    ECMlink After upgrading injectors, do you also have to upgrade the fuel pump right away?

    I would change the pump as i suspect you will turn the car up. The larger 450 and 525 pumps have there place. We like them but yes they have there drawbacks, as i recall the 255 walbro's we have used in the past max'd out around 425-440whp on e85 on the dyno. So something a little larger would...

    We never have had issues with arc2 box's either honestly, one is on a 6466 10:1 car stock coils, ngk 7mm stock wires at 37psi right now. Myself and a buddy both use them with 300m coil on plug and have been happy too. I have noticed some low rpm misses like others have said i suppose but nothing...

    ECMlink Please review logs TUNING GURUS

    Like some have said when you hit 100VE you know your injector settings are correct and fuel system. So then making it hit the target air fuel with VE table shows that the ecu's calculation of airflow and fuel it adds is correct. No trickery going on or fooling it just it being correct.

    ECMlink Help with tuning SD. What next?

    Very low timing. The air fuel ratio was fine but technically lean 1 point from your target. I would adjust the DA table to reflect the air fuel target you want then adjust the SD table to hit it. Looking at SD table i am going to guess that will get you close too 100 ve at wide open and confirm...

    2G EVO Oil Squirters in a 2G

    We always delete them. My own motor has a slit machined in rod so oil in theory will squirt out past rod bearing and up towards piston.

    Street Build Resurrection of the Red 90 Talon

    We always shoot for .002 main and little larger on rods. Most rods require .002 minimum, Manley I beams do as I recall. These clearances with 20w50 work very well. We like the Weisco HD pistons and also run 10:1 on e85 cars. Don’t forget to use a stretch gauge on rod bolts. The regular arp rod...

    2G Best daily wheel size

    There is some factors. My 2gb gsx has 17x9 +35 with 245/40/17 and does not rub, but not All 245 tires are same width so some maybe would rub. It’s I think as large as you can go on my 1.75in drop and still be flush with body and clear.

    When belt is removed at TDC the cam always moves a little. Line everything back up and you will be fine.

    Personally we use only 6 bolts or 98+ split thrust 7 bolts. The late blocks use the thrust washers similar to the evo vs saddle thrust they used on the early 7 bolt blocks.

    ECMlink New SD setup Hoping to have some "wiseman" check my logs

    Looks like a 1g timing table? That will end up to aggressive for what you are trying to do. For the injector sizing with SD i like to set the speed density table to 100% ve 5-5500rpm is likely where yours would hit that. Then adjust global fuel so it lines up target AF and wide band at that...

    Resolved How to make BOV flutter

    Let off the throttle slow will do this, but as many have said it is hard on the turbo and it causes the compressed air to slam back into the compressor wheel.

    ECMlink boost breakup!!!! I got log and money

    You are very rich. Your Sd table is over inflated badly. Set to 100 VE at 5-5500 rpm. Then set global so wide band matches your target air fuel at that rpm.

    Who is going to the Shootout in OCTOBER?

    I was at the shootout this year. I started going in the early 2010's. It still was great to see many familiar faces. I ended up tuning a few cars at the hotel seems i do every year. Sadly the car we had ready for it broke and we did not get it ready in time, we still came to help support the...

    General What do these plugs tell you.

    Looks a little soft on timing. Best way is to fire motor, do a pull, usually 3rd to redline, shut the car off and pull and read them right there.

    PTE 6466 vs Xona 9569S

    Interested also. I tune a local car on a 6466 .82 t3. Spool to flow is extremely good. I was considering it or a xona for my car when I dump the 62mm hx40.

    1G 1g tob noise & rpm drop - crankwalk

    Interesting, in my 14 years of building dsms I have only ever seen 1 crankwalk. This car also had clutch adjusted wrong so kept pressure on TOB so I assumed that is what caused it. All the motors I have built end up around .0025-.005 when I check crank play. I also always anytime a girdle or ARP...

    ECMlink InjBatteryAdj vs global deadtime or deadtime offset field

    I still prefer to use INJ bat adjust, to each there own. You can take what ever you have in dead time and then apply that to INJ bat adjust to end up with same result, as said above starting you need cranking fuel adjust and if above idle rpm then you are looking at SD or maf comp. All this...

    When I have a sheet to look at I normally use that data for inj bat adjust then fine tune it with dead time. Either way ends up with same result.

    I have not used a XTD in a few years. The last one i came across 5+ years ago was a 6 puck sprung i think and the car ripped the rivets out on the clutch disc on launch. Myself love the act 2600/ puck. Have been using these clutches for years.

    2G Questions regarding 1g rear axles in a 2g.

    You need the outer cup that goes into the hub? I think the outer is the same for all 2g, the Inner that goes into the diff its self is sorter on the non LSD vs LSD and does not interchange.

    ECMlink InjBatteryAdj vs global deadtime or deadtime offset field

    It does the same thing as dead time accept applies different amounts based off voltage vs dead time that is applied at any voltage. What ever your dead time value is then is added or subtracted from the injbat adjust table. When you buy injectors and they have a sheet you can plug those values...

    ECMlink Goes lean and breaks up around 4k

    Your tune does not look good. First zero out timing sliders. Use direct access table to make timing changes. Second use the max octane table to set target air fuel ratio for open loop. Zero out the fuel sliders and use maf comp to hit target. Using the sliders and DA tables is not a great idea...

    ECMlink Another new to SD help thread. 2g

    Even without a sheet you will be able to figure out injector settings. Hit 100VE that’s global, then use SD table to set air flow per rev, then use dead time or inj bat adjust to get fuel trims correct. A data sheet does make it easier but it’s doable without.

    ECMlink Target AFR maxoct table

    I have tried this years ago just to see what happens. I almost suspect the ecu always targets 14.7 unless in open loop as i never got any results other then ECU trying to hit 14.7.

    ECMlink DSMLink reporting ECT 300* Is ECU fried?

    I would see if ecm link can repair it. We have sent ecu's to them before with suspected issues and they always have treated us great. Yes if coolant temp is reading wrong it will cause car to not start or barely run.

    ECMlink Another new to SD help thread. 2g

    Global has to be off looking at your VE table. For the idle air flow per rev depending on cams and idle rpm that number can change. .25-.35 for reference GSC s3 at 1100rpm seem to like being around .30-.32 from my experience. Normally VE at idle to get air flow per rev inline will be mid 40's to...

    ECMlink Possibe PK?

    You can also "read" a plug to confirm if knock is real or not, but easiest way is to dump some race gas in. First make sure knock sensor is not oozing though.

    ECMlink VE Dropping Off Fast 16g WOT Log

    That small turbo will drop off quite a lot by higher rpms. That's why many on e85 with those size chargers run quite a lot of timing up top because of the VE dropping off, As i recall i am running 13 deg up top on my 10:1 e85 car on a 62mm at 35psi. My VE only drops to low 90's but again i have...

    I ran the hks catback on my car sense 2009. Granted it did not see winter but was still in good shape. Now all that's left is the muffler as i built it all true 3in now. Mine was 2.5 from down pipe then 3in after a resonator.

    2G ACL main bearings don't fit

    I personally have only seen 98/99 aka W or X vin blocks as split thrusts. But you could possibly run into a 97 car with a split thrust maybe. I always look at vin on the block to tell what it is and not look at year of the car. Way to many times i have seen XX year have a different year motor...

    1G Popping the oil cap. What could it be!?

    Leak down test will tell a better story. I see you said above you did one but only at 15psi was 20% leakage? Should be done at a lot higher psi then that.

    FP Red or HX-40 fix

    I think to many forget when on pump gas exhaust housing become a major factor. T3 hx40 is a great option. I currently am using a t3 hx40 in .82 housing with 62mm compressor wheel. I lost some spool in trade for potential air flow. I see 30psi by 5,100rpm and at 29psi have logged 57lb/min. I have...

    ECMlink Need a hand dialing in tune on E85

    Need a wide band reading. The tune does not look to hot to me. The only time sliders should be used i have found is at the track to make quick changes in between passes. Then when you get a chance port the changes over to DA tables.

    General Timing examples on a 90 lb/min plus car???

    Would need to know compression ratio. Reading plugs can really help finding out what the motor wants. My 10:1 motor as been above 70lb/min and i think i started at 8-9 degrees up top and worked up to 12-13 degrees. That much air flow would be best to use a dyno and read plugs to find what it wants.

    General Tuning options?

    I also have remote tuned a few cars. It requires a owner that is mechanically savy and knows the car is ready. You wont get every last HP out of it but is always a good option.

    When you are targeting a AF target and car is off on wide band then the airflow calculations are off. When they are way off to make it hit then that means injectors are set incorrectly.
