LT1 PCM Tuning Tips Tricks for DIY Tuning I have some basics and tips Ive picked up as Ive tuned my own 1. Camaro Z2. 8. Much of it can be applied to other vehicles as well. This will be tailored to the LT1 engine, especially the 9. VE table tuning aspects will be even more helpful to 9. LT1s. After payment, the 2. PDF of these free online tips will be emailed to you. Tuner. Cat is your first step, the program I recommend to read your current PCM image, change its contents, and then reupload it to your PCM. It is a great program, also known as Computer Automotive Tuning Systems C. A. T. S., which allows the above things to be done, all for only 6. Youll also need an additional PCM file EE for the 9. LT1L9. 9 DA3 for the 9. LT1 F Body or DA2 for the 9. Y Body Corvette, which will cost you an additional 1. Tuner. Cat. Your other free option is to use EEHack for flashing and data logging, and Tuner. Pro RT plus the appropriate XDF EE or DA23 for your PCM to do the tune editing. Second, youll need the appropriate cable connector to go from your car to a computer. These can be bought from OBD Diagnostics, Inc. For a 9. 4, youll need the 1. OBDII style connector, but its still OBDI protocol. If you have a 9. PCM 3. PCMs are not flashed based. All together, youre looking at a starting price of at least 1. For 9. 6 LT1LS1 PCMs, you must purchase another program originally made by Tuner. Cat and now sold by JET, the Dynamic Spectrum Tuner DST, which is much more expensive 3. VINs Amazon usually has the best price. Third, get a logging program, that will allow you to see how your car is running.

Of course, youll also need a computer to run the program A laptop is ideal, but not necessary if you can put a desktop monitor close to your cars parking spot. But without a laptop, youll have no way to log your car while it is out on the road necessary for real life engine load and thus accurate spark timing knock feedback. There is no VIN or individual PCM restriction with Tuner. Cat, so you can tune multiple cars andor PCMs without having to pay any additional fees. However, it does not have definition file for OBDII cars 9. Its important to be sure that your vehicle and engine are mechanically sound before you begin tuning. Run some engine cleaner through your fuel tank, throttle body and intake manifold brake booster hose is a good entry for that. I recommend using Sea Foam for this. After doing so, check your fuel injectors, that they are all flowing freely not cloggeddirty and are not pulsing intermittently. Consider replacing your fuel filter, and verify your fuel pump is in good working order. Make sure all parts of the electrical and sensor system are in good condition, including spark plugs, plug and coil wires, coil, distributor Opti Spark for the LT1, ignition module, throttle position sensor TPS and IAC valve. If using a MAF sensor, gently clean its filaments with a cotton swab dipped in rubbing alcohol. Over time, dust and grit builds up on the filaments, which decreases sensor accuracy and leads to a rich combustion. You will also get the most consistency when tuning by leaving your MAF sensor stock, unported, with the screen intact. Consider replacing your oxygen O2 sensors. If your car has been running rich for awhile low MPG, excessive black soot under rear bumper, chances are the O2 sensors will need either cleaned or replaced. To clean, try brake cleaner. For replacements, I suggest using only ACDelco brand, as other brands have caused problems for some people. Newclean O2 sensors can make a huge difference in how well the PCM works the PCM will read richer than it is when the O2 sensors are fouled. Be sure there are no exhaust leaks anywhere before the oxygen sensors also check for vacuum leaks, around the throttle body, MAF sensor, and the intake manifold they commonly leak on these engines. If any of these things are in poor repair, they can cause the PCM to think the engine is running one way when it is not. A good tune will never be achieved if something mechanical is in need of fixing or replacing. Its also important to understand how the PCM works, and the terminology used when tuning. PCMECM powertrainengine control module, common terms for the computer that controls the fuel and spark delivery to modern engines, as well as their automatic transmissions. RPM revolutions per minute, used for engine speed. TDC top dead center, or the highest point the piston reaches inside its cylinder in the engine. Timing used for the timing of the firing of the spark plugs from the coil can be advanced fired further before the piston reaches TDC or retarded fired closer to or after the piston reaches TDCBLM block learn modifier fueling correctionSTermLTerm another name for BLM see above one is for long term fuel correction, the other for short term.

More power is generally made with richer AFRs less than 1. Vacuumk. Pa these are inversely proportional, meaning more vacuum equals lower k. Pa 1. 00k.

PE Mode power enrichment mode this is the PCMs modification for the car being at full or wide open throttle WOT. As more power is made at AFRs of less than 1. Download Pdf File. AFR, this mode allows the engine to run at a richer AFR when at WOTVE volumetric efficiency, describes how well the engine can receive incoming air for combustion so, for a given maximum of how much air could be ingested at a given point at normal atmospheric pressure 1.
