.

It should just start. However, you need to know what injectors they (or you put in). Did you get high flow injectors? You can find the data for them online. However, with the right injector data, it...

Well, off the bat, the LTFT Bank 1 are way rich and the LTFT bank 2 are way lean. If the O2 sensors are working right, then you've got a mechanical problem. You aren't logging a lot of data, someone...

What engine is this?

We mostly go off roading in this ('84 LandCrusier with blown 5.3/4l60) and it's always had a touchy tip in that I want to eliminate. I searched, and can't find anything applicable. I'm not sure where...

I wish I can help. I can report that mine freezes on occasion - but not nearly as often as yours. What does customer support say?

jayss - the LQ4 is a 6 liter, you're not going to get that good of mileage out of it.

waynehartwig - I agree with the suggestion to find a 6 liter tune with a manual (they are in the repository)...

I did same thing. I can tell you from personal experience, you're either going to have to invest a lot of time to learn through experience - cams are a bitch. Or you can just take it a tuner you...

I can in the tuner, but I'm not aware I can in the editor.

I'm not familiar with custom OS stuff. Not sure I'm there yet.

Not really, I'm tracking cracker and follower and they clearly aren't the culprit as you can see follower coming and going very quickly. Cracker is totally disabled. I can't see overspeed taking any...

My experience was that as I spent more time dialing the tune in the spikes went away. But yes, you can't leave those spikes. Either spend more time tuning VE until you work the spikes out, or use the...

When you create a graph in the scanner, there's a section called Maths and in it there's a LTFT+STFT that gives you what I think you are looking for. However, I also use LTFT bank 1 and LTFT bank 2...

So, good time for your first log. Add TPS and MAF hz to your log and see what they do.

What's your question? It's a legitimate code. Possible causes are are listed as TAC or MAF.

Have you cleared and see how soon it comes back?

I assume you have HPTuners, have you logged TPS...
