Acceleration Increase Fuel vs TPS voltage?

Post by Torque »

As per title what exactly are the mechanics of this table?

RB25 and Z32 seems to have this set differently ...

Once the throttle position (voltage) hits the value for the given RPM it then accesses the last column on the fuel map for injection

Hi ...

So does this mean that the Z32 (pink) does only enrich below approx 1700rpm (judging from the graph)?

Also, when is the table in operation?
Is it based on throttle delta?

TPS voltage signal. Should go red highlighting when this table is used

Based on that graph yes it would only come into play below 1700, more like 1,000 and it is set all the way high to 5.1v thereafter which is basically disabling this accel fuel increase feature because like most Nissan TPS max at around 4.1volts WOT so the TPS would never hit 5.1v essentially disabling this feature.

I was just looking at mine (GTIR) and it's set to 0 across the board. Will it still acess the last collumn all the time or in that case or does it work differently.
