You understand that because you're dealing OBD1 the ECM mem cal's are tuned to the specific vehicle powertrain the mem-cal is plugged into for particular vehicles ECM. If one is attempting to do custom chip mods you can't just use a program such as TunerPro to alter the mem-cal, you have to burn a new eeprom blank chip (27C256) to fit into the chip housing that plugs into the mem-cal slot.  To burn the chip you will need the physical Moates chip burner, a laptop with the Moates software on it to read the existing mem-cal, extract that BIn file, then you have to write the new BIN program with the Moates software & then command the burn of the new blank chip. To be honest one usually doesn't get it right the 1st time. Here is the list of GM OBD1 ECMs & the accompanying MEM-CAL ID's. Yours will the 1227727. Your engine code is *T*,  the mem-cal will be for either auto or man trans. Your mem-cal has a sticker attached to the mem-cal, pull the ECM inspection cover, the mem-cal is right below the cover for easy access. The ECM is easy to recognize, open the hood, in front of right side shock tower under the plastic cover, bolted to the shock tower. https://pcmhacking.net/ludis/p4xref.html#1227727

Thanks. I should have worded that better. The 1227730 is not confirmed. I only listed it because I found TunerPro definitions that referenced the 1227727/1227730 family. I haven't physically verified the ECM service number yet. Before I pull the ECM, can someone confirm the factory ECM service number and MEM-CAL for a stock 1990 Cutlass Supreme 3.1 LH0 W-body? Also If the factory ECM is 1227727, which TunerPro ADX and XDF are you using for a stock 1990 LH0?

That’s the correct dipstick for my 94 z34. Same one I ordered by vin from the dealer. When I change the oil it takes 6qts on the money.

Do I have the correct dipstick for a 1995 Oldsmobile Cutlass Supreme with the 3.4l DOHC engine? Photos below. The owner's manual states 5.5 quarts of oil when doing an oil and filter change. I change the oil and filter, run the engine for a few minutes, let it sit for about 5 or 10 minutes, then check the dipstick and it shows the oil between the high and low marks.  

Where'd you get  a *730* ecm from? That's an all metal cased unit, it was not put into the W body cars. There's no way to mount it at all. The proper ecm for your car would be the 1227727 ecm. Seeing as you have the incorrect ecm you more than likely do not have the correct memcal chip as well.
