Going on 4yrs now, and most significant gains in transient fuel increase I've seen is using TPS rather than MAP for entering PE fuel. Realizing #1 reason being TPS is it is the first sensor to realize WOT/PE, maybe also why the ZL1 stock uses it... as PE trigger via MAP reads 2nd (slower than MAP).. which is also probably behind actual intake port pressure change... why use MAP is primary PE Enrich? Also probably explains why the 2012-2014 Woodward Copo Whippled Camaro had 2 old (large) style MAP sensors hanging off the side of the Whipple... I was thinking... hmmm. if the stock 2008+ compact sensor isnt good enough.. then why are 2 1995ish large body sensors good enough? Any maybe they still arent? ZL1 warranty is honored by TPS PE alone.
All of the E38 Transient threads... how many of us are using TPS (basically Stock ZL1) PE trigger? I personally have been MAP based PE, because this is what Whipple suggested, and with my garbage fuel system (also supplied by Whipple) and countless MAP based PE mods, PE is always a bit late.. and still a bit lean in the upper RPM's probably because all of the Transient tables max at 100kpa.. but still I just cant get a simple upward bump in Injector Pulse during 4000+RPM WOT (between shift). Below ~3000 no problem... I get the bump in injector pulse at WOT tip in... but the "bump" at tip in seems to fade away above 3000rpms..
Did I mention the Stock 2010 Camaro LS3 Whipple kit IAT calibration gives you artifically low IAT temps? Yep! Check it yourself. My stock Whipple supplied IAT temp was ~60F while the Coolant temp showed ~75F after 10+ hrs sitting idle in a garage. Asked them direct about this... they dont respond. Yet they claim 15-30F reduced temps. lol
Today I went with the ZL1 settings, and instead of the Whipple typle PE (MAP based) dropping to PE target in the middle or end of TPS WOT and MAP WOT, it goes rich right at the beginning of TPS transition. While I may not get the "bump" in Injector pulse at Tip in.. it comes in way sooner... effectively giving me more fuel.. So another "why does Whipple do it this way" questions?
Turbo guys.. this is prob not that much of an issue as you don't see the boost spikes that whipples see. You automatically have what I tried to create by restricting my throttle opening rate...
