I think this might have a brake switch issue. TCC operation will be funky also which might be your 3-4 thing.

See if this makes it feel better in the meantime.

Find out what he got for sure.

What was in the kit you bought.

I wouldn't buy anything like this from amazon. Too many counterfeits.

I'd get rid of that cam. The only thing it would be good for is the sound.

have you made sure it is filled all the way to the full hot line?

At 14 min the car was at 1700 RPM very light load with map in the high 30's. I'd honestly expect a little bit of a fish bite surge out of that cam there. Going up one gear (lower RPM) but higher...

Is that all the turbos you have will do?

I know you said it has fuel pressure but is it building and holding pressure on key on?

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.
