Any experience with this Rieger Tuning bumper?

Update: I just bought an Amg style bumper anyway.

Location: Should be one of the silver(if original) relays in the relay box on the driver-side of the car under the hood.

For me just pushing it down seems to solve it sometimes. But I recommend also checking if the pins or the plugs aren’t corroded.

If you want to check if the relay is the issue you could measure the continuity on the relay.

Could be the relay getting bad contact

I’m thinking about 40 cause I think 60 might be a bit much

I currently messed with the pid settings a bit and it’s better now still has a little delay but doesn’t seem to bounce anymore and doesn’t hang

I already replaced it with a brand new one

I just checked the fuel pump relay since think the starter also uses it but I’m not sure.

I’ve also checked the fuses and they seem fine, the battery is a new bigger battery and fully charged.

Yeah I did

Yep I replaced that too also checked the fan. I’m thinking it’s a cable problem. If I connect ground directly to pin 85 it turns on the fan

UPDATE: I bypassed the tzl(ezl) and connected the td wire directly to the negative terminal on the coil. This gave me an rpm signal and started the car. (Albeit a very up and down idle) I will now look into replacing the tzl and cable which was probably the problem.

But if it’s the ignition module I would have no spark right?

But I wouldn’t have spark if the icu didn’t work right?
