so 10.0 is rich and 17 is lean as fugg right?

whats a good setting for cruising?
whats a good setting for WOT?
whats a good setting for idleing?

i got a AEM wideband on and at idle it kinda sits there at 14.5-15.1.... when i go to give more fuel,

i go to gear 1 (boost per gear) and pull from TPS 25% right? DTEC-FBC


well i do that and its stays there at 14.5-15.1..... can anybody help...

At idle/cruising you should be at 14.7-15.1 range, depending on your tuning/mods at WOT you should be somewhere between 10.0 and 12.5, 12.5 being more in the range of meth needed.

see at WOT it kicks over to 10.0 but before it gets there its at like 14.5-15.0 not until full boost will it stay there..

at part throttle it doesnt matter what you are gettng unless you are running a full stndalone fuel management system. the reason being is that the car runs its own variable part throttle fuel mapping tables at those parameters. at full throttle it switches to open loop mode and the PCM doesnt intefere QUITE as much with the mapping because it for the most part just defaults to base maps at that point. there is still input going from sensors to PCM, but they are all signals that you can intercept, interpret, and alter if you choose to. it really is not worth the trouble to intercept interpret and alter the part throttle tables on the factory PCM because there isnt enough load on the engine to cause any real problems. even under massive part throttle overboost with the stock turbo and PCM i still get zero degrees of knock retard, and that is on shitty cali 91 gas..so i think that is testament enough to show that it isnt really worth worrying about unless its presenting driveability issues, which i did not see you post anything about.

just worry about WOT because thats when the car is under the most load and will start to be adversely affected by any improper tuning decisions.

if you get a standalone, prepare for ALOT of time building your part throttle tabels. most guys can get the WOT tables right in the first day of trying if they work hard enough. the part throttle tables take months and months of driving, pulling data, correcting, and repeating the process under all different types of conditions......

yea but DTEC is not a standalone. it is a good tool, but stil not a standalone, so you dont neeed to worry about your part throttle tables, the factory PCM will take care of that. unless you REALY want to spend the time to intercept it all, then by all means go ahead, but the car will run fine as it is.

My AEM reads 13.8-14.1 at normal cruising speeds. Is that OK?

that's a little rich, but it shouldn't hurt much...

"usually" at part throttle my aem reads 14.3-15.3, most often at 14.7

cool same here... i noticed though that in second i hit full boost and readings are at 11.9-12.2 but in third its like 10-11

That's due to the 80psi ptp fpr mod. I was just wondering if that was ok. Thanks for clearing that up for me!
