how to control 450cc injectors?
 

Hi, how's everyone? I have an 86 CRX with a DOHC ZC. I'm going turbo(IHI-RHB5 off a Subaru). I still haven't run it yet. I purchased some correct inject 450cc from Tuner Toys to avoid FMU. I heard that I'll be running rich in just bolting them on. So my question is: What options do I have in controlling these injectors? I've heard of Apex VAFC, Hondata,etc... I'm on a budget and wanted to know which do you recommend? I'm new on turbo,still learning, and that's why I need your help. Any recommendations greatly appreciated. Also, do I need high pressure fuel pump? Mine's external, any recommendations? How about pressure regulator? THANKS!!!!!!!

FAG, oops I mean FAQ, check the FAQ. you will need some sort of control device to scale down the output of the 450s, espicially at idel

Re:how to control 450cc injectors?
 

afc, smc, trailer park afc, hondata, uberdata, turbo edit, you have many choices, it all depends on how much you want to spend, and how much boost you plan on running. read the FAQ in the 'engine management' section.

I'm thinking on getting APEX SAFC. DO you think I still need a high pressure fuel pump or will stock one work? How about pressure regulator? I'm planning on running 7psi. Maybe 10 later on. THANKS!!!!

Re:how to control 450cc injectors?
 

450s with a SAFC will be enough for 7-9 psi. no fmu, no badass fuel pump, etc. The only reason you should replace your fuel pump is if you are worried about your stock fuel pump taking a ---- under the increased fuel demand of the new injectors.

86, is that obd0 or pre-obd? If you are obd0, look into turboedit since you are on a budget. But if you go down that path, get ready to do a lot of reading before you get started. If you are in a hurry, hack it.

Re:how to control 450cc injectors?
 

obd 0 is pre obd

Re:how to control 450cc injectors?
 

obd 0 is pre obd

yep

Re:how to control 450cc injectors?
 

So is obd0 harder to work with? Will S-AFC work like in obd1 or different? Can you give me an idea of what to expect as in upgrades to be done or mods? I know it's harder cause it's an old crx, and parts are harder to find and performance parts as well. But I love my ride. Owned it for 6 yrs now. It deserves an upgrade. THANKS!!!

Re:how to control 450cc injectors?
 

since you're obd0, you can chip your ecu and use turbo edit to tune it, the easiest way to explain it is that it's like hondata. all you'll have to do is buy the parts to socket your ecu (about 10 bucks) and socket it, or have some one on here do it for you for a couple bucks, if you know nothing about the program and tuning it you can have some one burn a chip for you for a couple bucks, grand total 20-50 dollars. or you can actually buy a chip burner for about 70 bucks and figure out how to use the software (it's free) and burn your own chips and be able to tune it accordingly, either way, you still only pay a little over 100 bucks, which is less than a used afc and 100 times better. if you're interested in this, you need to start reading like d16 tuner said, there is a sticky thread dedicated just to turbo edit at the top of the page, once you get the basics, people will help you work out the kinks, but like he said, if you're in a hurry, just get an afc, cause it's easy and you don't have take the time to learn about turbo edit, it's up to you, but you would thank your self for learning turbo edit :-\

go to j.davis ;)
ask teg for details

Re:how to control 450cc injectors?
 

I really appreciate your help for the info. I'm really interested in learning about TurboEdit.So what can I do to start? I mean, can I buy a chip programmer,a programmable chip, download TurboEdit program and learn from there? Is it easy to understand? Cause I'm no computer wiz, but I can handle a computer OK. Where can I buy the parts? This is my first boost job and I want to do it right. Will TurboEdit guide me through? Or do you think I should go AFC and then learn TurboEdit and upgrade when I'm ready? THANKS!!!!

Re:how to control 450cc injectors?
 

The AFC hack is pretty much plug and play; if you want boost like RIGHT NOW you'll need to go that route. People on Ebay are always buying SAFCs for outrageous prices so you can always sell it later. TurboEdit is very popular, mainly because J.Parker takes pride in his work and has put together a very polished program. I'm using Uberdata in my obd1 civic. I think chipping the ecu is the only decent solution in the long run. Check out the Turboedit sticky and engine management faq above and go from there.

Re:how to control 450cc injectors?
 

OK. For now I'm planning on going afc. But I'm still gonna learn turbo edit and purchase the necessary hardware. Then I'll take it from there. Now another simple question. My timing is vacuum pressured, on distributor. Will safc work properly? Will the wiring bolt up on my ECU? I saw an old SAFC from APEX with no digital display, just tuning knobs for sale on E-BAY. They're like 5 knobs with 1600RPM increments. Are these any good? Or should I get the newer SAFC or SAFC2? THANKS!!!!! I also forgot to mention I'm planning on installing those 450 cc correct-inject injectors from Tuner Toys. No hotwire thing. Will that affect afc? THANKS AGAIN!!!

Re:how to control 450cc injectors?
 

if you tune the Safc then it will work on your car also yes it will wire to your ecu as long as you have a map sensor which you probably do have. get the digital safc's if you can get a deal on a newer one go for it but any one of the blue digital ones will work and be easier to tune. also the tuner toys injectors will work with the Safc. if you need some info on hooking up the Safc and the settings check out www.thermal99.com he has a good detailed write up on the Safc hookup and settings. Also turboedit is easy when you just do some reading and look at others results I learned a great deal in a short bit of time. Also WILL do you burn chips?
