What is the ECU pinout for the S15 SR20DET?
Today we are looking at the ECU PINOUT for the S14 and S15 SR20DET Blacktop engine. This version of the SR20 was the first to utilize the VCT timing mechanism now common in Nissan engines like the VQ35DE. The last SR20DET also received heavy modifications and changes to the intake manifold and throttle body.
How many maps does a SR20 ECU hold?
The S13 SR20 ecu is 256 kbits, so the minimum size chips to be used would be twin 128 kbit chips, and these would hold only 1 map. Two 256 kbit chips will give a total of 512 kbit, and therefore will hold two maps. Two 512 kbit chips will collectively give 1024 kbit and hold 4 maps.
What kind of engine does the SR20DET S15 have?
The same ball bearing T38 Disco Potato turbo, along with an upgraded 480cc high impedence injectors helped this SR put down 247hp @ 6400RPM. For all SR20DET engines from 1999-2002 found in the S15, we’ve got the complete ECU pinout and wiring diagram for your engine swap or ECU wiring.
