[V88 For Sale]

I apologize if for sale posts are not allowed. 

My V88 from my last project is sitting on the shelf in the garage.  I planned on keeping it until the next project, but I fear that may be a while. With Christmas around the corner I figured I'd sell it so someone can put it to use.  It is up to date with the most recent firmware. Still have the original box.  No harness. $1300 OBO

 

[Vipec goes offline when cranking the engine?]

Is the ECU getting power when cranking? Depending on how things are wired up, some harnesses cut power to accessories (radio/headlights) when cranking. If you're powering the ECU off one of those accessory powers, then that would explain the power loss.

[Map Sensor Calibration Error]

Hit the sensor with 10psi and then some vacuum a few times.

My 3.5bar was doing the same thing. I fudged the calibration to make it work and then came back a week later and recalibrated it to the correct numbers. I think it just needed a bit of pressure/vacuum after sitting in the box for a while.

[Closed Loop Lambda and boost control issues]

I changed fuel pressure input to GP pressure and wideband average now reads correctly. That fixed my CLL. Thanks for the speedy work.

The boost control issue was caused by me putting in boost target as if it were MGP when it is actually MAP. Everything is fixed now.

Thanks.

Just sent them. Thanks.

[Closed Loop Lambda and boost control issues]

I think the CLL issue might be coming from it looking at the wideband average instead of the single sensor I have. I cant find anything that sets 1 sensor instead of Dual. The stoich modes have an option for dual on/off, but not auto.

Anyone? Fix doesn't seem to be fixing. AFR average is reading 0. With single wideband reading 14.7:1.

Changes

CLL (wideband mode) now uses the value of Wideband Average for measurement. This allows multiple sensors to be used.

Fixes

The wideband average parameter now also reads when only one sensor is used.

Testing CLL at idle. Even if I'm already around 14.7, CLL pulls fuel steadily until it gets to the -15% limit. Target AFR is 14.7:1 and it leans it out passed 16:1. Same on stoich or auto mode.

Closed loop boost control seems to go into stage 3 anytime it's on. It will go into stage 2 if I go into vacuum after being in boost, but as soon as it gets above the MAP activation pressue it goes to stage 3. Never goes into stage 1. Using the settings in the setup guide, 86kPa target with a ~86kPA wastegate spring. So stage 3 is 0%DC.

V88 on a subaru. Any ideas?
