    Hurt my '94 Vert on the Dyno :(

    I went to the local dynojet yesterday to try to get a baseline for my mild 331 daily driver. I had a premonition that the day wouldn't end well. First run went 288HP/342T. A/F was 11-12. I took out 10% fuel, and went 297/345 but A/F was unexpectedly 13.5-14. We didn't hear any pinging. We...

    another mishimoto problem

    Yup, I went through three of them. They hold for about a month. They leak from the top three rows on the right side. Thier warranty coverage is great but I got tired of putting in radiators. I have 3 weeks on my Fluidyne. I also have a brand new, in box, Mishimoto for $100, man. trans. NO...

    ICS and TPS question

    Grady, Very good observations! You must have met me before, you have me pegged! :) I'm always in a rush making more than one change. Or, making big changes all at once. I figure I can always go back to the tune that worked before so I'm in a hurry to make progress. Or, at least I find out...

    ICS and TPS question

    HiYas Grady, I pulled about 12 degrees from everything below 20% load and less than 1500 RPM. That really helped. I'm solid on my drive and neutral idle airflow. They are easy to data log. TB airflow is not easy to data log if the engine won't run! What I did was to guess that the...

    ICS and TPS question

    Guys, thanks for the reply. My idle works fine now but the engineer in me always wants better. My '65 (A9S) always idles well. My '94 has always had a problem when the fan or A/C comes on. In CL, my ICS duty cycle is about 30% with stock idle spark tables, (20-25 degrees). But, when...

    ICS and TPS question

    Hi Tuners, If you disconnect your ICS, will your engine die? If yes, does it slowly die or do it as sson as your ICS disconnects? I am asking this as the refrences I have reviewed say to log your TB air flow this way. They also say that the engine should run with ICS disconnected. How...

    CBAZA Trends timing not following tables

    Update In my work, I'm an instrument and controls engineer, we have a saying that describes when something works, but looks like it doesn't ,because we don't really know how it is soppose to work. We say the equipment is "malfunctioning perfectly". With regards to the Tweecer, the problem was...

    CBAZA Trends timing not following tables

    Hi Grady, I think I am causing problems with my sig. My '65 Fastback,(A9S), sig car, runs great. Makes about 560HP and has been reliable for three years, except for some shuffling on occasion. The car I am talking about ihere is my '94 Vert. You may remember an earlier post "$600 Vert"...

    CBAZA Trends timing not following tables

    Grady, I didn't realize that closed loop operation didn't following the spark tables. My thinking was that the spark should be the lowest of the three tables, all the time. I guess thats not right. Comparing the three tables, to the logs, clearly shows they don't follow the table. That was...

    Try now. The data log should be good.

    CBAZA Trends timing not following tables

    More information: The tune I posted yielded 45 degrees timing at high loads! Talk about ping! For my EEC, it does not seem to follow the spark base table at all and is certainly not taking the lowest spark of the three tables. Thanks, Eric

    Grady, BDLN table set to all cells 55 Wes, not sure how to post tune and data log. Files won't attach normally. Eric

    CBAZA Trends timing not following tables

    Hi Tuners, I'm pulling my hair out, and I don't have much left! I am setting timing use base table, altitude and MBT table set to 55, all adders and retards zeroed out. Global adder=0, multiplier=1, load switch 0. I researched Gradys website, reviewed his tune, compared to mine and I can't...

    mishimoto rads, how are they holding up?

    I have had two develop tube leaks, in the same area. I'm not balming them as I think the problem may be mine. I can say, the sent the replacement out ASAP but it lasted 2months before developing the same leak. They get an "A" for warranty coverage. My car was hit in the front. I think I...

    new dyno #'s for the turbo 67 mustang

    "Where ya been Eric ? This on was a dynojet. The car made huge inprovements everytime it was leaned out. It will go way over 500 if let. The timiing is just a hint on the safe side, but we may spray it to add timing. More torque would be fun." Sorry if the question had been asked already...

    new dyno #'s for the turbo 67 mustang

    Good Job 10sec! Dynojet or Mustang dyno? I have been waiting for some more data to compare with my results. If you remember, I used ported out stock 289 CI manifolds. My numbers seemed high on torque, low on HP compared to typical. I was 454RWHP/510Ft-lbs at 8.5 PSI on a Mustang dyno. I...

    Calculating injector timing

    "When i did my first injector timing calculations based on EEC Analyzer "original" settings Initial Distributor Timing" = 10 ( i now know it sould be 0)" Nope, use -10 in the EEC. -10 means the intial timing is 10 BTDC. 10 means 10 ATDC. Using the EEC timing cals will yield better milage...

    Chasing idle issue may be a MAF problem?

    Thanks for the input, Grady. Just to make sure we are not misleading others, who are following this thread, I wanted to exspand a little more on MAF sensors. For a given air flow, if the sensor output is near 5 volts, there is nothing that can be done to reduce this voltage. You are right...
