Woot major update the beast is on the road and she pulls pretty good for 5psi on the t3t4 60 trim! I do have a cas gremlin I need to work out but other than that she seems ok I've driven her twice to work and back which is a major feat since I work across town at least 17 miles away! Hopefully the CAS I'm getting will fix the problem if not then I have to figure out something else out.

Nice, another CA on the road! Don't go too crazy until you get that beast tuned!

Heck yea! Congrats!

Izento dont worry I got do the break in and work out the bugs once that happens Im going to dyno it in the state its in before adding bigger injectors and tuning it if stuff goes the way I want I got a nistune ecu coming my way.

I need to figure out my no start/ running on 3cyls when it does start issue. Ive checked spark maf is good I think its an injector issue tho.

I know you said you have spark, but the Ignition Module is my first guess. It's much easier to initiate a spark outside of the combustion chamber than inside. Because of that, I started using one of these to test for spark;

How does that work never used one

It connects between the plug and the coil and lights up when the coil fires.

Well my new issue is something keeps killing my cas's I grabbed a working one from the junkyard and.after 20mins of running its dead I dont understand why also along with this issue it keeps.throwing my timing off also.I get fuel pressure intermittently. But that might be a separate issue.

If you have a bad CAS, don't worry about fuel pressure until you have that sorted out. The fuel pump relay is based off of input from the CAS, ie; the ECU only closes the relay if it's getting a constant signal from the CAS.

Awesome thanks that's good to know. I thought I knew a lot about these motors lol between you and Dee I've been schooled this week a lot. Dee helped me a lot and because of him I have figured out my problem apparently I am missing the alignment pin for the timing cover which throws off the alignment of the cas which in turn causes it to take a s***. I have been through 3 cas's and Dee has just sent me another one but it's not going on until I get the alignment pin.

Yea, you HAVE to have those alignment pins for the upper timing cover. You're not the first (nor will you probably be the last) to kill multiple CAS's from that.

Yeah I just wished I'd asked sooner what the problem was so I wouldn't have wasted money. But Shi goes the life of a car guy...

Car is running and has been for the last 3 days woot!!!!! so happy to have my baby back on the road and boosting again! thanks to float and boost_boy for the help! now I have to wait till after xmas so I can buy an safc that works and get her tuned I will be buying (hopefully) a nistune ecu that my buddy has and wants to get rid of. Still have some stuff to do in terms of cleaning up the bay a little and doing something about my shifter hole thats been massacred by the previous owner. heres a few pics I took today.



some stickers I added

Lookin' good!

Thanks! she needs some love but the most important part is over with and that is she runs!

Ok so I realized last night on the way home that if I go above 3/4 throttle I hit fuel cut at 5500 but only if I get on it like from 1/4 throttle to 3/4 throttle. but if I ease into it I can go all the way to seven no problem is there a reason for this? Is it because the voltage to the maf doesn't spike when I ease into it as opposed to just romping it?

Quite possible. If you're getting a boost spike when you hammer it, that could hit the fuel cut.

My boost gauge reads 5psi solid in any condition if I tag it or if I ease into it.

Hmm, well unless you have a way to log the MAFS signal, or at least a way to monitor it, it's hard to tell what the ECU is doing.

True I need to hurry up and get an safc2 to replace mine. In other news I smashed a n/a z32 it was sunday around 4 am and I was on my way home from work when this z32 decided to ride my rear bumper (freeway was empty) so I downshifted from 5th to 4th hit about 4k by 55k I had put about three buses on him before I shifted to 5th I was only at about 35% throttle.

CA18DET's; doing more with less since 1986

SO true lol I installed my wideband today so I can get a good look at my afrs.

Ok so at idle my afr's a re 11.1 cruising is at 14.7 to 15.0 and if I get on it it drops to 10 -11 stock fueling and on 5psi from the t3t4 I'm running. What do you guys think?

Stock FPR + Walbro? It sounds like it's over fueling at idle. It should be in closed loop at idle (sweeps between rich to lean)

no I have a adj fpr and walbro 255lph. That's what I thought as well but it stays at 11 sometimes 12 sometimes 10 but doesn't sweep.

Do you have a heated O2 sensor, or a single wire? Sometimes a single wire, especially with big exhaust and no cat, won't get hot enough to work properly at idle, and so you won't get the sweeping you should.

I dont understand what you mean. The o2 for the wideband is the one it came with from aem if you mean the stock o2 its a double wire but I am running open dump for now...

Wait, you're running a wideband AND the stock O2 sensor? The wideband has a simulated narrowband output so you can eliminate the stock O2 sensor and run that output into the ECU. It's more accurate and will keep you in closed loop at idle as well.

I never knew you could do that I've always run it this way with both. How would I run my wideband to the ecu?
