    Installing a Walbro 460 E85 rated pump? Learn from my mistakes here.

    UPDATE!! My stuttering problem was still here even after all of this fixing. Today I found out my GM 3 bar map sensor was spitting out some negative numbers during peak tq/wot. I am back on the stock one for now and that dang stuttering bs is gone. Chased my tail for 3 weeks checking...

    Installing a Walbro 460 E85 rated pump? Learn from my mistakes here.

    What happens when you make a hard right turn? Do you lose power to your motor?? I have left my stock filter sock (new one) and the recirc box on the pump. You would be amazed how well it actually works at preventing fuel pump starvation. I drilled a hole in the top of my fuel pump...

    No thanks. Someone else can use the money more than myself. I do not have any pictures so use your imagination or better yet, crayola crayons and posterboard. :D

    Installing a Walbro 460 E85 rated pump? Learn from my mistakes here.

    Yes and no. I found that if you rewire the fuel pump controller with larger feed and supply lines it can handle the pump..maybe. Isolating the pump from anything metal in the fuel tank and on the hanger is what normally fries the fuel pump controller. You will find if you search message...

    Installing a Walbro 460 E85 rated pump? Learn from my mistakes here.

    So, I was having a bucking/stuttering problem on the top end/peak torque of my road dyno pulls. This was not mild at all, it was violent and felt like fuel cut. I narrowed it down to the 460 pump I installed during my motor build. Let me tell you what I personally found to solve the problems...

    Speed density, stalling out, sick of it.

    Hey Oren, I fixed it!! I totally forgot about the ecu in my STI. When I flash a map it never resets the ecu like all the other subie ones. I think only a couple of the 2005 roms do this. My baja does not exhibit the same behavior. Anyhow, I used learning view to reset and then flashed the...

    I finally kinda sorta figured out how to use the merp github site. I grabbed the most recent 32bitbase.xml and am amazed by all the craziness that showed up when I opened a rom. :-O

    Speed density, stalling out, sick of it.

    I am still unable to see the tau tables. I cut and pasted this into my rom just like the other stuff you gave me. It looks like you are missing "type= level= scaling=" :-) Still waiting on parts so I can fix my misfire issue. NO tuning until then. :(

    Speed density, stalling out, sick of it.

    On a sidenote, I believe Oren is out partying this weekend so I am wondering if anyone has the tau tables defined for their 2005 sti?? I need to cut and paste that into my rom xml so I can see the actual changes he gave me on a map he tweaked.

    Speed density, stalling out, sick of it.

    Things I checked/fixed: Installed new fuel injector clips, old ones were a mess. Checked spark plug gaps, all were .028. I did get a good datalog today of the event. I did a 17 psi wot pull and it started to stutter again. It continued to stutter when I let off the throttle. I am guessing...

    Last page?

    How come sometimes when I do a search and the thread has multiple pages none of the buttons/prompts get to the last page? Instead I can only get to the next to last page??

    Where is my modding going wrong?

    Have you checked out kunigawa turbos for a reliable inexpensive option? I run those in my subies and have nothing but good things to say about them. For your hp goal a td06sl2 20g would easily achieve those numbers. There is a group buy on nabisco right now, check it out. Steamspeed is the...

    Reflash Limit

    I have a couple issues where I shit a brick and thought I was going to crash my ecu on both teh sti and baja. One time my puter froze up so I restarted it. The other time there was a failed flash on my sti so I just reflashed it. NEVER TURN THE IGNITION OFF until you see the success window...

    anyone have any utec experience?

    I have the experience of installing one, fiddling with it a bit and then selling it. That is all. I find open source more resourceful.

    Speed density, stalling out, sick of it.

    Really not a big deal. I needed data to diagnose the issue. I am running very mild timing and it does not knock at all. My egt's were nowhere near fatal. I will figure out the entire issue on Friday when I have more time to tune.

    Thanks once again!!! I will continue to tune. An example of the misfire lean stutter I was getting before I dialed in the sd map. http://www.youtube.com/watch?v=Dd4Os4lO0iE

    Okay Oren. I went out for some tuning today. One thing that has never happened to me before happened today. Once I get the VE table setup right and the car pulls like a banshee I noticed my engine load being maxed out at 4.00. What do tuners normally do at this point? Do I increase the...
