Transition ignition map

Recommended Posts

hi,

 

i have Vipec I88 wire in ecu, about the same as G4+ Extreme.

Whanted to set transition ignition control on Rpm VS map Delta based.

But the ecu doesn't let me set - negative values only positive.

With TPS delta negative values is no problem as Y axis.

 

Is this bug or normal that i can't set negative values as axis with MAP Delta?

Hi,

This looks to be a problem not with setting negative values on the axis, but that MAP delta has not been setup to go negative. When I look at the parameter info it looks like the lowest possible value is zero.

I will ask the engineers about this.

when you  set logging on for tps and map delta.

they do go both negative when release trottle or when shifting.

only the transient setting doesn't  allow negative value as axis. i prefer map delta ignition retard over tps delta ignition retard.

Hi,

Looking through the firmware and PCLink revision notes I cant find any changes on this, but when testing my ECU with 5.6.4 firmware both the TPS Delta and MAP Delta can go negative.

Offline in pclink you van enter negative values, but when you whant to save the pcl, it says "negative values not allowed".

When connected to ecu, i can't even enter negative values.

We will have pre-release testing available, but are still working on the next PCLink and firmware release, so will still be a while yet. Send us as email on tech@linkecu.com if you are interested in helping with the pre-release testing.

Scott.
