all right guys today we're tuning this 1g dsm it's a tsi it's 1992.
uh it's got a built engine it's a long rod turbo tuff combination
um yeah i'll tell you a bit about it in a second things pretty gnarly it is a hall tech ecu car
pump gas and then some ignite red so some a little bit of flex fuel action going on check it out
all right so here's this one g is a 6266 precision it's a gen 2 6266 haltech efi sir 1500 elite
1500's got their coils set up on it just you know the smart coil ign 1a style stuff um yeah so
things pretty cool 5 speed car we're running 93 octane first gonna get some drivability stuff
nailed down with it and then set up some flex fuel and uh put this thing up on on ignite red and see
what kind of power we can make with it hoping for 700 wheel nothing too crazy cars obviously caged
work in progress you know i think always like all of them are but he's driven this car i think
400 miles he said before i got here today so i'm gonna jump into this thing and get the pump gas
stuff dial up and uh then we'll we'll see what we can make on some better fuel there's a fuel
injector clinic 2150 injector so we've got a bit of headroom there got to make some jam with it so
all right i'm pumped gas on gate pressure which is 27 pounds we made 478 381 i didn't lean on
the thing too hard i'm gonna go ahead and pull the pump gas out of it drain the system
and throw some ignite red in it and turn the boost up a bit like i said that was only a 27
pounds so not a bad number i didn't really the timing's really conservative it's just meant
to be a drive it around the town kind of tuned up there so didn't really try to make any power
with it but uh yeah on the better fuel we're gonna turn this thing up and be hard on it so
so
all right that was the best hit we made unfortunately we can't keep a coupler on it check
this giraffe out so what was happening here is uh yeah see it looks pretty crazy but yeah i made six
652 583 before i get too carried away um so the graph the graph is all weird like that because
of how i set up the open loop boost control table basically i put a ledge on the right hand side of
it so that uh it's x duty cycle until a boost number and if we go above that boost number it
tapers duty cycle out of it what can happen is if you have the taper too drastic it oscillates
like that that's exactly what happened so when i did that i lifted it blew a coupler off so i
corrected the boost control thing put the coupler back on and then unfortunately the next hit it
blew the coupler off immediately um the boost control was stable but we didn't make it real
far like 6200 rpm so it made like just shy of 600 wheel um but uh yeah so this is the coupler
that died this throttle body gear so this is a drive-by wire car forgot to mention that earlier
and there's just not enough of a lip on the throttle body um that said though i'm comfortable
with the tune-up so we're gonna send this thing on down the road he's gonna fix that throttle body
flange and then we'll uh we'll work on some of the boost control stuff um once that's sorted out and
dial it in a little bit but as far as the fuel and the ignition time he goes i'm happy we just won't
be able to give him a solid finished dyno number for now but maybe we'll talk him into coming back
and uh making a hit later in the future but nonetheless 650 wheel is uh not a bad number
um but it'll surely make his goal of 700 plus these things are if you know much about the
4g 4g63 engine combination and then the gen 2 precision 6266 i think we just did an evo not
too long ago that we made a little over 800 wheel on the same charger so definitely plenty capable
setup um yeah that's it for this one i'm gonna get this thing unstrapped and hopefully we'll
we'll see this thing again in the future and try to make a a number with it again and have a little
bit more successful time but all in all not a bad day things happen we move on thanks for watching
