No Post start

Recommended Posts

Hello and regards from Germany!

I have a big problem with my Subaru GT MY97 and the Link G4 Plug In ECU.

My Engine is a EJ20T from the 1th Legacy Generation. The heads are ported. The Exhaust is a 4-2-1 EL Header with a 3" catless Downpipe. Turbo is a ported TD04. Injectors are stock on 36psi fuel pressure. 4 space crank trigger + 1 tooth on the camwheel


MainCode Firmware Version 4.8.1

BootCode Firmware Version 1.4

Main Board Revision 1.2

ECU Type Link G4 Strom TopBoard

ECU Serial Number 3722

LinkID 8001


All Triggers and sensors works fine . After 3 week cranking and 900€ for a stronger ignition system if found in the rumtime values and in the logger the problem.

The Crank enrichment doesent lean up and the post start enrichment doesent start over 400 RPM.

the normal cranking speed is 180-200 RPM.

See the Log in the attachment


Whats the standard firmware for this ECU and how can i fix the problem. the Engine doesent run with this ecu

Yes! I have change to multitoothwheel with 4 spaces on crank and 1 Pin on camshaft. It works fine and gives a clear RPM Signal.

I´ve found the post start problem. the crank enrichment hold te blockend the post start activation.

The standart wrx V3-4 map is too rich for my engine. I´ve try to lean down the map, but the engine does not start over 584 (max.).

Next try will be to pull the car with a other car for a high rpm start!
