Hey guys just wondering if you can shed some light, i've got 2 engine codes, p1602 - serial communication error with TCU, and*P0600 HYUNDAI - Serial Communication Link Malfunction
Now, I have a 2004 Tiburon 2.0L Automatic, 70,000 km, so heres the story, i recently swapped my stock manifold to obx 4-2-1 headers, i have a 2.5" midpipe with a magnaflow high flow cat, and then an ark dt-s v2, ( i don't think the problem is related to this) *now i also installed a multigauge recently and in the process i blew the fuse thats in the fuse holder, (by splicing into the red wire from the oem radio harness with an x-acto knife) the one that connects to pin 6 of the multigauge and supplies the battery voltage to it. *Now i dont think this is normal or atleast i dont think it was like this before, but when i turn off the car, and remove the key i can still roll up and down the driver and passenger window, until i open and close the door then i cant anymore, now its giving me a little bit of trouble, when in town driving at slow speeds, stoping, going, or at constant speeds 40 km sometimes its downshifting and then shifting back up shortly after, sometimes if i dont let off the gas it wont shift up, on the highway at 100kmh (60mph) my rpms are running at almost 3000 when they used to run at about 2600, and sometimes i get a little sputter where it'll rev up about 200 rpm for about 1 second and go back to around 3000, sometimes if i floor it, it just gradually accelerates and shifts at about 4500 and 4000 rpm as opposed to it normally redlining to 6500, but sometimes it will actually accelerate properly, wondering if someone would happen to know what the problem is and if its fuse related, also i had to extend my o2 sensors for the new exhaust (headers and cat) i did so by soldering longer wires to the normal wires and wrapped in a heat resistant casing, (dont think i due to o2 sensors)
Thanks everyone
