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...
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
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...
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...
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
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. :(
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.
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...
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??
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...
