Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

I cant seem to get my lsvtec turbo running.
i got it started but it only seems to be running on 2 cyclinders and is ultra rich.
i tried running a stock b16 basemap on the ostrich converted for the 450cc's.
when it ran it was pig rich and seemed to only be running on 2 cyclinders. All the cyclinders are getting plenty spark and when i look in the cyclinders two and four are dirty and 1 and 3 are clean. The engine is on a fresh build so 2 pistons are still shiny. Also when i remove the plugs they are wet and fouled. it ran only to about 1500 rpm with my foot on the gas... i cant understand why so much fuel is dumping into the engine with stock maps... i treied switching to non chipped stock ecus and its the same thing... just rich rich rich even with 240cc injectors. i even swithced injectors and dizzies. whats goin on here? btw i do have an AEM fuel rail on the car but stock fpr.

why is the car so damn rich with stock maps??

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Stop here...do not pass GO until you figure out why it is only running on two cylinders.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

ok, I passed go ( two cyclinders running because two damn rich and wet ass plugs). I used a base map off your site (joshlsvtec) and had to cut 40% fuel to make it run and idel well. so now i have to tune more... cuz even tho it runs decent now there is still hela tuning needed... i waiting for my friend to bring his data loggin stuff.
can i have $200 now tho?

any imput on ---- shiz is apprecated i are noeub. :8

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Wow...40% is alot...you sure you scaled it back for 450's in the first place?

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

;D He scaled for 45cc.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

yeah i have 450s on the fuel multiplier...
a 45 is what i keep in the glove box :8 oley!

no but seriously.... my car runs insanly rich with even 240s on a stock map... so i dont get it...
it wouldnt even start with the basemap... so with 40% off it ran ok and but still rich according to the wideband.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Hmm...you tried checking the stupid ----...like maybe map and tps plugs backwards? I've seen this do exactly what you're describing quite a few times.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

stock fuel pressure or what? check for codes..

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

do u mean that i have the connectors for the tps and map switched around or do u mean that the plugs themselves are on backward?

Ill have another peek at the car this weekend. No codes at this moment.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Do you have a solid cheack engine light. Your eco might not be soldered correctly and it's not reading the chipor ostrich.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

No, connectors themselves switched around. It won't toss any codes either seeing both map and tps run on 0-5v range.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

the car ran rich as ---- even when i switched the obd0 stuff back on.
i'll double check the solid cel thing on sunday... i live 3 hrs from where i keep my car / tools.
i'll holla.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

It will even as obd0 if the map and tps are switched. Same thing happened on my friend's obd1 swapped hatch with an LS...map and tps were swapped and it tossed thick black smoke out the back. Once rpm's started to climb it cleaned up a little but not alot. Switched the plugs around and it was fixed.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

The connectors werent switched... i wish they were... ???

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Ok, how bout a little more info on the setup and chassis then? And what ecu and program you're using too. No resistor box with the dsm 450's perhaps? ASSuming you're using Crome, did you try using a p72 map instead? I've heard of people sometimes having issues with p30 code and such, maybe worth a shot. Oh, and on a side note, even when scaling back for 450's you're going to have to increase the idle area of the fuel map to take into account for injector latency.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Alright.. here goes.

89 EF hatch

rywire obd 1 conversion

lsvtec
b16head b18 blovk
gsr cams
ls tranny
t3/t04e .57 trim
450 dsms
2.5 charge piping
large ass front mount.
aem fuel rail
stock regulator
hi flo fuel pump
3In DP
chipped p28 on chrome + ostrich

Even when i converted the car back to stock 240 injectors and stock obd0 ecu the car still ran retardedly rich... it doesnt really make sence...

oh and btw mr.slocrx, i do appreciate your help :y

if u need any more info holla!

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

No problem...I'm here to help if I can :)

Check your fuel rail pressure...when I installed my walbro 255lph hp pump, it shot my rail pressure up to 65psi+. It ran rich as hell until I turned the fpr down all the way, but my return line is still too small and I still can't go below 42psi at idle :P More than likey that's why you had to scale back an extra 40%.

On a side note, did you run the ls/vtec n/a? Reason I ask is I'm thinking about slapping a quick b18a1 stock setup together with my b16 head and I'm wondering how the lower pr4 piston compression does in n/a form...or if I should just put my pr3's on there like I originally intended. :l

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

im a lil stoned, so well see if i can make any sence.

Ive never ran an ls vtec before. One of my boys had an EG with a b16head and b18 block with pr3 pistons (b16a1). It ran pretty awesome.... low 14s i believe with an ITR tranny...

EF:

I used to run the same fuel pump with a stock b16 turbo... it car ran fine on stock ecu. Although i used fmu and afc hack.... it blew... but i was on crack boosting 14psi... fun tho :y

so then i decided to convert to obd 1 and go lsvtec w/ arias 9:1 pistons... Now it runs like ---- off the get go. I wonder if it has anything to do with my fuel pump... I replaced my main relay by soldering a little while ago tho... i wonder if their are any cheap ways of checking fuel pressure without buying a guage.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

Not really any way to check fuel pressure without a guage. I put the b&m fuel pressure gauge on mine, that way when I have to adjust I don't have to hook up a guage and then unhook it when I'm done.

Re: Lsvtec turbo problems/ostrich/crome/ too rich even on stock maps :s
 

alright... im gonna source one... any other thoughts?
