Jay Rojakman Posted February 14, 2021 Report Posted February 14, 2021 Need some help here. Recently plug in GTTLINK pnp ecu to ER34. Once start, the lights is on on both TCS and SLIP. I replaced the ecu with working ecu and also Power FC, both lights is off. Reinstall bank Link ecu and its on. only modification on wiring i did is replacing boost sensor with link 3 bar map sensor. others remained untouched. What could it be possible to have this issue?

DevLeague Posted September 26, 2021 Report Posted September 26, 2021 Same boat here. Going in for a tune tomorrow maybe it's just a setting or such. My car works fine with factory ecu and once I swapped over they both lit up. Quote
Adamw Posted September 26, 2021 Report Posted September 26, 2021 The TCS and slip will no longer function with an aftermarket ECU. Most users remover the bulb. Quote
DevLeague Posted September 28, 2021 Report Posted September 28, 2021 Thanks mind is at ease. All tuned now and running well. Few more upgrades to get to where it needs to be. Quote
