I finally got around to joining 2012 with a wideband and ditched the ol' narrowband gauge. Not surprisingly, my readings are not close to what I had been seeing.
I get a great bounce around stoich at idle and cruise, but at WOT it goes to hell. I had my boost set around 14psi and was getting a "safe" light with the old gauge, but the wideband was reading up in the 15-16 range:yuck:. I've now got my boost all the way backed off as far as I can, 8psi and am seeing readings in the 13's at WOT. This is not good!
I figure either my fuel system is not up to snuff or I am flowing too much air for the factory MP computer to compensate for. The guy I got the SBEC from had the owners manual which is pretty neat, it clearly says that this is intended for a stock T1 engine with no modifications. I have an intercooler, larger turbo, modded exhaust and a boost controller. Could that really overwhelm the MP computer under WOT situations?
I will check the fuel pressure first, but if that checks out I might throw in my set of FFV injectors and see if they bump it up enough. I really thought it would be pretty close but I guess this is why people say to get a wideband in there!
