    Wont go over 40mph! (03 Lexus 2JZ)

    A 2003 should be setting some codes with that kind of problem.

    Hopefully it will go through for you. Mine took about 5 days after submission. I heard nothing after submission and wondered if the application was lost, not even a confirmation email from them. 5 days later I got an email that I was a approved and the cards were in the mail. My BofA card...

    What symptoms? Hot starts can be weird. Here's a datalog of one that behaves the way I would expect. This is a restart after a few minutes from a hot shutdown. Note that it essentially in closed loop right after startup and cross counts quickly. In the video VF Trim is a high resolution...

    Weird about the link, it was down for me. There are plenty of reviews on this card> Here's another one. http://creditcardforum.com/rewards/1251-chase-freedom-card-review.html They are a partner with Chase, so take it with a grain of salt. Note that the signup site has a Chase SSL certificate...

    You need to watch your cash flow. The $500 bill is due on your first monthly statement. If you don't pay it off you will incur interest charges. You will need to wait up to 5 months to get your $200 back, 3 months for the offer period, plus 8 weeks processing time. If you can up front the $500...

    You are right to be suspicious, but I am pretty sure its legit. I believe the $100 offer comes with 0% balance transfer, while the $200 offer does not. If you pay your statement off each month you will incur no penalties or interest. The $200 will be free and clear. Name...

    There is no way to tell if its active except by observing the FPU signal. Vf will behave like it normally does. It will be 0V when open-loop, then switch to reflecting the status of the fuel trim variables once the ecu switches into closed-loop. Since the engine will be running rich, it will...

    Yeah, I agree its a big investment for them, but it is also very strategic, focused, and ultimately a drop in the bucket compared to what they expect to get out of a typical new customer over the long haul. In a mature market like the US, getting a new customer is not easy. For them its a...

    Chase have been offering a nice deal of $200 cash back after 3 months if you make more than $500 in purchases. Not sure if that deal is still offered, but it was around in February. Yup, looks like its still around. For first time card user this is a good deal IMHO...

    3P's TCCS Disassembly/Analysis

    33-40 psi is what the manual says. Yes, I have the famous cold-start injector adapter with the schrader in it. I get ~35 psi. When idling, my manifold vacuum is usually 22in, so rail pressure is around 23 psi hot idle. "Are you bustin' my balls for a particular reason or are we just grumpy...

    3P's TCCS Disassembly/Analysis

    Yeah, that wasn't very clear or accurate! Assuming 19-21 in. for typical idle intake vacuum (-9 to -10 psi). Then, venting the fpr vac vent to atmosphere is going to add that much pressure to the fuel rail. Maybe 45-46psi would be better (across the injectors which will be seeing manifold...

    Funky starting issue

    They are fine. Be worried if they read a few ohms, or infinite ohms. My former boss would call what you're doing "chasing will-o'-wisps".

    There is some confusion on the fuel-pressure up (FPU) feature in the 7M ECU so hopefully this will clarify things. The FPU hardware when commanded on vents the fuel pressure regulator vacuum port to atmosphere. This effectively raises the fuel pressure by the manifold vacuum, so from 36psi...

    7MGTE fan clutch

    Well, here's a plot from a Lytron oil to air heat exchanger ES-0714. Nothing special about this one, except it had more flow rates plotted than some of the others. You can see that heat flow measured in terms of dQ/dT gets better with increasing flow rates for both the air and the liquid, but...

    7MGTE fan clutch

    Just to be clear, I'm no thermal expert. I can go talk to some down the hallway who are, but otherwise I'm just going on very creaky knowledge from my undergrad engineering physics classes. Overall heat transfer efficiency is improved by moving the air against and then away from the exchange...

    7MGTE fan clutch

    If someone can provide a peer reviewed paper or thermal physics text book that backs up the claims of so-called "residence time" then I might believe there is some truth to it, but frankly, I am of the opinion it is nonsense. I have discussed this with our scientists here at work in our...

    Need quick question Answered please Regarding stock ECU's

    Following the code 11 lead, you may have a wire that is going open circuit when the engine twists under load. With the car idling grab the harness at various places you can get access to it and move it around. See if you can duplicate the problem you see under load. Same with any individual...

    Fuel Pressure Up VSV

    JetBlue 191 may have an opening for one of you two. :icon_razz I am confused about this whole thread. Didn't he state in post #1 that pulling the vac line off the FPR caused it to run better? Seems like it could be the FPU, but then all his tests say its working okay?? Here is all I know...
