Soon enough I intend to fit 440cc injectors, an ARC bar and plate TMIC, and get these remapped on my PFC soon after. (The PFC is currently mapped for: Walbro; Green; TD05; STi 2 TMIC; 380's; 7's; full 3" decat, ... at 1.1bar).

After I get the 440's and the new TMIC (std pattern) fitted, would it be okay to still use boost BEFORE the remap... seeing as it's already been mapped for the mods mentioned above?

If so, would I still need to rescale the 440s using the Hand Commander i.e. 380 / 440 = 86.36%, therefore entering the value 86.5? Also can anyone tell me what the 380's and 440's respective inj. lag times are?

 

It will be fine just keep it off boost. I drove mine with 550's front mount, etc etc for a good 100 miles when AF mapped it.

Just read the last bit, no do not run boost!!

 

IF you rescale your injector setting to 86%, you should be fairly close to the originally targetted AFR's on your old map.

You can also globally remove some timing from the map using the hand commander

This should be good enough to get the car started and driving - As mentioned above, stay off boost until it has a proper remap.

 

This is what I thought too.


However, if I stayed off boost, I wouldn't necessarily need to this though, right?


Message received and understood about driving OFF boost, lol.

 

STAY OFF BOOST
