also, any plans to run n1 cams ??

MAF emulator is a hardware fuel controller made here locally.
It takes MAP sensor data, RPM data, throttle position data, IA temperature and converts it all to MAF signal acceptable by ECU. Not a bad device, have a plenty of features for $350. It even contains two (or four?) RPM switches, so you can sell your Greddy MSS and use this one for all of your tuning needs. I can find a user manual and post it here translated if anyone interested.

Nistune fuel map untouched after switching to MAF emulator. It have a great datalogging capabilities including wideband logging, so I tuned fuel by MAP2MAF tables inside MAF emulator.

Injectors and fuel rail are stock 20V (350cc).

No plans to run n1 cams on this engine.

I think this is not the only length matters, but more airflow, velocity stacks, more stable A/F ratio between cylinders because of no receiver at all.

This is a little Ukrainian company. I didn't sure they take orders overseas. I can help to buy their stuff if anyone interested.

BTW, I have one slightly used device to sell for $300.

Nice!

Was the tuning done with the 'socks' on the trumpets?
As I have heard they can kill power.

Also have you opened the block to see what killed the engine? bearings?

Yes, tuning was made with a socks. I know they killed some power.
Engine was killed by cracked piston. Too much 9500+ rpm runs for stock internals.

Here's another one Map Ecu They pop up on ebay every once in a while. I always believed ITBs sacrificed low end for top end...
