Which Engine Management

[NSRacer]

First let me begin by briefly introducing myself... My name is David De Anda and I'm a moderator over at the SR20 forums (sr20deforum.com). I had a '98 Sentra SE turbo that put down 333hp 312 ft/lbs of torque to the wheels (not to brag or anything ) and also a '97 200SX Drag Car (that actually never made it anywhere because we lost our sponsorship).. Anyway, I now own a '72 510 (that I'll probably be selling) with an S13 DET (which will probably be taken out and replaced with a nitroused KA) and a '95 S14. Good enough...

Now, my question is in regards to engine management: In my Sentra I use a JWT ECU and it worked great; in the 200 I used F.A.S.T. (formerly known as SpeedPro) and it worked great too. Now, I have an S13 DET that I'd like to swap into my S14 but, my problem is that the engine didn't come with stock harness, MAF, ECU, etc. (no stock wiring) but, rather it came with an Accel DFI running off of a RWD N/A SR distributor (no CAS and no stock coilpacks). I've never used the DFI and I'm wondering how well it will do. I want the S14 to be streetable and still have AC (since I'm a fat bastard that lives in AZ) because the car will be driven daily. I've also been debating on removing the DFI and getting an SDS (just because it's so simple) or just ditching all the standalone stuff, sourcing a harness and ECU and just running a JWT unit. I know that there's a few of you that have had some pretty good experience (and seem pretty knowledgeable too) so that's why I'm asking. I don't ask the SR20 forums simply because they're a bit more JWT biased (a lot of the original SE-R list is on there). What I'm seeing is that most of the FWD community is sticking to JWT while most of the RWD people are doing their own thing... Well, that's long enough so I'll shut up now

BTW, since I know it's going to be asked (even though it doesn't have very much relevance) I'll be running a T3/T04E (.82 A/R eh with a stg 3 wheel / .60 ch with a 60 trim wheel) on a ProTech manifold, and running MSD 72lb injectors.

Thanks!

so your asking if the accel DFI is a good unit? yes, of course it is ( i dont think thats what your asking though)...but i do not know anyone who is running it w/ an SR....

There are so many varying opinions on which standalone is the 'best'.....Personally i dont like sds, and prefer Electromotive over anything, and haltech is a nice unit...

for simplicity's sake, the power FC is a very good option (power fc pro for map sensor option), but you said you dont have a harness, so a plug and play ecu might not help you....

Im not a fan of the JWT, and even with that said, i have never heard anythying positive about their 72lbs injector setup.....

well im not sure what your question is...i see your background and read the post, but all i can come up with is the accel dfi question, and like i said, ive never heard of it used with an sr20det : \

[NSRacer]

Do you have any experience with the DFI? I've never used it before so I don't know how good it is and I can't find very much info on it. I can find some on Accel's new version of the DFI (version 7) but, not on version 6 (which is what I have). What do you think of the distrubutor/coil combo over CAS/Coilpacks? What I really want to know is if it's streetable and if there's any output for an AC fast idle.... Yea, I know, but it's freakin hot in AZ Thanks man..

I have never used the DFI, but i believe my friend charlie was using it on his race civic, there might be some info here http://www.b20vtec.com.....

i dont like the distributer coil combo, which is one reason i dont like the JWT setup, yes, it is fine for most setups, and street applications, but in the world of high horsepower etc., the coilpacks are a better option...I like the coilpacks, and upgrades for the coilpacks, and will produce better spark when you start upgrading fuel etc for higher hp setups, but for most street setups the coils/distributer is fine.

the a/c shouldnt make a difference...

i know a lot of the muscle car guys around here use the dfi, but i dont see it much on imports, i think its more popular in the domestic scene......summitracing.com might have info on the version 6.

Pretty much same thing I was thinking... I guess I can throw the DFI in and see how it does and if worse comes to worse I guess I can sell it and look for a TEC II or something.... Thanks man...

[Imissmyturbo]

Where can you get a power FC Pro? All the places I have seen don't list anything about them. Also how much more are they compaired to the Power FC?

[Cyberkreig]

So is the Electromotive a PnP unit? I definatly want fine control, but screw making my own harness.

[1bad180sx]

The only one that is PnP is the Power FC. Sometimes making your own harness, cutting the apron strings, welding something custom, etc... is required.

Electromotive Tec II is good, Tec III is better. Tec II is much cheaper, however.

There are other alternatives. Haltech is an awesome system, designed by some of the best in the business. I would like one, but price is a factor for me.

The Wolf 3d 4.0 is also a great computer. There is a lot of negativity about the 3.0 out on the internet... it didn't have so many features, but the 4.0 has fixed all the old problems and is now on par with other world class standalone systems.

SDS is ok, but has no features like these other's have... Hence "Simple Digital Systems" - It's supposed to be easy. It doesn't allow for a laptop hookup for Datalogging and tuning (unless I'm greatly mistaken, but everybody I know with SDS can't do it) For the money, I'd go with the wolf.

I'm stuck here trying to decide what to use myself. I have several friends with Power FC's, a couple SDS, one with Wolf3d.... So I can find help on any of the three. I've also got maps for the Power FC and the Wolf3d, so It's really a toss up between them.

I like the Power FC because the base map is really good, and an excellent place to start tuning from.

I like the Wolf because it has outputs and datalogging built in... I just plug it into a PC, and Voila... It can control other devices with the outputs, such as electric fans, water injection (which I am using already), whatever else you can dream up....

Sounds like I'm already sold. I think I'm getting the wolf.

Where can you get the Wolf here in the U.S.?
