HKS Turbo timer Type-O Issue

[ukrainekid]

So I recently installed a Brand new HKS Turbo Timer Type-0 into my s13 running an SR. Installed it using the HKS harness. So my issue which may sound odd is that when I accelerate enough to have my waste gate open the turbo timer Cycles off and on 1 time. happens every single time I put the car under load essentially. It returns to normal function and when I turn off the car it works as it should. This is extremely annoying to say the least due to its loud beep. Could this be a grounding issues. I grounded it to a location where I have other electronics and they are work fine. Or is it unit malfunction?

Any Thought?? LMK and thanks!!
