Digi combo

Has anyone ever ran an RTek 1.7 or 1.8 with an apexi afc neo? What results did you get? IM thinking about this combo on a large street port until i can afford a powerfc and dyno time.

It will work, you should be fine just don't over do it with injectors. I had the 1.5 controller 550/680cc injectors I had a safc II and I was running just fine. One thing to remember when using a piggy back is when you take away fuel ignition is advancing, and you add more fuel the timing will retard more.

Well i was thinking about 1.7 because of the port ii will do. Ill be getting much morre fuel through there. I didnt think you can do bigger injectors on 1.5.

I ran RTEK 1.7 with a SAFC neo, 750cc secondaries on a SP S4TII. It worked, but I would suggest just buying a RTEK 2.1 and not dealing with the limitations of a safc.

I wasn't saying use the 1.5 I was saying that's how my set up was, on a 6 port tii. But your are going for 1.7 or 1.8 and the neo. You will have no problem. I would say go for it and save for a good standalone. Afm are horrible.

I know you were saying for me to buy it. I was just commenting on your set up. Right thats my plan exactly. The rtek 2.o sounds good for us s5 kids but its just too mch work on a little palm. I dont think i want to deal with it. Its limited also anyway. Im not gonna be running high boost at first. i just want to be aboe to drive it and break it in properly on the large ports i want to do. Ill wait till I save up enough for the pfc and upgraded turbo. Who makes afms?

No one makes afm's. It's better just to go with a map sensor or if you have a hot wire maf But I prefer map sensor, since if you pop off an inter-cooler piping you can still drive off to the side safely. Unlike when your motor completely shuts off and you cannot accelerate what so ever if you have and maf or afm.

Some people have had up to 400whp, to his or her own difference.

My engine is all stock. So I dont think I have any of the things you are talking about.

Yeah you'll be fine. I assume your going to put in the right size injectors correct. If so, your going to be barely playing with the neo. Put in a fuel pump to be safe, if you don't have one.

Ya ive already got a supra TT pump waiting to get dropped in. I wonder if i should do the 1.8 with the 720s all around for the sake of the large street port. And 400 is a lot of power. I only plan on getting to 320 330 or so.

If you have I would do a 720/1000cc combo. It's always better to have more fuel and take it away then to have no fuel and trying to add it. Also with the bigger pump your fuel pressure is going to raise a tad, since more pressure. (You should already know this)

But x4 720 should get you to 330rwhp. I ran 550/680 it held up to a decent amount of boost on the 1.5 chip. But you should know that the only difference between 1.5, 1.7,1.8 is just the injector sizing. Both timing maps will be stock. So if you can if you have bigger injectors, you can "add fuel" with the neo and the timing will retard since you have a large street port. Kinda get what I'm saying?

got it. i know the timing is stock with the 1.xs. Are you saying that te large street posrt will retard mt timing? That doesnt make sence to me. I know the rteks retard timing once the boost gets over stock press. Is this what you are talking about?

Well stock ecu will only compenstate for 10psi and will have a locked timing all the way up. With the neo, you will want to "add" fuel so that way the ignition is retarding then advancing the timing. The larger street port will effect it a bit, but you should be fine until your standalone.

A tuner told me no to waste my money on a neo. Said its garbage. Not sure why he said that.

for that much money thrown away, you could have a proper stand alone ecu.

i would simply wait to have the money to buy a PFC, and keep the stock turbo during break-in even with port work.

this way you'll have a decent running base map to get you point a to b as needed while you break in the motor. and then once broken in you can put your larger turbo in and tune for the power you want.

i was thinking about this. but the whole reason i even asked these was because im getting the neo for $200. Other wise I could just run the large streetport with everything stock and just not boost it till it breaks in. It will break in a lot sooner than i get the cash for the ecu. idk. Seems to be a lot of options. Im so indecisive at times. lol

What about running an fcon with the rtek upgrade? will they interfere with eachother since they both have fcd?

you fail to understand the concept of the rtec.

the fcon, neo, and others modify the AFM signal +/- every couple of rpms every couple of points.

the rtec does the same.

but im not doing rtek 2.0. Its 1.7 or .8. How do they add fuel on their own without something to control fuel? If they can do this can they deal with a large steetport?

How much money are you spending exactly? Because you need to tally up how much your spending to how much is needed for the upgraded part.

I mean if your paying about $550 for the neo and rtek, why not source for a decent standalone for that price? I thought you had these parts laying around.

what the hell did you just say?

If they can do this can they deal with a large steetport?
yes. but then again, why stick with an rtec when you are putting a band aid on the already old and tired electronics and then slapping another band aid on top of it?
ALL the fc's use the air flow meter to determine how much fuel to inject. you end up maxing out the airflow meter when you run it past what its designed for, and thats when you add more fuel. but... at this point, the airflow meter becomes a restriction.

seriously people. the rtek is not a godsend or anything. you can come spending about the SAME amount of money as if you went to a stand alone ems, and then sold off the stock ****.

Im getting the neo for half the price.
