This 'discovery',

Bad, bad bad news for 5mt cars today, great news for all cars tomorrow! Raising the rpm limit is useless if the SVX maf is maxed at the power peak at 5600 rpm. I always felt that my 4EAT car was strong until 5600, and then just going nowhere and wasting time up to the shift at redline, relatively speaking. Do the 5 speeds feel flat from 6000 rpm up?

Would the SVX have a higher power peak in stock form with a bigger MAF?
With a bigger MAF and upgraded injectors? Let's hope we find out

This 'nasty little discovery' is actually good news for the future of 'LAN inspired' SVX power. EACH STAGE MUST COME WITH AN UPGRADED MAF [or programming for a 'standardized' upgraded maf], UNLESS LOW SPEED POWER AND DRIVABILITY IS THE ONLY GOAL. [NOT!]

Stages 1 and II could also provide upgraded [affordable] injectors if the stock injectors are near maxed as believed. Stage !!! already has the MAF, monster injectors and fuel pump, solving the limitation.

If each Stage supplies the same 'standardized' MAF and the appropriate injectors for the Stage, the door is open to experiment with rpm, cam timing, airflow, increased displacement, etc, etc. Stage 1 should have enough MAF and injector to support 300+ hp, a 30% gain.

Consider the SVX possibilities!!!

Anyone wanting more NA power than stock MUST HAVE STAGE 1 as a foundation. Anyone wanting max power will need STAGE !!!

Current Stage 1 programming is delivering power and drivability in the lower ranges, but the MAF 'discovery' opens the door to kicking up power to redline and beyond. Stage 1 REMIX with MAF and possibly injectors should kick a stock car every time, especially a Stage 1 REMIX 5-MT. Now maybe we will see stock weight cars with a few mods fun consistantly in the mid-90s mph range in the quarter mile. eg33 engine development begins now.

After LAN installed and programmed the MAF and the huge injectors, he implied that the car was strong. I wonder if the car felt better from 5600 to redline?

What do you say Michael? Stage 1 REMIX programming with upgraded 'standardized' MAF and upgraded [affordable] injectors, for the masses?

Somebody pinch me!

Anyone that was paying attention to the stage III development thread want to guess what's responsible for that lean out above peak power at 5600ish rpms? I'm about to get into doing the final software for stage III so I'll have exact #'s for you soon to verify this (I've made some guesses and interpolations here and there in the prototype software)...but it seems the factory mass air meter actually maxes out in a stock svx. The afr plots go north above 5600 rpms because the maf meter is maxed out.
