Many aftermarket ECU use two (or more) voltage regulators.
One is for "main power" ... for cpu, switches, and other..
Second is High precision / High accuracy ... for sensors, TPS, MAP, HALL or other "critical" components.

LD1117S33TR from mouser would save us a $1 here. What do we think about LD1117S33TR from mouser?
We already do most of this. The TLE8888 actually contains 5 regulators:JRD McLAREN wrote: ↑Thu Jun 27, 2019 9:41 pmMany aftermarket ECU use two (or more) voltage regulators.
Yes, I'm read TLE8888 pdf document ...
The option is called "Use fixed baro corr from MAP".JRD McLAREN wrote: ↑Tue Jul 09, 2019 7:06 pm.. on stopped engine, or when the ignition is powered on (and engine is stopped) .. Right ..??![]()
I am not comfortable with this style of instructions, please provide exact instructions if you have time to provide exact instructions. I can measure voltage at exact components if you give me exact part numbers like Rxx or Cxx or Qxx but I am not comfortable deciphering "resistor for pin Key" or "prereg ", these terms are confusing to me and the whole set of instructions is only confusing me and creates tension.
Both sides of R5 read 6.0v, same 6.0v on bottom side of R20.
