ummm i think my car should be in a mental ward

[thehookeup]

ok... so my car runs great, but i have to tell you the whole story leading up to now........

a week er so i was going to the legacy meet in p tizzle here. and my FCD shorted and fried my turbo ecu. which was a real pain in the ass. so doug, craig, and i sat in the middle of the street trying to get my car running. but at the time we didnt know that the computer was fried..

so doug and craig went on without me i stayed behind in clakamas trying to get it to run. but no luck. so my dad came out with his flat bed trailer to haul it back to beaverton. and guess what, the bolt that holds the trailer on the trailer hitch, broke as we were pushing the car up on the trailer. so the trailer popped up and ran right into the back of my dads perfect truck. doing about $4000 worth of damage......thank god my dad didnt flip out, he took it in stride and just delt with it.


so we get the car back , and after conversing with all of you and doug, i put a 91' N/A ecu in my car. i also got the MASS air flow sensor out of the donar car. switched the cam and crank sensors and then fired it up. but before i did i drilled out my old MAF so i could put the N/A sensor in. i couldnt use the N/A sensor housing because i have a blow through MAF that has beads welded on it so it would blow off.

It ran but it had a CEL. number 49, which is "Use of improper air flow sensor". i switched back and forth between both sensors and redid the soldiering that i did, just to make sure it was good.

so finally i decided to put the stock turbo MAF back in. i did, and the car would idle fine but run like shit. so earlier i was diconnecting the blue wire leading in to the MAF because thats what your supposed to do with the N/A's. the connection was back in and and not secure i guess. cause i accidentally pulled it out while it was running. The idle went to better than the stock ecu, and the CEL went off. just by diconnecting the blue wire. haha

totally by accident did i make my car run great.

the car pulls pretty well, its a turbo running on a NA ecu. it has a little more lag, but that is just due to the fact that the turbo fuel map and the NA fuel maps are different.

so no CEL, STOCK MAF with the blue wire disconnected, and running 17 psi it runs pretty damn good. bring on the piggy back....
oh yea and the cool thing is i dont need a FCD haha. i will have a technical write up coming tomorrow er so. For those who dont wanna screw their comp with a fcd. wont really improve performance but it will make it safe for those who are not confident enough to make the FCD in the turbo forum (BUT THE ELECTRONIC FCD IN THE TURBO FORUM IS A GOOD ONE, IT WORKS GREAT FOR A LOT OF PEOPLE) this is just a crazy f'd up alternative....

Got any way of checking your A/F ratio? The N/A injectors are different than the Turbo injectors, theres a good chance you're running super rich

The timing is probably quite a bit more aggressive too, but I dont think it's something you would have to worry about running stock boost levels.

[thehookeup]

oh i know im running rich. i am running 440cc injectors. but the car seems to be running great. in fact my idle is a thousand times smoother and i only start to have small intermediate misfires at like 5,000 rpm. but other than that, it runs great i am getting my perfect power hopefully this week. so ignition and fuel wont be a problem anymore

[dzx]

I wish my car freaking idled. I think I fried the rear main seal by over heating the engine a couple times. Now the thing drips oil.

I haven't been on in a while but from what I remember, a lot of people were having problems with the perfect power.

[Manarius]

oh i know im running rich.

I bet you're getting like 10 MPG with that setup.

[thehookeup]

i have heard different things about the perfect power. but everyone that i know loves it.


well when i first did my G head swap, with the stock ecu and the 440's i was getting 8 MPG yea it sucked, but then after about a month i was getting 17-22mpg which i was just fine with....

now that i have the N/A ecu driving around yesterday i was getting somewhere in the range of 15-17 mpg. its definatley rich on start up thats for sure
