    Cold start tuning for big injectors without glow plugs

    I started logging APP_D% along with APP% and remembered it reads about 17% higher than actual throttle. So that moves us up a couple rows in running torque table B1161. Where I pushed the 600RPM torque values up to 400Nm. See pic below. Then I rolled the cranking torque down to 400Nm and did a...

    Cold start tuning for big injectors without glow plugs

    One of the first adjustments after FP was bump low ECT idle to 820 room temp. Didn't seem to help as expected. That crank to run transfer seems to take place around 600 no matter what else changes. So not an idle overshoot issue, that would be to easy. Today I dropped it back to 760.

    Cold start tuning for big injectors without glow plugs

    Ok reviewed the pw and tq table settings, then implemented much of the advice above. As Dave mentioned, the PW values in lower mm3 rows/columns needed trimmed back a bit. I compared % subtracted from stock in Marks latest adjustment at higher mm3/MPa, and tapered up to it. Except in the low MPa...

    Cold start tuning for big injectors without glow plugs

    Yeah Mark had em running sweet, with 100 overs. Then sent me update based on flow rate of our new sticks to get things fired up. Along with plenty of helpful suggestions that's got em idling smooth. Soon as I get in the water he's going to seat of the pants rest if it. However this cold...

    Twins with Twins, Anyone?

    Thanks much. Will post testing updates over there shortly. For now, belt routing. Comments? LB7 tensioner with a smaller pully looks to be our winner..

    Cold start tuning for big injectors without glow plugs

    Ok thanks guys. I slashed the PW below 30 MPa, and I now see the direct correlation between cranking torque and our final injection amounts. By raising FP, your lowering PW automatically, but not by same factor as if you lower base mm3, or the requested Nm values. Cranking Tq / Nm = ECT @...

    Cold start tuning for big injectors without glow plugs

    That sounds reasonable. Removing the ECT multiple did seem to make it happier on cold restarts. What I observed is it starts fueling with a big PW in that 150-250rpm range, and adjusts downward as RPM and FP increase. About the time FP hits commanded (60) it will fire off but,, FP will...

    Yeah basically, They can be added, but it will be spending majority of life in +80F environment. Grid heater would have been good idea.... Sent from a russian troll farm using Tapatalk

    Cold start tuning for big injectors without glow plugs

    No cranking fuel table in LMM, just torque and timing. But I can possibly bring it up in another table, or add the second pilot back below X rpm. FP is making about 30MPa at 140Rpm, then it jumps to or past desired soon as it starts to fire off. Lift pump is on by starter relay and oil pres...

    Cold start tuning for big injectors without glow plugs

    Need some advice with cold starts / no glow plug setup tuning tips. Getting these puppies to fire up in a 50-60 deg shop first time is a real pain. With the 200% over sticks, I've finally got them firing up and holding a good idle on first try once they have a little heat in em. But when...

    How To: LMM OS - MAP Scaling

    Finally got chance to test these sensors running. Before installing on engine, I tested scale on bench with volt meter and air compressor. The sensors scale reads in atmospheric, not true pressure like a stock GM sensor. So you have to adjust map accordingly. But after a little playing around, I...

    Twins with Twins, Anyone?

    Yeah the owner just left. He swung by and helped out for a week on way to NY. Looks like I might head out to LA with it in Jan, and then ship out from there.

    LBZ Standalone Harness

    If you look at the EFIlive document on bench harness, it will give you the ECM and TCM pinout for hot wires ya need. Suggest you fuse and relay those hots from your key / switch, the starter directly to key. That's enough to get ya going on power and crabking. Then disable VATS in tune file...

    PPEI Next On The Chopping Block???

    In all fairness we did send them a canned letter... But they have a whole crew of assistants that do nothing but sit around and reply. Best you can hope for is they get enough emails on the subject that those helpers update them that it's a hot topic. I believe that's why lobbyists were...

    Front Crank Seal Remover/Installer

    Check the bypass valve just left of center of Crank. Have seen those leak. As stated above, front seals hardly ever ever leak. Unless you don't get them in correctly, then they will leak. Probably borrow the tool from someone who works at a dealership. Not common in real world. Sent from a...

    Twins with Twins, Anyone?

    For all the hours in em, gonna specify he test fires each one before checking the oil every day... One thing I've learned about solenoids on this project, torque is relative to starting position. The further down the bore that pin sets, the less pull ya have to start with. Reason I set em tight...
