What is your opinion is the best ECU if you are interested in tuning yourself or at least tweaking a tune?cool.gif

I was thinking the Link but otoh it's quite complex so maybe something older and more basic for a beginner?

For an ECR33.

Power fc is the best to learn on. Use paulrr33 power fcfaq. Read it a couple of times. Its the best resource fr power fc info. Totune though u need a wideband 02 sensor. 350$ and prefferably fc datalogit 400$. And then some like to use a pyrometer too which can be 300$ish

They are like hens teeth for the RB25DET though. What's the 2nd best alternative?

Definitely get a power fc, datalogit and a wideband if you want to start tuning. All I can tell you is it takes just hours to learn how to tune but years to master it.

I'm not convinced there is such a thing as a master tuner. Sure, people will get better at it but at the end of the day its just a brave sod who reads a bunch of clues required to reach an end point and takes the necessary steps to reach said end point. If they are lucky and the end point set by whoever put the car together is a good one then the tuner stands to achieve God status when in fact they just did what they had to do. If the end point was always going to be a bad one, then their name can easily become mud for just providing an inevitable result.

There will obviously be people with varying degrees of ability to read the clues and take the best possible steps to be able reach the inevitable - but so long as you are reading clues and realistically taking guesses (however educated) you're never the master of the situation :) If someone deems themselves a master, I'd personally approach with caution... as I'd say from my experience with this so far its a game where the old "The more you know, the more you know you don't know" thing runs very true.

You stand to learn a lot very quickly, so pay attention.

Just my opinion, of course.

Self learn isnt just plug it in and it starts tuning its self. U need to know what AFR the engine needs at each load point at different rpms etc etc.

Plus u need a wideband 02 sensor connected to the laptop or auxillery input of the ecu.

Power fcs are the best to learn on because they have a knock reading. This is a tuners best friend.

My opinion is vipec. Pretty easy to learn and the help file is actually very informative. I find myself refering to it all the time if I need furter information on a certain parameter.

IMO there is a bit of a dogma when it comes to guys being hung up on the power fc. The newer ecu's have a lot more going for them. Just because you know a product inside out doesn't mean it's the best thing out there.... Just means it's the best thing for you.

+1 on the Vipec.

I used to have a Microtech and found that an absolute pain in the ass to try and learn how to tune on. I ended up selling it and buying a Vipec and now I do my own tuning.

The layout of it all and ease of finding settings makes it a pleasure.

i'd say the power fc is probably the easiest to learn and get running properly as you really only need to tweak the basemap a bit and setting up afm's and injectors is a piece of cake.

not sure about everyone else but at first the simplicity of the power fc is great, its easy to get a hang of, but after a while i found myself getting very frustrated at how basic some parts of it are. my main gripe with it is the way it handles ignition timing and to some extent interpolation. only being able to increase or decrease timing by whole degrees can be frustrating when trying to find the limit (yes i know most people would have 2-3 degrees safety margin but not everyone wants that) and it also seams to round up when interpolating, which in certain spots is a right pain in the ass. i've also seen it favour the last cell it was in when interpolating, for example as your approaching peak torque and each cell has a fair bit less timing than the last it doesnt seam to always interpolate evenly to give a nice steady drop in timing, which can be a problem. say your half way between 1 cell which has 20 degrees of timing and another with 16, the result for that point should be 18, a lot of the time i see 19 and 20.

i find myself wanting a vipec or similar more and more everytime i play with the power fc

microtech is the easiest and quickest cause its as simple as a calculator :P BUT MY SUGGESTION is --->

Powerfc as its the safest to self tune as you have the safety net of the knock monitor system so you can learn the ins and outs of timing.

ecu's like vipec microtec haltech etc require you to know what an engine can safely take and to tune it properly you should use some kind of listening device.

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
