EA82T performance upgrades
oddcomp replied to 4moretoyz's topic in Old Gen.: 80's GL/DL/XT/Loyales...
lets see.... for boost i use a saab 9000 apc boost controller stock it gives you 10 psi if you tinker with it.. as much as the ihi turbo can do plus it has knock sensing that reduces boost if it hears knocking for fuel i use a megasquirt d.i.y programmable fuel injection controller very nice. no more maf complete tunability the base program code for it has recently undergone alot of .. alot of changes so it does a lot of stuff now... including ignition control try www.msefi.com and for ignition.. well i don't have a distributor.. btw this is a ea82t turbo in a 87 wagon ... i use a modifed version of the ford edis distributorless ignition system that is also controlled by the megasquirt -
i dislike the tight clearance between the fan shroud and teh fan puley nuts oof perhaps if i had tiny crack addict arms i would be fine

A/F gauge reads full rich, bad O2 sensor?
oddcomp replied to nkx's topic in Old Gen.: 80's GL/DL/XT/Loyales...
hmm i was under the impression<corrected since my last o2 reading impression i did in the msnedis thread thing as i have done a bit more reading now> that 1 volt was like full on way max rich .7 .8 ish are rich ect ect ect .0 being super lean or off throttle decelerating. or so my megasquirt shows things a analog or "needle" type voltmetter will show you all the dips and swings where as a digi type meter will sorta average it out unless its really expoensive -

first off it was a 87 well still is as far as keeping my foot out of it first run with full megasquirt injection and my current runing dis ignition.. i killed the auobox in it.. oops i will go under the semi false pretense it was the increase however small it may have been that finally killed the 3at... secondly my turbo with ms has no 02 bounce... if i stomp it it goes rich.. like i want.. actually 2 rich at fulll wide open as it bogs a tiny bit i need to remap that section of the fuel map at cruise the o2 stays at around 13. something to 14.7 air fuel ratio.. i will tinker when i get a new tranny in and try and get it to lean out at cruise for economy reasons also this is all done witha bosch heated o2 sensor i had laying around also the heated o2 had less "bounce" under suby ecu controll btw it is a narrow band unit since i have not found a good doner care for a wide band o2 and yes even with a "close" fuel map mileage imporved a tiny bit i expect better once i can actually spend the time to re map it as far as full o2 bounce on the suby ecu i got .00 volts up to .9 00 being super lean "at cruise/steady state condition" and .9 volts being just below the 1 volt<if i remember right> over rich side of things i have no idea if the autometer unit has sensitivity adjustments but i have schematics to build some really nice one's that do ... as well as electronic boost gauges hehe for my a/f meter monitoring i used my megasquirt box and had it hooked up to sensors like air intake temp and o2 sensor output ect i wish i had the suby ecu logs i made to show the diffrence -

ok having run both suby and do it yerself fuel injectinon with o2 monitoring on both the suby system at normal cruise will bounce around... and i mean bounce around alot! when you stomp it i certainly does go rich .... i lost my data log of the stock suby ecu .. i also found it unnerving... that the stock system bounces from wayyy rich to wayyyy lean at steady state conditions i also know that under boost the suby system while still sorta rich . is still not rich enough to help control detonation reason i can say this is the fact when i did my megasquirt and edis conversion in stages under suby fuel and distributorless ignition i had to retard the timing alot to prevent detonation at full boost 10 psi when changed over to megasquirt fuel inejction control with shadows' start up fuel map he made me i was able to run a more normal ignition advance map so long sotry short.. what you see at wide open is fine what you see at part throttle is ok for non modded suby's eh ecu just barely cuts it oops gotta go -
Links for mods, performance and otherwise
oddcomp replied to Numbchux's topic in Old Gen.: 80's GL/DL/XT/Loyales...
hmm i can tell ya how to do fogs witha relay or how to ditch your suby fuel injectiona nd ignition and go full custom.. dam ineed to make a web site that no one can really understand lol -
XT Spyder Intake Throttle Body Question
oddcomp replied to RallyKeith's topic in Old Gen.: 80's GL/DL/XT/Loyales...
well as long as it matches up electrically your fine you might have to rig up a small "cherry" style switch to act as the idle or wot switch as wella s teh tps wiring as far as the turbo xt and the n/a xt i have no idead of there is a difrence sorry i forgot the stock suby's use those mine just usses tps and map sensor.. but its not a suby ecu either so its easier for me to adapt things -
XT Spyder Intake Throttle Body Question
oddcomp replied to RallyKeith's topic in Old Gen.: 80's GL/DL/XT/Loyales...
go look in the junkyards at 80 dodge mpfi and turbo's they use a hooley throttle body a small adapter plate might be needed or if you wanted really nifty go look at the ford probe turbo's and mazda turbo's and a few n/a mazda's i think a few otehr cars have ti also but anyways those have a cool 2 barrel staged throttle body but it does need a adapter plate to make it work at wide open i think with both plates open its about 1.5 times bigger than the suby throttle body -
oh well next time

yes that would be skips setup

Anybody Ever Bandsaw Apart An EA82T Head?
oddcomp replied to NorthWet's topic in Old Gen.: 80's GL/DL/XT/Loyales...
actually now that i think about it the "better" way to do it instead of merely cutting one if half would be to make 10-20 "slices" out of it so all the port work could be inspected on slive by slice basis -
Anybody Ever Bandsaw Apart An EA82T Head?
oddcomp replied to NorthWet's topic in Old Gen.: 80's GL/DL/XT/Loyales...
i do not have any spare ea82t heads... but i do have a metal bandsaw... -
yeah that garnizzle is one hell of a guy!
-
i.. traded for it.. 2 stock recirc style units off 2 diff cars i di dnot know i was getting the hks one at the time i was told it was a blitz
-
my hks ssqq bov has a nice adjustable bolt in it to accomplish the same thing
-
yeah see.. i kinda figured that.. and almost made mention that this is not one of those party's... but i figured hell if anyone is a tranny and can turn a wrench then why exclude them lol
-
yeah i totally agree
