Since I got the t5,i notice on higher rpm i start to run out of fuel,around 6000-6500.I have not upgrade the fuel pump yet.But untill i do what can i do with the tweecer to make it a little more richer?I notice on the fuction maf transfer,I could go lean or rich.I went 10% richer and the car seem to run better,i was wondering if could go higher?Also i was wondering if i could mess with the WOT_FUEL_MULTIPLIER_VS_RPM without a wideband?Any help would be greatful. thanks Jesse
IMHO Jesse Any efforts with the Tweecer are gonna be unfruitful You are simply asking for more fuel than can be delivered Those two thoughts are based upon the fact you REALLY are lacking fuel up top What makes you suspect this Jesse I see you don't have a WB Seems like the auto would demand more load thus Dictate the need for even MORE fuel Sorry ... I just don't have much experience with autos If indeed ... the pump is causing an issue like I suspect ... any WOT tuning efforts done now could become inaccurate after you get a pump which has the ability to keep up with the fuel demands Tuning can only be effective if all systems are functioning correctly or Its very possible one could end up wasting a lot time and effort I have two recommendations here 1) Upgrade that pump 2) Forget about WOT Fuel Tuning until you have a WB in place btw ... I've never worked with that multiplier you speak about. I have used the maf curve and fuel table with success for wot fuel ratio optimization. Grady
The reason I suspect,is because in first gear at wot once i get to about 6000 its starts cutting out and then when i shift to second and the rpms get to about 5800-6000 you can hear it staring to cut out again.Making me think that the stock fuel pump cant give me the fuel i need. For the WB ,someone is selling one local,its a innovate wideband LC-1 for 250.Would that one work for what i want to do and how is the price on that.thanks grady Jesse
Jesse After thinking about it ............. Since you fattened things up by 10% you're just asking for that much more pulsewidth thus compounding things if what we suspect is true. About that first gear thing .................. See the thing here is all about load and how you load things up In first gear ... its all gonna happen quiclky Now ... Say you were in 3rd ............ You're gonna ask for more with wind resistance ... more load and You're gonna be asking for that load for a longer duration of time Honestly ... I just wouldn't be pushing it with that tiny pump Never Forget ... You don't have the benefit of elevated pressure Yes ... I've seen many others here use that brand of WB soooooo You can search out the details easily Grady
