CA18DET and engine management systems!

[ca18donny]

I have stock internals. 880 injectors gt2871 turbo running 18 pounds of boost full 3 inch exhaust and the AEM with innovate wideband.Also running 93 octane gas.

yea get those AFR's sorted before it starts washing your cyilnder walls down and making oil soup out of your motor oil.

i've had a megasquirt but didn't like the fact that u have to configure it to the car u are using. so i sold it and went sds em4F. i'm now ready to tune it and was wondering if anyone using sds can post their fuel/ignition maps so i can have a good start point. i like the sds because of it's simplicity. i'm running a t3/t4 turbo with 560cc injectors.thanks

I can't post fuel because I'm running E85, so my fuel values are much higher (same size injectors). As for timing for the CA, I'd say set your idle timing to 15°BTDC (500,750, 1000) Then ramp it up by 2's until you get to 27°BTDC.

On the MAP timing values, add 1° of retard per psi of boost.

Just like float says, I too use SDS, but throwing fuel maps across the internet isn't the wisest thing to do because someone will always find fault with what you do or worst, your engine gets damaged. Your most important settings will be your man. /press which will be the base-line for your rpm/fuel and if you like, I can help with that info off forum.

well thanks guys. my email is [email protected] so jus give me a shout. would really like to discuss ur ideas and experiences. one more thing, anyone has experience installing tomei lash type 8.8mm lift, 260 intake, 270 exhaust procams?

[themadscientist]

Megasquirt utilizes a Motorola 2.5 Bar Map sensor which is mounted on the board itself and has a tiny hole in the case to run a vacuum line. Someone people dont like this, they have yet to explain why they said they dont like that when people with boost gauges run lines the same way.

I don't like the idea of hot, oily, pressurized air bring routed to my engine's brain. I have never seen a pressure sensor fail and leak but s*** happens and if it does I would prefer it do so in my engine bay not inside the case of my ECU. I would definitely use the external option.

[ser20det]

Tms.

You have to know that the new haltech ps2000 come with a inboard map up to 22psi of boost. But you have the option to run external map sensor if you wand to do so.

i think i will be going that route

[themadscientist]

I hear some guys like to have other guys PIITB too. That others do it doesn't mean it's a good idea. That being said, as I freely admit, I doubt the chances of it happening are worth the worry but I do.

[sjbsuperman1425]

ROMulator ftw!!! http://secure.transtronics.com...d/328cheap, effective, keep all your stock sensors and coil packs unlike megasquirt, etc

im looking into NIStune right now. Now with that installed, i dont have to keep burning new chips like the ROMulator correct, and this will just need a laptop, wideband, and the software for me to start tuning? it also keeps all the stock sensors and the ability to self-diagnose correct?

i'm having some trouble with the sds em4, jus looking for some help. maybe boost_boy or float_6969 can help me out. really desperate right now. need the car started.

[float_6969]

Hit me up on AIM. nismoman240sx

[niswiz]

thing is i get fuel and spark! engines jus keeps swinging them sometimes give me a big backfire that shakes the whole garage. i'm desperate cause i need the car running.

[float_6969]

Start a new thread an I'll address your questions there.

Sounds like a magnet or two is in backwards (ouch) .

CA EMS impressions.

I don't like the Megasquirt b/c you either install a crank trigger wheel with hall effect sensor, or wire up just the home output to the megasquirt. Both of these are really low resolution timing solutions, and I think that with a CAS capable of such high resolutions its not worth it.

AEM I don't like because of the software experience (but everyones is different) and the CAS issue that is shared with the RB community.

I have used the emanage and LOST AN ENGINE because of it, it too produced timing errors from not being able to properly read the cas timing, and stopped the firing of injectors to only certain cylinders. This was very frustrating to re-check the engine harness 5 times, and still have the unit producing errors, which ended up being internal and costing me a rebuild. (I think dee sold me a couple pistons for it.. thank dee).

The haltech has been one of the only solid tuning platforms I have used paired to a CA, where it is reliably reading the CAS and I am comfortable with the tuning SOFT.

I would also go for the PFC if I was on a budget, but they seem to be so rare that they are very expensive on the resell market, making it just as expensive as a Haltech plugin system.

i hope its ok to ask this but im looking for 250-300whp on my CA18 setup, and all i have is an Apexi S-AFC II. Would that suffice to meet my requirements or would i have to purchase one of the systems listed here, and which one? cause i dont know alot about tuning!

[zombieslider]

so i take it no one on heres used the nistune because i didnt see any replies to questions. A local shops running a deal $600 total for the nistune and to tune it sounds pretty dam good to me.

I think you could get away with it but you would be so far off that unit's intended application, one wrong move and you are done. How are you going to tune your timing? You could likely get away with a remapped ECU and a Z32 AFM. There were plenty of CAs back in the day with that setup. With the plethora of user-friendly SAEMs out there, though, why would you do that?

Well that sort of helped but at the same time it didnt. From wayht i can gather i can have the ECU reflashed and tuned that way. I dont plan on Tuning this car myself as i dont have the materials nor the knowledge...but i was told I had to provide a standalone or a tuning system in order to reach my goals.

I always thought that you could go to a Shop and they would have a method of tuning where they could tap into the ecu and tune from there? like i said before im still trying to aquire as much knowledge as possible...if anyone has free time to chat on aim rather than posting my screen name is RjTheThug lol

A couple 300+hp CA18s on sxoc run emanage blue.A SAFC is an extremely potent tool IN capable hands... producing hella fast street cars.Fine example here; http://forums.club4ag.com/zerothread?id=53458

[themadscientist]

Oh snap! I just saw where you live. Dale City guy here! Enjoying that snow?

I am all for standalones. I don't like piggybacks. I ran them when there was no choice and I will run one if I'm on the cheap and it's my motor on the line, but I never recommend them to others if they are going for more than 25% over stock power. Others will disagree and that's fine, I have no ego hangup, I just get scared piggybacking above that. I fried an ECU with an SAFC.

If you are on a tight budget and are learning, I would suggest you shoot for a clean running tight (not tyte, tight, as in good compression) motor. A 200hp motor that runs beats a 400hp motor that doesn't.

[Tru180Kid]

This snow BLOWS i couldnt even go have fun, Are you from the NOVA area too? i noticed you said TYTE...which happens to be my license plate!

[themadscientist]

Gar-field high, class of 91'. I'm old i know, shut up or I'll hit you with my cane.

The license plate on my old Supra was GREDDY. My 180's is 1800 to show people it isn't an SR20

[Tru180Kid]

91 lol no prob gramps!!

I'm hylton high class of 06 I have the black turbo fastback says S13 TYTEshe's my lil biznich!

[themadscientist]

I remember when there was nothing but woods where your high school now stands. That road out front was a dark deserted ribbon of tar we would tear up at night. Ah memories.

[Tru180Kid]

Heh Spriggd Rd,I used to have some fun when we got out of school we tear it up but as u know it was 1 lane back then now it's jus causing all types of trouble being 2 lanes

[themadscientist]

You know Opal lane, off of Spriggs? that street sign is at least the third sign they put up. I own the original two.

[Tru180Kid]

Haha I haven't aquired my own street sign yet but a bunch if my friends have....maybe it's a Woodbridge thing!

[themadscientist]

I think it's a dumb kid thing. Enjoy your youth, just don't get caught enjoying it. I know how much those Montclair mailboxes cost. Guess how.

I see on google maps there is a "Silvia Loop" in Lake Ridge off the parkway. I wonder if they have a sign. Just thinking out loud.

Have you tried drifting the Potomac Mills parking lot when they are snow closed? I could get away with it, you probably can't these days. Nobody knew what drifting was in 1989 so nobody cared that I was sliding around the light pole snow piles.
