cpu codes
hey, just wondering if there is anywhere to look up specs for all of the different engine cpu codes including jdm
|
btw, by codes I mean the one on the outside of the cpu itself not error codes.
|
Kevin put the info on his web site last year.
www.rotaryresurrection.com Go to the TECH section - ECU Applications list |
awesome thanks
|
I just took a look at that link, it is helpful but I am looking for specific specs. and differences between each cpu, which I'm guessing might be hard or impossible to find. I know the original manufacturers and aftermarket chip vendors like to keep them secret.
|
The shops that have reverse engineered the stock ECU do need to recoup their R&D.
The easier way is to go to a stand-alone. |
The CPU is the body computer and has no error codes other than buzzers.
The ECU is the engine computer. |
cpu, ecu, pcm, ecm..... all the manufacturers call it something different my haynes manual calls it a cpu and calls the other one a chassis control module

So since the car has a CPU and a ECU, how are we to figure out just what your talking about if you don't define better what your talking about? All Haynes manuals should be burnt or turned into beer coasters. That's all they're good for. |

What do the abbreviations I see in the 2nd gen section mean? AAS = Auto Adjusting suspension ACV = Air Control Valve AFM = Air Flow Meter (also see MAF) A-spec = North American Spec ATF = Automatic transmission fluid Auto = Automatic transmission AWS = Accelerated Warm-Up System BAC = Bypass Air Control CAS = Crank Angle Sensor CPU = Central Processing Unit (the Body computer) DEI = Dynamic Effect Intake (found on 84 and later 13B engines) DMM = Digital Multi-Meter (required for most electrical testing on cars) DTSS = Dynamic tracking suspension system (found on all 2nd gen RX-7s) ECU = Emissions Control Unit (also called Engine Control unit) EFI = Electronic Fuel Injection EGI = Electronic Gasoline Injection EMS = Engine Management System (aftermarket engine computer) FB = 1st gen RX-7 81-85 production FC = 2nd gen RX-7 86-92 production FC3C = 2nd gen RX-7 convertible FC3S = 2nd gen RX-7 Coupe FCD = Fuel Cut defender (aftermarket- used only on Turbos with modifed exhaust and stock ECU) FD = 3rd gen RX-7 FI = Fuel Injection FMIC = Front Mount Intercooler GS = Sporty Model (in CAN) GT = Sporty Model with Turbo GT Limited = fully loaded every option turbo model. GTU = Sporty model in 88, base model in 89-90 (in USA) GTUs = Sporty model in 89-90 (in USA) GX = Luxury Coupe model (in CAN) GXL = Top line Luxury non turbo model J-Spec = Japanese/NZ/AUS spec model LSD = Limited Slip Differential (sometimes incorrectly called Posi or Positraction which is GM's in-house brand name for their Limited Slip Differential) MAF = Mass Air Flow sensor MOP = Metering Oil Pump. Oil Metering Pump as called in the service manual. (also see OMP) NA = 1st gen Miata NA = Normally aspirated/ Non turbo N/A = Normally aspirated/ Non turbo NB = 2nd gen Miata OE = Original Equipment OEM = Original Equipment Manufacture OMP = Oil Metering pump PD = Pulsation Dampener PS = Power steering PW = Power windows SA = 1st gen RX-7 79-80 production Savanna = The name the 1st and 2nd gen RX-7 was sold under in Japan. SE = Base model in the USA in 87.5-88 Series 1 / S1 = 1979-1980 RX-7 models Series 2 / S2 = 1981-1983 RX-7 models Series 3 / S3 = 1984-1985 RX-7 models Series 4 / S4 = 1986-1988 RX-7 models Series 5 / S5 = 1989-1992 RX-7 models Series 6 / S6 = 1992-1995 RX-7 models Sport = 86-87 Sporty model (in USA also see GS) TB = Throttle Body TBM = Throttle body modification TID = Turbo Intake Duct TMIC = Top Mount InterCooler (factory style) TPS = Throttle position sensor TII = Turbo model T2 = Turbo model VDI = Variable Dynamic Intake WOT = Wide Open Throttle 6PI = 6 Port Induction the auxiliary ports, or the not so correct term - 5th/6th ports 13B = Normally aspirated/ Non turbo, 2 rotor, rotary engine. 13BT = Turbo charged, 2 rotor, rotary engine 13B-RE = J-spec Cosmo twin turbo, 2 rotor, rotary engine. 13B-REW = FD twin turbo, 2 rotor, rotary engine. 20B = J-spec Cosmo three rotor, rotary engine. |
I agree about the haynes manuals and I was just trying to say that it was an honest mistake I'm used to working on many different cars and they all call it something different. Also I don't care what your FAQ says it's not the be all, end all of general automative abbreviations and acronyms!
