Oct 07, 2015 · They bench test them so you know they are correct. The LT1 maf is fine too, I ran that once. Just stick a cone open element airfilter on it or the stock maf. Kirban sells a bracket too so the filter/hose doesn't ram into the alternator on acceleration. Did that once, in fact it cut the maf hose in half and shut my engine down.

This harness is intended to convert from the LT1 style 3-wire MAP sensor to the LT4 4-wire TMAP. The harness connects to the MAF and breaks out the IAT wire in addition to adapting the MAP sensor connection. Combine this with the DSX Evap Extension Harness for a complete plug and play LT4 blower conversion. The LT4 M Mass Air Flow Sensor Facts. Most of the C4 Corvettes used a MAF (Mass Air Flow) sensor to determine how much air is being pulled into the intake manifold. The exceptions are the 1984 Corvette that used a speed density system--a sort of predictive method of measurement---and the 1990 through 1993 C4 models which were also speed density based. Available now for the Gen 5 LT1, our sensor package includes a properly sized MAF air tube, MAF sensor, and front O2 sensors.

These replace the factory MAF (Mass Air Flow) ends that are restrictive and have a screen on them for high flow. On the LT1 the MAP sensor is used to determine spark advance as well as some diagnostics. There is a lookup table that is RPM versus MAP KPA for spark advance. When the MAF sensor has a problem, the LT1 can also run in speed density, which uses the MAP to calculate airflow and thus determine the necessary fuel. AC Delco 3" LT1 Mass Air Flow Sensor These are to be used with the Turbo Buick MAF Translators, as well as the DSM Translators.

The "B" body cars has iron heads instead of aluminum and the engine was rated at 265 bhp. First year of computer controlled automatic transmission (4L60E). And of course after you are done with the maf table calibration to complete the tuning process you will need to set the high rpm disable back to 4,000 or wherever you would rather the ecu start to prefer the maf sensor over the map sensor and then you will want to turn back on the COT, DFCO, and PE. Before we jump into the diagnostic, let's take a look at how the MAF sensor works so the procedure makes sense to you. Basically, the MAF sensor measures the amount of air flowing into the engine through the air cleaner assembly, which contains the air filter and connects to the throttle body. AC Delco 3" LT1 Mass Air Flow Sensor These are to be used with the Turbo Buick MAF Translators, as well as the DSM Translators.

Delphi OE technology validated to match the vehicle applications; manufactured to meet or exceed OE requirements. The MAF sensor is located between the airfilter housing and the corrigated tube going to the throttle body. The MAP sensor would be a little square box with an electrical connection and a vacuum line running into the bottom of it and is usually mounted to the rear of the plenum or the firewall. On the LT1 the MAP sensor is used to determine spark advance as well as some diagnostics. There is a lookup table that is RPM versus MAP KPA for spark advance. When the MAF sensor has a problem, the LT1 can also run in speed density, which uses the MAP to calculate airflow and thus determine the necessary fuel.
