regular old m60 swap

[dasmanschaft012]

I have 1263 as well for purge valve.
I've tried multiple different resistor values on those ECU pins, and i haven't had any luck clearing it. I have an actual purge valve i guess i might just try to wire into the glovebox see if that works.

Compression tested today and she's still around 130-140. Was hoping driving it around knocked some carbon loose. Got a new maf and the only code I get now is 1263 for what I'm assuming is the lack of a carbon canister. Gonna leakdown test this weekend.

I have none of those problems lol.
Tune will fix my AFR problem however

I had a very similar problem with mine, swap the ecu would run well for a little while and then start playing up again. Thought it was bad ecu or chip. Tried all sorts of parts and test's.
Changed my coolant temp sensor for the ecu and boom, everything's smooth and nice again....may be an idea to check the sensor with another good one?

Hmmm that's pretty interesting. I never thought to check that out. As for now the problem has stopped, but I've only driven it for a few miles, so we shall see.

MarkD sucks

Crazy to think that I've known his name for almost a decade now, the chip works but the customer service wasnt anything to write home about

it's absolutely ridiculous that it took over a month to get to me.

i was having these exact problems. low idle, stalling after engine braking, poor acceleration in various rpm ranges, backfiring whilst off throttle. Turns out the auto ecu's have different maps causing manual swaps to run kind of funny, but my lightweight flywheel exacerbated the problem making it really obnoxious to drive. After a lot of googling i've found a lot of threads on 540's having the same issues after manual swaps, and discussions on the differences between the two ecu's

which problems did the chip fix, specifically?

This for me too

Got the chip installed yesterday. The car fucking rips, but it's absolutely ridiculous that it took over a month to get to me.

A month later. Still no chip, extremely dissapointed with my experience with markd.

I suggest SSSquid. Very responsive communications.

regular old m60 swap

Doing a little driving, still haven't done any poking around. car makes a fluttering whistle noise on acceleration, im assuming its a vacuum or exhaust leak.

Stiill waiting on my markd chip. I've emailed him a few times now to no avail....

[dothadance]

10$ says theyre all auto chips. you can replace just the eeprom chip in the ECU with a manual one, or a tuned chip.

Why fuck around, just get a SSSquid tune and know your ECU/chip are good.

Lol Waiting on my markd chip right now.
