If you click the top column header manifold pressure.. (its underlined) you can edit this axis to suit your needs. I do this daily.

That hump at low RPM isn't a bad thing. Lots of setups/cams...

One side of the motor is super lean or missing.

I'd check fuel pressure too.

yep I was going to say the same thing..

try this..

if it doesn't work. get a log with it not going past 4000.

What PCM service number? If you happen to have a 411.. i always recommend 2002 F-Body for swaps.

When you say no start.. is it turning over and not firing or not turning over period? Has the...

Somewhere between 30-50 fully warmed up is pretty good. I don't like them to be 100's fully warmed up. You need reserve for when it is cold.

I would put all the follow and cracker stuff back to...

After the changes I recommenced you would need to go back over the tune.

Again I'd be wary of any map sensor that wasn't an OEM GM part.

There is nothing wrong with the 80's.. But they are a full generation behind what is out now for them. They do not run as clean for sure.

Did I read that you want more resolution in the spark...

I do not do this and do not have a problem with them coming out consistent.

hard to know without seeing a log of it in SD.


It looks reasonable to me. However numbers in VE should pretty much always be increasing with MAP. There is a little hump in 2400 that likely...

Since this is a swap...

The GMPP harness install instructions have a section for pedal height vs brake pedal height. This seems silly.. but I do a ton of swaps.. When this geometry isn't correct...

As someone who lives on a chassis dyno..

For most NA applications there is no power to be had with a throttle body.

I've had 600 rwhp NA max effort cars pick up maybe 5 rwhp.


They are...

That's not how that works. The 2500RPM you have set in your tune is to enable/disable dynamic airflow calculations. Both MAF and VE are active always.. The weight goes to one or the other more...

I don't think this works. Prehaps they fixed it.

more than a decade ago I was trying to make a interface box that took that signal and convert into on/off for electric fans as an option. I...

It sounds like you are bothered by the difference between stock. The WOT shift point OEM are programmed to shift super short via MPH.. They basically have them waiting on the RPM qualifier to...

Perhaps its the way you are calculating it.

I'm not a fan of using the MAF to dial in VVE. Try disabling the MAF entirely and see how VVE stands by itself.

Supercharged/turbo charged watercraft have been that way for a while. Lots of boost and traditionally very lean AFR's.

I'll bet in both situations getting fuel to them would make more power.

You don't have STIT logging. Maybe I missed it.

This your fast idle airflow trim. Work on getting it to zero or slightly negative. like -0.5g.

I'll bet it is very negative right now and...

Sounds like it's got a REP type DTC going on. Make sure you scan it for codes while you have no pedal response.

This needs a lot more cranking airflow IMHO.

it also looks like VVE was roughed in but not tuned. Tuning this will make a good difference.

Have you looked on the tune repository for a stock file?

I'm fairly certain I would have one. You might have a export OS though compared to what I see here in the states.

AFR reported depends on what Stoich is assumed to be.

If this is an analog output AEM I have a spreadsheet to help find the real transfer function for your wideband as you have it installed. ...

I would try looking up VVE tuning. This looks like it hasn't had any. This will make a good difference in just about every issue you list.

Also looks lazy getting into PE and low on timing at WOT

2-3 g/cyl across the board will work on just about everything.

Maxing that table in some years causes a instant code. There are two codes 1514 and 1516. One is a tune issue.. one is a...

It could be just knock sensors. When they go bad, they get super sensitive or very quiet. Torque is important when installing new.
