I'm sorry but the guys from dsmlink are shooting themselves in the foot. V3 actually looks good, but v1 and v2 are pretty elementary. I am actually about 60% done with my own setup that I have written and connected myself. I am not basing it off of dsmlink, but it will have all the features that any tuner would want. I started only a year ago, when I took my first java class!
p.s. - My setup will use usb, require low computer requirements, and it will be free.
That is really awesome!! Have you tried an Evo8 O2 sensor for the front?

An O2 sensor is an O2 sensor. 0-1v signal and heater circuit. His O2 code is probably due to MAF scaling and Injector scaling. His car needs a tune. I just scaled his injectors down to 450cc. The car is still using a 2G maf, by no means is it anywhere near tuned, just runs. I was ready to get out of the shop and go party. Told the OP he will need to set up something with Scott to get tooned.
i have done the evo 8 ecu swap in a 4g64 and the o2 sensors are the same as i have used a 1g turbo o2 on up to a 64 nonturbo o2 sensor and am currently using an innovate o2 simulator off my wideband.. The o2 sensor may however be bad and need to be changed.. also if ## scaling is crazy off u may get a delay entering closed loop which will also raise ## idle and cause idle codes.... Try messing with that scaling -- set it higher than 450 and see if that helps ...
...am currently using an innovate o2 simulator off my wideband.
no dont raise the maf scalings --- i was referring to injector scaling only... for maf size i have 257.7 i attached my maf scalings for u to view... maybe u want to try something close to that and see.... its the mafscalings.jpg file... try my numbers ----- also what is ## wideband reading at just idle??? it ## running way rich or too lean then ## trims are nasty..... GET a program called scan tech it will tell u when ## car is in closed or open loop also -- im using 450 cc blue tops from a 1g and i use 424 injector scaling -- u may need to raise or lower depending on ## trims
just remember what section ## working on because one little mistake in numbers causes fuel or timing problems.. Remember to adjust the maf size to 257.7 and for the scaling follow what i posted... Also u will have to play with injector scaling and injector latency to get good idle of course.. But if ## scalings are incorrect for the maf all that goes haywire altogether soo... Post up ## fuel trims from evo scan if u can --
any improvements
if u are sure the wire is connected properly and is correct wire then i would say the o2 sensor is bad... are u sure u have the heater wires and signal wires hooked up 100% right??? maybe to verify u want to switch the rear o2 pin with the front o2 pin to verify that the ecu is reading the front at all... this is to test the port on the ecu to make sure its working then u know u have a bad o2..
It will be interesting to see what happens with this.
The race is on to see if people decode the layout of the late model 2G ECUs or go the EVO VIII ECU swap route. As you'll note some progress has been made on getting EVOflash to support the MH7202 based MD35940X ECUs.
