Request for Pra k20 base map for 74mm TB

[Burnt_throwout]

Hi. I have a euro k20 installed into a MK3 mr2. I have got a 74mm throttle body on a ported and polished intake, stock injectors (might swap to RDX ones if required down the road). The k20 is stock internals with a nice equal 4-1 3inch header and 3 inch exaust with hi flow cat and straight through muffler.

It starts on the standard basemap but as it is a PRA ECU there are only 2 options for maps in k manager. And ideally I am looking for a decent map that I can put some road miles on the car with before dynoing it.

Does anyone have anything like this they could provide?

I do have a wideband O2 sensor so should be able to tweak fueling a little bit with the auto tune. Just thought I would ask on the forum for a map before putting the legwork in myself.

You should be able to run any of the Hondata basemaps. I would go with the one closes to your mods and adjust it accordingly.

The catch is you loose certain functionalities like reverse lock out , , depending on what ecu you are running.

Appreciated, I get a incorrect internal wireing code whenever I load a non PRA basemap so unfortunately need to use the PRA basemaps and there is only 4 to chose from. I suspect the best thing to do is open a basemap that more closely matches mine and copy values across to the current working basemap.

Since you plan to get it dynoed, use the stock calibration and dial in the fuel and timing. This will allow you to safely drive the car until you get it dynoed.

Got it dynoed and it made 203 at the Hubs so am happy with that.

Needed shitloads of tip in fuel which makes sense I guess.
