ok ill go take a ride in a little bit and data log that one. its wired in with factory harness, the pip doesnt do anything except cut spark if i removeI need datalogs with no autotune in order to trim fuel.
26* cranking is alot however the gray TFI is 'push to start' meaning that if wired correctly (like factory) the tfi gets a 12v cranking trigger that retards the timing to the mechanical offset. Stock is 10*
15.1 cruise is what i have set in ur afr targets. So autotunes gonna match the afr targets set up in the chart.. You could fatten it up if unwanted to but id just autotune the ve table to near perfection then just change the afr targets to what u want.. Easier then redoing the ve to get the target to match... Datas lookin good tho. Not seeing any major problems.. Keep it up. Soon we will get some boost cells rollin.. And whats up with ur timing? That should of been set when we did it. Unless u moved it..i did an auto tune last night was a quick little ride... i have to figure out my alt issue,,, always chasing something.... seems phat at idle n looks like 15.1 on cruise ...but im sure auto tune sees that lol
i just posted the tune.. sorry forgot that. was not on auto tune . i am going to tear it down tmrw the new turbo cam is here now and im not sure if im chasing valve springs or what.... something is weird when i try to go above 3400 rpmOk do you have a tune file to go along with it? and were you running autotune at the time?
i bought the cam and was going to put it in another engine that i was starting to collect parts for. the cam that is in it is a small rv hydrolic flat tap, the new one is a solid roller .... custom ground for boost . the 3400 rpm issue is something i noticed when i lean into it.ok, well then i wont bother adjusting the tune file at all... your cam swap is going to completely change the tune requirements. Why did you decide to change the cam? and why is this the first i have been informed of an issue at or above 3400?
ok it seemed like the idle was to low when i woild back out of it ...it would want to sorta stall. if you think im not going to gain much ill wait on cam change i just have a chance tmrw to tear it down,, i wanted to try to figure out if it was to much ve under boost. im sorry if i seem all over ive been chasing allot of dumb problemsThe issue at 3400 is likely something in the tune, although i have seen another car with a similar issue.. This may dictate some increased tach rejection in the software. Let me know when you are done with the swap, your car with an RV cam should be idling in the 700 range... not the 1k range i see in the datalog.
