been quite a while, so i thought i'd do a quick update here, of where i left off for 2021... the turbo smart compgate 40 is almost a drop in part.... the outlet v-band flange is opposite from the tial. so instead of a male/female connection, it ended up being a female/female connection. not ideal, b...

ok thanks!

yeah i really didn't like the thought of giving up response.

if the comp gate 40 truly is a drop in replacement, that's easy enough to try. i'll get that and the fuel pump on the way.

so i did some more testing, running direct boost signal to the bottom wg port (4psi spring), top port open to atmosphere. boost holds pretty decent till 5000rpm, then creeps up in step with rpm until 2 things happen- afr starts to go lean at ~12psi, and in some cases, boost can continue up till it h...

thanks for the vote of confidence! haha this is actually very similar to what i do for work- troubleshooting and commissioning equipment. the big learning curve has just been learning the acronyms and getting familiar with the software. definitely feels like i'm getting to know the process now. yeah...

yeah, i tried the 10psi springs twice. i think it's actually worse now with the new maf housing. i'm probably exaggerating a bit. it just hits my 15psi limiter, and i let off. in reality, if i could stay into it long enough, it would probably spike then settle down. i have bench tested the wg a few ...

Thanks once again. When I tried the 10psi spring combo, it was just straight to the moon with boost. I guess I could try something in between 4 and 10, but if that raises the top end at all, I’m afraid I’ll be up against another problem... After reviewing my last 2 logs, I’ve been adding a bit of fu...

thanks pl. i was already wondering if that would be a good test, so hearing it from you got me motivated to try. with no spring at all, top port open to atmosphere, bottom port run directly to the boost reference. i was climbing a gradual hill, which i figured would be a pretty good way of testing t...

i don't get it... still overboosting. the boost controller is venting as much as it's capable of, from the top of the wg. if i drop down to 3rd and pin it, it goes over 15psi+. 4th gear seems to hold, but i don't have a safe enough stretch of road to hold 4th right to 7000rpm. why would 3rd overboos...

today's attempt was just another adventure in overboosting. however, i did make it to 5200rpm instead of 4600 this time. and i think the mid range boost is a bit better that solely relying on the 4psi spring. i'm having trouble wrapping my head around how this 2 port manual control is supposed to be...

great news about the boost control!! unfortunately mine is fp1 though, so i'll have to get it reflashed. depending on how things go with the current control setup, i might just wait till winter and send it away to whomever has the rom burner up here in canada. put the 4psi spring back in, and figure...

could this be repurposed to control a boost solenoid?

i seem to remember that my engine came with an oem boost solenoid, but i don't see any way of controlling it in nistune... unless i'm missing something.

ok, back again to update this post after some emails between matt and i. 800us has proven to be the correct starting point for latency. this has been verified in another post in the general section, titled r35 gtr injector latency. (currently adjusted to 870 to correct idle afr) turns out the 444hp ...

awesome. yeah, i've already been getting much better results in the 800-850 range after matt's recommendation, but it's great to have you validate this. funny how sard lists it as a 550cc also. kinda adds to the confusion over the flow ratings. but using 570cc in the injector resize and 800us for la...

Yeah odd. Mine is definitely not working the same way. My little pop up window is also smaller, and doesn’t have the hints to go along with it. Doubt that makes a difference though. Just weird. But manual entry is working. ***update: the +/- keys do work at raising/lowering filtered values. works on...

today's update: since it seemed like my load scale and tim was close, i decided to take my first stab at making some fuel map changes. doing % change while looking at filtered values raised the fuel in the cells i selected. very confusing. doing % change while looking at raw values lowered the map. ...
