knight Posted March 10, 2011 Author Share Posted March 10, 2011 really? what's the map ur now running? and how you compensate vt unmatch?All i've done mate is changed low to hi point to 5000rpm thats it but remember i'm running,,,,,,S/S Fat Chome Intake Pipe -- Cone Filter4 to 1 S/S Manifold -- Super Sprint De-Cat -- S/S System -- S/S Back Box Round 3" Round So that maybe making a difference!

mc2_vti Posted March 10, 2011 Share Posted March 10, 2011 oh no wonder ha. mine is stock so maybe its the difference good for you tho! Link to comment Share on other sites More sharing options...
vtivtec170 Posted March 11, 2011 Share Posted March 11, 2011 can you explain the low-hi hi-low thing please.does it mean vtec comes on at the low-hi and drops off at hi-low?so if say low-hi it 6k rpm and hi-low is 5k..............................you get to 7k, use engine braking to 5.2k, throttle it again and its still in vtec?

johngreen537 Posted March 11, 2011 Share Posted March 11, 2011 Low - Hi = VTEC engagement, from low to high revsHigh - Low = VTEC disengagement from high to lowSo basically, high to low gives you longer in vtec on lift off! But set it too low and you'll be in vtec when you don't need to be, or the the low high too high and you'll come out of vtec on gear changes etc!

mc2_vti Posted March 11, 2011 Share Posted March 11, 2011 x2. And normally the lo>hi will be around 100-500rpm higher than hi>loand apexi neo has a funtion called vtec unmatched.For example, when u set vtec point lo>hi = 6000rpm, and hi>lo =5800rpm.so you will run on high cam when rev>6000rpm, but your car ECU during 4400-6000rpm is actually running on high cam map (cause ECU doesnt know you're on low cam), and Neo has a compensation setting for you with this unmatched situation (running high cam but on low cam map, and vice versa).there are also parameters you can set for vtec engagement AND / OR with pressure, throttle position.surely you should tune all these by a dyno run and get a wb o2 sensor to tune with optimum settings.just one thing you can't go crazy with the settings otherwise the ECU may run beyond the base map and throw off code.

simpo Posted March 12, 2011 Share Posted March 12, 2011 i am glad i dont have one of these because i have no idea wat you are talking about Link to comment Share on other sites More sharing options...
mc2_vti Posted March 12, 2011 Share Posted March 12, 2011 lol... think of this way, buy a cheap used one just for bling bling and bring a nice colourful monitor to show some car info.tomorrow simpo u can have a play with ours and you will get an idea what this little thing is.and today sat on paul's car you could really feel his vtec kicking real strong!but at some point when fund allows I will get a standalone to tune it properly.tomorrow cant wait!!!!!!!
