2g 95 ecu dsmlink clicking relay

[crazycoot80]

I am having a very strange problem!! I fix aircraft electronic cuircuit boards for a living and am very good at soldering and what not. So I bought a DSMLink chip and installed it myself all solders were perfect and all connections were made.

Tripple checked all connections to both IC chips from the DSMLink chip with a Fluke multi-meter and all were good. Car warms up fine but dosent want to idle down then when its warmed up for like 20 min. it dies and relays start clicking under the dash then it wont fire back up till it sits for like 1+ hrs. and link conects fine also untill it dies. Then Link wont connect.

Car ran OK before Link install but would randomly drop 2 cylinders and had random miss sometimes. It would also pull like mad sometimes and like a dog other times.

Also car has a 6 bolt JDM swap.

Do you know for sure the ecu is a 2g ecu and not a 1g ecu? If it's a 1g ecu, replace the 3 capacitors on the board if you haven't already. They cause problems similar to what you are describing.

this sounds like a low voltage to the ecu problem.when it idles down, it seems to make less voltage and power starts to click on and off to the ecu,untill it shuts down and you have to wait for it to reset itself before the car starts back up.
what is your idle set at?mine did the same thing untill i raised the idle just a touch,maybe 50 rpm.check the basics first and make sure it isnt a charging/ battery issue.
sounds like your pretty mean with a fluke,so should be easy for you to check voltage to the ecu ect and get it fixed.

Did you solder a socket to the ECU and then install the chip? Or did you solder the chip directly to the circuit board where the stock EPROM was (after removing it)?

He would need the adapter board if it was a 1g ECU. It's a slim possibility, but I doubt this is his issue.
