downtrail Posted October 23, 2014 Share Posted October 23, 2014 Normally tune ae once you can get it mapped to say 4-5k that's without stabbing the throttle once your happy with mapping upto there turn ae on and run around light load at say 2k and stab the throttle and watch the arf for leaning or richning and adjust ae points until afr stays in your range your going for takes a bit of farting around to get it smooth but once it is you may need to re adjust your ve table slightly to compensate cell changes etc 1 Quote Link to comment Share on other sites More sharing options...

Spencer Posted October 23, 2014 Share Posted October 23, 2014 Yea you have all sorts of fucked up airflow/fuel delivery shit going on no one here would have had to tune for. 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted October 23, 2014 Share Posted October 23, 2014 Lies. KPR said it I think. From memory it's the hottest burn so isnt any good for your engine. Quote Link to comment Share on other sites More sharing options...
Yowzer Posted October 24, 2014 Share Posted October 24, 2014 It's fine under light loads but under heavy you want richer as the fuel has a cooling effect in the cylinders, as well as offering a safety margain And other sciencey factors.

Testament Posted October 24, 2014 Share Posted October 24, 2014 yes stoich will be hottest because there is no extra fuel or air in there just chumming around taking up space that could be exothermically reacting - but I don't see why the higher temperature is a problem? higher temp = higher efficiency. its just a materials and heat management issue in other aspects but things should be up for that.

Spencer Posted October 24, 2014 Share Posted October 24, 2014 Its not going to hurt anything but yea you don't tune for it under load. The way Alex made that statement it was like he was told its a big no no, I mean if your cruise or idle is 14.7 who cares. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted October 24, 2014 Author Share Posted October 24, 2014 Yeah kpr saying that rings a bell. Yep rookie- slide throttles from what I read when I was trying with idea of making some are a bitch with the way air flows through them at light openings for road cars. I think i get away without AE on as I just learned to drive round the flat spots from the beginning not really knowing any better. It's pretty ok really except occasions about town sometimes- just some bogging. But can ride clutch a little and fine. I think I never notice the lack of extra punch when in the hills because I'll be higher up the revs and opening throttle more liberally if that makes sense. I imagine it would more noticeable in a heavier car with less torque. Will have a play with AE this weekend. Will also turn the over run fuel cut back on bit have more time set before it activates.

Rookie Posted October 24, 2014 Share Posted October 24, 2014 So if I change the spark retard mode to "Fixed" and say "-10" will that give me poser flames? Turns out this is exactly what you do hahahaha 3 Quote Link to comment Share on other sites More sharing options...

kpr Posted October 24, 2014 Share Posted October 24, 2014 I was talking at full load. 14's no drama at cruise. just below stoich spose to be hottest burn 1 Quote Link to comment Share on other sites More sharing options...
Testament Posted October 24, 2014 Share Posted October 24, 2014 how sure are you you have AE turned off alex? its on as default i think. you have to actually go and change the numbers to impossible ones to make it unresponsive/"turned off" Quote Link to comment Share on other sites More sharing options...
Testament Posted October 24, 2014 Share Posted October 24, 2014 Turns out this is exactly what you do hahahaha i can vouch it works 1 Quote Link to comment Share on other sites More sharing options...
downtrail Posted October 24, 2014 Share Posted October 24, 2014 Yeah ms1 you need to change it to all 0 or 99 or something like that ms2 you can select to turn it off or map dot or tps dot etc how sure are you you have AE turned off alex? its on as default i think. you have to actually go and change the numbers to impossible ones to make it unresponsive/"turned off" 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted January 11, 2015 Share Posted January 11, 2015 Thread bump! On new ECU there are Analogue inputs (0-5v) digital inputs, and temperature inputs. I understand analogue 0-5v and temperature ones, but what does digital input mean?Is that for something like a square wave signal from a crank angle sensor or something? I want to know what/how I could datalog some non engine parameters using those unused digital inputs, but before my imagination runs too wild I need to know what exactly it can or cannot do. I'm guessing any form of potentiometer is an Analogue signal. But anything like an ABS sensor isnt. Sound about right?If it's square wave or similar, counts as digital signal?

downtrail Posted January 11, 2015 Share Posted January 11, 2015 In basic forms yes you are correct. Quote Link to comment Share on other sites More sharing options...
Ned Posted January 11, 2015 Share Posted January 11, 2015 Depending on ECU etc, the digital ones cant all do cool shit. Some will be able to count pulses for measuring speedos etc, some can measure pulse widths, so how long something is high for, and others can only be simple switches for say a nitrous trigger etc. Same with using them as outputs. Most will have timers on them, but some will be super slow and won't work with great accuracy as they will be software timers instead of hardware ones. 1 Quote Link to comment Share on other sites More sharing options...
Roman Posted January 11, 2015 Share Posted January 11, 2015 Is this a factory sensor on any type of car that anyone knows? http://www.nzefi.com/product/bosch-fast-response-iat-sensor-turbo-na/ Quote Link to comment Share on other sites More sharing options...
