Piggy-back Fuel Control/Chipped ECU Help

Post by **CA18Fastback** » Thu Apr 15, 2004 2:54 am

Hey everyone,After actually realizing that I can't afford a standalone right now, I am forced to look into using a stock harness and piggy-back fuel control. Unfortunately, since I have been looking at SDS and Microtech for so long I do not know what everyone is using to tune their engines as far as piggy-backs go.

How does this list sound?-stock harness-chipped ECU-z32 maf-SAFC or E-manage? Other?

If anyone has these parts to sell, please post here or e-mail me [email protected].

Also, can anyone here chip an ECU for me to run 720cc injectors and a z32 maf? I really want to get this car on the road in the next 2 weeks if possible.

anything else i need? Any opinions or personal experience are appreciated.Thanks!-Ian

you can get a stock ECU and E-Manage and use the map sensor to read once your stock AFM is maxed out or use a Z32 AFM. and you can run up to 550cc (but i have heard of others running larger on stock ecu w/ E Manage - i guess seach here, sxoc and freshalloy)

i would go with the emanage as you can controll ignition, atmospheric bov's and have datalogging etc..

Hey Ian,

I wouldn't dare settle for piggy backing with all the things you've done to this motor. Unfortunately, I just sold an SDS for $850, but I would seriously be leaning to some kind of standalone if I were you. I know budget is at stake, but you have to bend the rules and push the envelope or in this case the wallet and credit card a little more to achieve optimum results. I don't think you'll be all that fulfilled with a set of 550cc injectors. Just my $.02.......

$850, Dee??? Damn you! LOL jk. I truly cannot afford a standalone right now. My parents were gonna float me a loan but they can't do it and I still have to buy hotpipe, intake pipe, downpipe, test pipe, and get some custom work done PLUS tuning. Can I run my 720cc injectors on a chipped ecu or E-manage? If so, I'll probably do that. Does the e-manage use the maf or a map sensor? Do you have any harnesses, Dee? Or maybe a used SDS?

Any help is appreciated.-Ian

also, I dont think i'm going to "settle" for piggy-back it's just that I have to get this car on the road now. I can upgrade later when I get a diff turbo and make the parts I have designed

hehe, secrets secrets.

me too! we are in almost exactly the same boat, this is rediculous. i had my buget all worked out and then i got a bank error (no joke, this is the second time!) and came up $100 short. then my $106 head gasket source went belly up on me and i came up another $150 or so short. then i had to spend twice as much on an intercooler than i had planned, and it all went to hell. i would love a stand alone engine management system, and plan to get one as soon as i can, but for now i am in debt up to my armpits and will have to do the best i can with the safcII and my SWAT ecu.

i think if you are on a budget:

you can run up to 150% of the injectors that the ECU is mapped for so, if you got a ECU mapped for 550's then you can run up to ~850cc's.. and adding the Greddy MAP-sensor for MAP vs RPM based scaling of injector, timing, and airflow maps, its supposed to be better than RPM vs TPS.

but remember the E-Manage allows you to run additional injectors if needed and have individual fuel maps for those as well...

and real time map editing and datalogging the OE sensors with the Profec E-01 on board.

I'm gonna run SAFCII till I've got the dough for a Power FC. I'm not runny any crazy injectors or hp, so I'm not real worried about it.

Post by **CA19DET** » Thu Apr 15, 2004 2:54 am

yeah the SAFC II is great and will work fine, it too can handle 150% bigger injectors so you'll be safe with the 550's.

good luck

I have to get it back from the body shop first though. The guy has had it for a month and a half. I went and sat in it the night before last, just because I was having withdrawl. I've been driving my grandpa's jeep cherokee for the last 2 months and it's driving me up the wall. I hate SUV's...

can anyone here chip an ecu for me?

Post by **r34 gtr** » Thu Apr 15, 2004 2:54 am

someone on here is set up to do it i think. i know jezz is, just talk to him..he's around here somewhere.

do you think i can make close to 400whp on stock harness with chipped ecu, z32 maf, and safc II or e-manage? I already have pretty much everything else ready to go except for wiring and a bit of piping. Dee, your expertise is appreciated here. I know you stand behind SDS but I have college **** I gotta pay for coming this fall and I am just not making enough money to shell out $1300 or more for a system right now. I need, I repeat, NEEED to get this car on the road ASAP. Anyone got a stock harness? Someone e-mailed me and said they had a harness for sale but it was $300 with no ecu which seemed kinda steep.

PLEASE HELP ME !!!-Ian

i wouldnt trust 400whp to a piggyback system. i dont plan on making more than 300 and i dont like the idea of using the safcII. unfortunately i am in the same boat as you with the college junk so i too am lacking the funds for a stand alone. im not saying you cant, just that in my personal opinion it wouldnt be worth the risk. im not sure though, i might trust it to the e-manage, that looks like a pretty solid system.

Get the car on the road first. Make the 400hp later. I'm planning on less than 300hp (prob 250-275) so I'm not REAL concerned about using a piggyback. But I would like to have it make much more power later. Right now I want to get done with the motor and move on to the suspension.....

Hey RYAN!!! We still on for early this next week?? Need to know If I should fill the tank or not...

Post by **quest** » Thu Apr 15, 2004 2:54 am

another option. I plan to use perfectpower.com smt6 piggyback. Does fuel AND timing, but cost less than a safc. Needs laptop tho. Less hassle than emanage.Setup; z32 afm/550s on stock internals. First with a evoIII 16g/ custom mani. Later, I'll look to bigger injectors/20G, same mani.I've come accross a few sucessfully tuning their ca18det via smt6. They all like it alot. One posted here. Another ca/smt6 tuned is switching form his t3/t4 to a 16g (for more snappiness).

Post by **CA18Fastback** » Thu Apr 15, 2004 2:54 am

hey quest,how many people do you know of that use that on their CA's? It looks like a real nice system but prices arent listed. If I went that route should I get the SMT6-TURBO-KIT or the SMT6-USER-KIT cuz the turbo one comes with a 2.5bar map sensor so that would eliminate the maf, right? So if I got a stock harness and ECU with that SMT6 I should be good to go, right? I've got a few laptops at home that I can use.

-Ian

Post by **CA19DET** » Thu Apr 15, 2004 2:54 am

yeah the SMT6 and the 2.5 bar map sensor will eliminate the stock afm or at least retain it, and the ecu will switch to the map sensor once the MAF sensor is maxed out.

and i think ~400hp is ok on piggy backs, just not everyday driving at whatever boost is required to make 400hp, only with the right fuel & set up,...i woldn't trust 400hp to a SAFC II, i'll get the E-Manage or SMT6 so you could controll timing and can use a Map sensor and other features.. but most importantly TIMING controll.

Post by **r34 gtr** » Thu Apr 15, 2004 2:54 am

exactly the reason i will be tuning safe as hell. god i wish i could control timing. if you really wanted to be able to at least change how the engine automatically adjusts timing, you could get the MSD ignition with boost timing control. fot the price, the e-manage or smt6 is definately the best idea. i wish i had known about the smt6 before i got the safcII. anyway, we will see how it works, ill let you guys know.

That's just it, the CA18DET is very timing sensitive in the fact that it doesn't like too much and too little kills performance and raised temperatures. Just like you said, tune to be safe and the ecu will control your timing just fine. But fuel is all in your court.

Aaron, yes! We're either painting it today (Sat.) or early Sunday. Regardless it should be ready to take home by Wed. YEA!!!q

Post by **CA18Fastback** » Thu Apr 15, 2004 2:54 am

where can I order a SMT6 from? I checked the vendor lists on the site but it said that the page was down/missing. any ideas? trying to order it this week.

Thanks!-Ian

Post by **quest** » Thu Apr 15, 2004 2:54 am

try Ott's Performance in Oregon, email [email protected]let us know how it goes 4 u

Post by **CA18Fastback** » Thu Apr 15, 2004 2:54 am

which model of the system should I order? i know I want the 2.5bar map sensor so should I jsut get this one?

SMT6-TURBO-KIT 1 x SMT6 Box with injector driver1 x SMT Harness (Wiring Loom)1 x Map Sensor (2.5 Bar)

Do I need a special connector for the laptop? Anything else I need to order with it?

Thanks guys, I will hopefully be ordering today or tomorrow.-Ian

edit: i see that you can order accessories on the bottom of that page. what should I go with?
