On another note thought this was interesting as describes the same weird lean condition with the stock ecu I was facing.
https://www.mr2oc.com/61-3sgte-turbo/14 ... boost.html

Maybe it is meant to be like that? Which means the cut that I was seeing could be either boost or knock related but not entirely sure which. Once I have the J&S connected I might see if it is because of knock or something else. I am 100% it's not overboosting as my boost gauge is accurate and I have set the EBC to boost cut at 17psi.

LINK, Haltech and MOTEC are the better ones for Japanese cars. They tend to be more well known and do a lot of advancements with their products. There are plenty of others out there but some are older and lower tech than what these manufactures offer. LINK has some good tech but the plug ins for the MR2 are getting old, not that the cars are getting newer. Software is still updated and you can add to them. Or go full wire in.

Yeah with more modern ECUs you can get nicer features like bluetooth connectivity for display outputs etc. I'm happy with the Power FC however as it does everything I need it to do. Know it's old tech but it does the job absolutely fine and if anything it is kinda neat having period correct tech - maybe one day that will mean something! :lol:

Anyway I just can't justify changing ECUs when I have a tuned PFC already and which has no problems. Starting from scratch maybe I would have gone a different way but honestly you aren't really losing much.

I'm battling with phantom knock now which pulls back timing by 1-5deg in those zones where I'm trying to make power which is very unhelpful. It can be turned it off in program but unsure what is real and what is not.

After speaking with a local Tuner he configures all the EMS systems conservatively and then turns off knock control. I'm starting to come to the same conclusion.

When I was co-driving for my brother in his Starlet with a twincam Suzuki in it, we had a Knocklink fitted that kept lighting up. Finally tracked it down to a stone between the sump and the sumpguard, which when removed, halved the times it was coming on. Then we found a loose/broken engine mount so that could also be something to check. There wasn't any issue with the motor itself.
See ya

Well I took the girlfriends DSLR and took a few pictures of the car. I am by no means any good at photo taking but it was fun to learn what angles worked and didn't etc.

Still might be dropping the engine next month in prep for the nationals! Really keen to but also don't want to rush and miss it completely. Hard choice as would rather have the cambelt and HFH etc done before a long trip. But hey it should be fine, fingers crossed :D

Well, I got around to pulling the engine to do several things:
Fuel Pump
Timing belt
Water Pump
Hoses From Hell
Oil Pump Seals
Crank Seal
Rear Main Seal
Cam Seals
Oil Pan Seals
Clutch
Slave

.... As you can see its a huge list. Here's a random assortment of pictures of the build so far. Wish i took more pictures but I was dirty and sore most of the time so refrained. Let me say that I have respect for anyone trying to do half of these jobs with the engine in the car. Would've been tough!

Turns out that my clutch was the ORIGINAL (surprised it has survived this long). Getting the flywheel skimmed today and some new flywheel bolts are on the way.
