Here is my dyno sheet from my stock set up on 20psi well 20.25psi... A/F is good and i have seen very little(1.5)to NO knock on 20psi
yea he is but the heat is a killer but a 180*t-stat is a must and it could be the gas also cause ive see and had it before with a gas issue
Timing advance at initial WOT at 3k rpms in 4th was 23.5. I only opened the cut-out for tuning purposes since I read you run leaner with it open. Closed you run a bit richer. I have since closed the cut-out since that's how I normally drive the car with it closed.
18psi spike tuned no knock. If I go past 18psi it knocks. Could be the gas, I run 93 all the time. I run BP for the most part. Right now there's a mix between BP and Sunoco fuel in the gas tank. I'm thinking I should ditch the stock Mopar Spark Plug wires and get some MSD's as well. Like I said I'm running NGK 4306 gapped at .032. Could resetting the pcm have any effect to do with this? I resetted it when I put the s1 injectors back in. If it does, I'll lower the boost... reset the pcm... zero out the SAFC... and let the PCM learn and then try upping the boost and tune.
I don't even know where there's a Mobil gas station around here but I'll keep my eyes open. When I find one, I'll definitely give them a try. Thanks!
Those who posted dyno sheets... what boost and what injectors were you running at the time. Recall the mods?
Just got done doing (3) boost leak tests on my car. Only boost leak, which is small/minor, it seems to be leaking from the throttlebody shaft when I pressurize the system to 20psi. Below 18psi it goes away. Keep in mind this is with the throttlebody closed and with the throttlebody closed the car will never see 20psi. I'm thinking I may have thrown the pcm out of whack when I reset it, then went boosting around adjusting the wga to tune then immediately tuning the car without it learning. I already zero'd out the SAFC again and it goes to 10.0 afr's at WOT. So I'm thinking... I should reset the pcm and let it learn before messing with anything. Now should I throw in the S2 injectors before resetting the pcm, drive around let the pcm learn then raise the boost or have the boost already raised? Or should I just raise the boost and work with the S1 injectors. Just afraid I won't have enough fuel. I do have a Walbro 255 and a fuel pump re-wire. Someone please answer these questions. Any advice is greatly appreciated! Thank you!
throw the S2 inj in and reset pcm and beat on it but if u want put the S1 in and just watch your waideband
I would like to work with the S2 injectors since I have them already. Currently the S1's are back in the car. Beat on the car after resetting the pcm? I always thought you reset, and just get on and off the boost... once it hits a certain spike you let off and you do this multiple times until the pcm learns and just drive around. If your serious about beating on it after I reset the pcm, then I might as well pick up an extra set of spark plugs because the car will be running extremely rich lol and these new plugs I just put in a few days ago might foul out.
With the bleeder mod I can hammer it right after the ecu reset. Here is some fun info for ya. I did some data logging on the way to and from work. This morning it was in the low 60's so I do a 2nd to 3rd pull. I was spiking around 17.8 psi (map sensor reading) and I pulled 7.5* of timing around 5k rpms. Driving home temp was in the mid to high 80's same boost levels and I was only pulling about 3* at 5k. My mods on that dyno sheet were thermal exhaust, s1 pcm, and s2 wga. I found out after the fact that the line going to the wga was leaking bad so who knows how that effected it.
