1228747 C.A.T.S. vs TunerPro difference in ECM Mask / *.xdf file??????

Oh one other question, how do you define the COMM PORT for TunerProRT? I can use the same dongle as I did for winALDL, or do i have to get something else to make that work? I tried hooking this up over lunch to get some logs recorded but she didn't recognize the ECM when I plugged the laptop in. (sorry very new to all this)

Since we go through this all the time I made a sticky!

Ok so did as you suggested: "lower to 800 so it never happens, also the test1 and 2 spark advance are there, set them to 0 and also knock count to pass test to 0... " when I got home, burned the chip, plugged it in, and had to go out, so I didn't get a chance to do a set of logs with TunerPro RT yet (did get it to work, thanks for the sticky!!!). However I can say as I drove the caddy, that seemed (just from seat of the pants feel) to smooth it out some. I'll know more tomorrow and keep y'all posted. THANKS SO MUCH FOR ALL THE HELP!!!

Quick update here, First off got TunerPro connected and working loging, for about 3 mins or so then it sends my laptop into blue screen of death mode. It's done it all 6 times I tried, works great, logs show data in the tables, then BAM, death(will try re-istalling and check all the drivers, and I'm running Win7). Also, yesterday after work (still on base tune with ESC test "defeated" as suggested) warming the caddy back up in the parking lot at work to go home, she backfired 4 times. Then on the ride home felt underpowered, stumble-y and backfired again. I had only 2.8 gals left in the tank, so to be on the safe side i flashed the tune back to my baseline with ESC on (no change) and then filled her up with shell super. She got better within 5 mins, so I'm guessing there was some bad gas. I'm going to hit her with seafoam and put a new fuel filter in, just to be safe. If it doesn't go back to normal, I'll just drain the tank, thankfully the factory tank has a drain plug(got to love a 50's caddy,why every car doesn't have a bung & plug in the tank is beyond me).

Can't help with the blue screen, never had those issues. One guy recently had TP freeze quite often and changed USB ports and it went away. Must have been a bad/old/wore out USB port. Make sure you have all updates and drivers.

The fuel thing I've run into to often with old converted cars. Old tanks get crusy to begin with. Vented tanks and old fuel, worse if it's had any ethanol/E10 and it only lasts a few months and old tanks are vented so they get moisture which starts phase seperation of E fuel... water ends up on bottom of tank. I sat an old vehicle with drain plug at lowest point overnight, drained a half gallon of fuel into a glass jar, let it sit 30 minutes and could see the puddle of water in bottom. Fuel will start to look milky as well.

Do you run an external pump? I run a clear filter pre-pump and it will also show puddles or phase seperation goo. Then pump and a high pressure EFI filter after.

I tried switching USB ports, same story, alas, but I'll try my wife's laptop after I re-install all the usb drivers to be safe, this one is my work laptop so it could be my one of my "protection" settings causing issues with the program too. Luckily this tank (that I swapped in) is pristine, but the cap is vented so i'm sure there could be some moisture in there (and being a unbaffled, sumpless tank, I rarely let her get below the last 1/3, as i can lose all fuel to the pump if I turn too hard or go upill/accelerate too much). I'll do the sit and quick drain trick tomorrow too, good call. Yes I've got a external 255L/H walbro so that sounds like a good idea as well with the pre-filter. Once I recover from these minor setbacks and get an W/B O2 sensor hooked in I'll keep you all looped in on the progress. I also found a analog gauged W/B O2 setup from AEM yesterday, so that might be an option for me, seeing digital output on my dash is something I'm trying to avoid (or I could just use it to tune and unplug the gauge after as well... We'll see which way I go (next payday... )

Just a quick update, the tank is now cleaned and water free, I created my own fuel cap that seals (as I could not get one off the shelf that would work) so no more water/sand in the fuel tank :). Also, updated all the spark components that were still hold overs from the 89 2500 p/u. New coil, cap, rotor and wires, and also re-re-re-torqued the headers... She's back to normal again... I also ordered and received my AEM wideband AFR gauge and O2 sensor. However, the snow came at the same time, so now I'm stuck waiting for the meltdown to get that installed. More updates to come once I'm reading wideband.
