Wow, you went way farther that my post implied. First of all im not discrediting what you've done so far. It's not easy to learn tuning and the fact that it is running smoothly now shows that you have done well.

Second, What I was trying to tell you is that there is still more that can be done. Its not completely necessary but will improve on what you already have going. I was under the impression that you might like that.

Third, I was not taking back my statement. I adjusted it since you missed the point of what I was saying but it still applies to SD tuning. Yes, I do know that the maf table gets replaced with a VE map in the reflash version but the MAF sensor is not removed from the car because it is still used for IAT for SD to work since we do not have a dedicated IAT sensor. Since it is used for that there are still some compensation tables that are affected by it that should be adjusted. If you move the sensor to post intercooler then all tables pertaining to IAT must be changed to prevent weird conditions when ambient temps change because the stock tables are based on estimated post IC temps and you will now be reading actual temps.

Forth, calm down! Not every comment is an attack on you. I was being genuine when I said im glad its running good. With that said, if you don't handle criticism, positive or negative, very well you are gonna hate this forum (if you don't already). So relax and look for the advice in the post and not every minor detail if a generalized post. I posted based on the maps I could think of off the top of my head and since I have a 06 STi avcs came to mind. Yes, I know you don't have it, sorry I forgot that but don't miss everything else because of that.

Have fun with the car, I still would like to know how it turns out in the end.

Yes I know about the iat changes , I've tweaked it and it will get tweaked again when it gets moved post intercooler (as I put in my post )
All I ask is please credit folk with some intelligence ,
And maybe ask people what they have changed
Not tell them what they have not changed
What annoyed me was you put
(the fact is you have not changed this because blah blah )
Well it's now obviously not the fact is it
I don't want to leave this forum , like i said there are some very smart guys on here
But also I don't want to battle to prove what I have done , I don't need too
Same as I say please before telling me what I've done , ask me

Tony

There's some amazing guys on here so I'll just be reading there advice from now on ,
It's just not worth the hassle posting Any successful ventures , far too many negative folks for my liking
Very very sad

All the best and to those that want to mod/map there own car , go for it !

Here lies the problem. You're encouraging people to do it this way which is generally (9/10) very unsafe. It worked for you and thats grand, but alot of guys aren't gonna have the same fortune as you and by following your prodding, can end up with an expensive paperweight.

Perhaps there's more method to your madness than you've shared here. If you feel like anybody should be able to repeat your results, you should do a step by step write up with every key point and detail involved. But as a whole, what you did/doing is not advisable nor consistently repeatable.

Hi , I must make it clear what I've done is by no means the the safest and quickest method , I don't value my engine as much as some either , and it has not been done over a day or two , (weeks )and as part of my learning curve I've made use of probably every piece of available software and my det cans ,
And a lot of common sense
If you gonna go out and flash then thrash your car your gonna get trouble
but as proven (so far ) if you go steady and take a lot of time and care it can be done
, all I've done is what I've done for years but instead of turning screws , re jetting , advancing / retarding timing ,cam timing ,porting / gas flowing with conventional methods and tools , I've just applied to mapping , it's the same but cleaner and a lot more parameters to change
What did we do before wb 02 ?
All I can say maybe it's because I've tuned a lot of cars before so have a good idea ( maybe luck ) but it's hard to go wrong when 90% of the information and feedback is in front of you on a screen , then there's the mechanical signs to keep an eye out for
May I add I also built a BMW motor and turbo charged it ( good fun ) and went quite a lot into mega squirt with that project
Also raced bikes and used to build my own motors
So maybe I should revise what I said
If you have a very good in depth understanding of let's say conventional tuning yes give it a go

But if you don't know the principles of engine tuning then leave it to someone else

Is that fair enough

Tony

tony, you sound like a reasonable enough guy, so more power to you. cheers for tuning taking care of your own stuff! and i agree with you - with enough reading up on things, and approaching the process with respect, there's no reason why anyone else can't also be a tuner. people who are tuning right now, weren't born as tuners, they educated themselves to do it!

however, to comment on how people on this site are being nay-sayers and overly cautious about tuning... two things: 1) some of us have been around blown motors, and don't like seeing others go through the same thing; 2) you sort of answered your own question by mentioning that you don't care about your motor as much as everyone else does.

as for the mechanical indicators that people used to use before WB, EGT, etc. was they read the spark plugs. have you done that? it really won't give you as comprehensive a picture as modern electronics do, but it's possible to get a safe tune with det cans and reading plugs. it would just take extremely diligent plug reading (certain load/boost/rpm, then quick shut off the car, and read a plug... then do it again with a different load/boost/rpm...) and even so, you still wouldn't be getting as much information as modern electronics, but you *could* do it that way. so yes, it's doable, but a gauge is faster, better and easier. and depending on how many plugs you foul, it could even be cheaper. good luck man!

Congrats on tuning your own car, you are a special snowflake and so much smarter than everyone else who uses widebands and EGTs to confirm the changes they make on the rom. If you dont care about your motor rock on and keep tuning blind. My motor was a rather large investment so I and many others prefer to know exactly whats going on while tuning. A nice trick on the carberry SD rom is if you move your front factory O2 sensor behind the turbo it will read just like a wide band, I have tested it and both sensors overlap perfectly.

A car is always fastest right before it breaks, too much boost, too lean, excessive timing, ect.

I totally I understand a lot of guys have a lot of time and cash invested in there motors and are reluctant to tune themselves , theres no shame in that at all ,
as for the comment above , why sit and read it then ,and why comment , some have had negative views , some positive , but most have contributed with something
You my friend are one of those folk with nothing to say ,
And then whine at the mods to remove a thread about whining , doh ,
I take it your not exactly the sharpest tool in the box

Does reading plugs magically not work on these cars? What the hell did they do before?
