Got it installed. Wont run, VE analize says accel enrich fla

[Dubs Chops]

Well guys I got my mspnp installed. the car is running very rich after startup and immediately after startup. I logged it as i kept it running until my AFR guage would get up and it was showing like 11.5 or 12-1 I tried to VE analyze my log and I got a message 99% of your log has been filtered "accel enrich flag. Man I'm already lost

can you post the tune and log file

Looking in the background of your screenshot, your TPS signal looks very noisy.
This is probably causing accel enrichment to be activated constantly.

But yes a proper log attached will verify that.

Here you go guys, Thanks again!

I think it may be my MAP. I have the built in 4 bar. It is showing 96.4 kpa with the engine off and when I start the motor it doesn't move. Is there a was to calibrate this? should it read 0 with the engine not running?

[Blown88GT]

Let's start here:
1. Your tune says injectors are 0 lbs/hr. I entered 19 lbs & it gave the same required fuel of 20.8. Don't know why the 19 doesn't show in the tune. If you actually have 19's, it's good.
2. You are configured for narrow band O2's. Is this what you have?

[grom_e30]

agreed the tps is all over the shot were you constantly pumping the pedal during the log?

[Dubs Chops]

Yes I was having to keep pumping the pedal to keep it running. I have an LC2 wideband. I'll change that but I think I may be on a dead vacuum port on the manifold. Ill check it.

[Blown88GT]

Connect to the vacuum tree on the firewall.

[Dubs Chops]

I thought you werent supposed to share a vacuum source?

[Blown88GT]

There is only 1 vacuum source.

[Dubs Chops]

Well I have a good vaccum source now. I also set the MS to wideband. However it still dies as soon as the idle startup is over. I can keep it running with the pedal but no go if my foot is not on the gas.

[Dubs Chops]

Timing was also just calibrated and adjusted. I think it has to do with the after startup fuel settings

Here is my latest tune

Perform Base Idle Reset.
1. Warm engine to operating temperature.
2. Disconnect the plug going to your idle motor which is located on the front of your throttle body.
3. Start the engine, and set the idle to the rpm you want with the stop screw on the bottom of the throttle body.
4. Turn off the engine.
5. Reconnect the plug on the idle motor.
6. Start engine.

Shouldn't he also be making sure the valve is closed before unplugging it?

Awesome guys, It is idling smooth as butter now. Onto the O2 issues. I'll start a new thread for that though.

[Blown88GT]

...Shouldn't he also be making sure the valve is closed before unplugging it?...

No. When power is removed, the internal spring returns the valve to the rest position.

So, it was the throttle stop screw?

It's supposed to run rich after startup & will until engine is at normal operating temperature.

DUH...... Isn't there an emoticon for BRAIN FART??? I guess it's not a motor driven IAC, huh........

I axed my self that when I read that.

Then looked back through the thread and saw a 302ci motor and tfi ish settings and 2 wire PWM idle most likely ford and yes spring loaded idle air control valve.
