I think each oem has distict map burned in for high end. I also thought volvo's may have a better curve. If rising duty cycle at the top, mix would be more steady. But, may still need apexi safc to keep low end from excess richness. My findings:
1) LH 2.2 was only B230FT, 2.3L, M85-89?, with 160 hp/187 ft-lbs, mabe low impedence inj's.
2) The LH 2.4 in 780T started in M89 with 190 hp.
Might work out, really need to watch the duty cycles at the top end to see what's up with pulse width.
Based on various c900 dyno runs recently posted, 2 xtra injectors driven by 3D aquamist MF2 driver (see Brad) is a very good fix. I've asked aquamist if the MF2 can be used in parallel with lh system, and take over the stock squirters at the top end .... no reply yet. This may bypass the rev limit.
