- Mods-EMS & Logging
ECMLink - with flex fuel updated firmware.
I sent my good shape no leaky capacitors 1990 original non-eprom ecu to ECM Tuning. They checked it out and did the eprom conversion.
GM Flex fuel sensor.
GM style Omni Power 4-bar MAP sensor for speed density.
Running speed density with no IAT sensor.
Gauges are: Autometer Tach, AEM Tru-Boost boost controller and gauge, AEM Wideband UEGO air/fuel gauge/controller, AEM oil pressure gauge.
3.3-30 VDC blue digital volt meter PM-123B from All Electronics
AEM 30-2400 Boost Control Solenoid.
Mitsu OEM narrow band O2 sensor for closed loop operation.
Fuel: Generally 40 to 50% ethanol in the summer, and 15 to 25% ethanol in the winter. The fuels I use are E85, and 92 octane ethanol free "boat" gas from a marina. I start adding only ethanol free gas to the tank in November, to reduce E% for the winter. Then in about late February I start adding E85 or E98 to the tank. I sort of level off at about E50 for my "summer fuel".
English Racing will sell you E98 for $6 per gallon if you bring your own tanks. Yup. Pretty nice.
Lucas English '91 tranny - Now broken (April 2019) - It was a stock rebuild, nothing fancy.
Tim Zimmer (TMZ Performance) is building a PPG dogbox transmission for it (summer of 2019). I don't want to blow up any more transmissions. It is getting too hard to find un-broken cores to start from. It's almost impossible now to build a good transmission without having an unbroken core to start from, because so many of the OEM parts are no longer available.
TMZ dogbox is finished and at English Racing (early October). My car is at ER (late October). ER done with install (late November).
Lucas English brought the car back to me January 7, 2020, on his gigantic truck.
I don't like that the shifts are so variable. Sometimes they are pretty nice. Sometimes they are so violent that it sounds like damage. I'd like to have a clutch that gives me more pedal travel near the floor in the disengaged region of the travel. More disengage. Maybe that would help.
Welded center diff (until April 2019).
Spooled center diff with PPG spool (after Oct 2019)
4-bolt LSD rear end from '93-94.
ACT MB1-XTSS clutch: w ACT organic street disk (until April 2019), w South Bend TMZ ceramic disc with 1" x 23 spline hub (after Oct 2019).
ACT streetlite flywheel.
Rebuilt driveshaft - with new OEM parts (done by Nick at PINA Motorsports in Kent Washington).
Hanger bearings modified by Lucas English to stiffen up the rubber parts with hot-melt plastic glue.
Shifter is an OEM 91+ that I bought new a few years ago, and new cables.
