here are the addresses in evoscan for my 2 byte load adress 00 and 01 and function is 0.3125*x

in ecuflash it is 00 and 01 those values are set to 35164 and 35165. in the mut table mut00 is 895C and mut01 is 895D. i got those from the official 2byte thread

 

I think i know why the loads and idc's are so high. The car has a junk safc2 on it. I wanted to leave it on there just solely for the rpm and knock gauge it has. For one those are off by the way lol since it says i get 15 counts of knock sometimes. But if the fuel trims in the safc were increased wouldnt it affect the load and idc of the compuuter? Im thinking the safc works by intercepting the signal from the maf, and the adding extra fuel by changing the signal to trick the ecu into thinking its bringing in more air. More air equals more load and it adding more fuel with more load would equal more idc right? Im also thinking that when it messes with the maf signal and the ecu reads this and sends it to evoscan it is the normal load plus what the safc is adding in. When i get time im going to zero out everything in the safc since i forgot to last time and do another half run log.. im definately not taking it to 6k again and risk blowing my motor if thats not the issue.

 

IMO I would ditch the SAFC

 

i am now that i have something better to tune with lol. do you think maybe thats whats making it have such a high load like you said since it basically is altering the maf signal going to the ecu?

 

I'm not familiar with how the SAFC works so I couldn't tell you, sorry!

 

Thats exactly what it was and why the car was hitting such high loads and why the idc was over 100% and the reason the car was cutting out. im guessing since the main thing the apexi safc controls is the maf what was happening was the ecu was getting the reading from the maf+ the extra fueling from the apexi safc. that would explain why the first tune was so lean. im guessing they had installed the apexi safc and tuned it really lean and adjusted it externally with the safc and then when i reflashed the stock fuel maps in without zeroing out the safc it was factory rich+ the extra fueling coming from the safc so the injectors were maxed and the load was reading really high.

i zeroed the setting out on the safc and did some logs. at idle everything was the same except the load. load went from 40 to 30 with it zeroed out. i then felt safe enough to do a wot pull from 2500 to 5k to make sure my assumptions were correct and to keep it from breaking up again. max load i hit was only aroung 270 this time. injector duty cycle also dropped quite a bit from the 106% to only mid 70%.

so im pretty sure im ready to start really getting into putting my own touch on the car. first question and probably a dumb one but what do you start to tune with first? i plan on doing the tune in increments say 2500-3500rpm, 3500-4500 etc etc. should i start with fuel or timing or do i tune both at the same time? i get the whole thing of setting it to around 12.5 during spool, 11.5 at peak and tapering into the 10's at redline... do i do that with the map and then go do a log, then advance the timing until i get knock and then back off the timing? or should i adjust both at the same time? sorry for the long post and newbish question im just not wanting to f something up or give my crank a suntan.

 

I found this to be a great help when i was starting out http://sevo.motionforum.net/t15-guid...-with-ecuflash

 

decent writeup except its not finished. i owuld have like to have known more on the timing part.

if i have no dyno or any of those calculaters the guy talked about how should i go about adjusting timing? from what he says advancing timing until you encounter knock isnt always best. or is that how i should do it since my butt dyno isnt very accurate? and is it the same as say the fuel map where i only tune above 100 load to keep the stock like driveability?
