What are you talking about more parts and a ECU? s**t foO, I'm running a PR4 ecu off a 90-91 Integra LS/GS for my d16z6
tuned with a apexi safc2 and ghettoed out with some fish tank parts so my MAP sensor won't see my boost. You can do it!
car just wont accept boost
- Thread starter BoostinEX
- Start date

Sell the SAFC and get a chipped ecu
That's what I'll be doing soon
I got a virgin p28 a obd1 conversion and a wide band. All I need now is a cheap lab top but I'll be tuned with crome soon.but for the time being a apexi SAFC works fine. I've never really had a problem with the tune it's given me but the unit itself sucks. The screen went out a few months after I installed it
you too but the OP said he cant afford an ecu. if he sold his afc while its in good condition, and bought a used ecu , and a conversion harness it wont cost him too much money to have a proper setup.
chipped ecu is mad cheap... sell that apexi
buy a p28 for 80 bucks... have it chipped and tuned.. I got a chipped p28 + a street tune for 350

i dont think its the map sensor.. if hes barely going into boost then i dont think he needs a bigger map sensor
damn good price. people around here want almost 400 to dyno tune a p28 w/crome & only like 150 to tune a hondata unit.
its the map. if you get a chipped ecu, it'll read the boost from the map and you won't need a missing link or check valve. if you try and run the apexi, you'll need some kind of map fix. and like someone said, if your shop can't figure this out... man... ur in trouble. chekc out phearable.net you can get a decent base mapped ecu and harness for about what you can sell that afc for.
well I tryed to tell them the AFC isnt a good idea and they clamed to have tuned alot of cars with them, including a turbo civic that works at the shop, but I'm not going to pay for the installation of it, f**k em. My Dad ended up getting pretty mad about the situation and so he talked with the owner of the shop. According to the owner the internal wastegate wont go lower then 10 psi so thats why the car runs funny, it doesnt like that much boost. Weither or not this is the cause its what he told my Dad. So my dad went ahead and ordered up a new (rebuilt) turbo and they are going to install it for free. So being out 400 more bucks sucks, but if it is what you guys are saying, the map sensor, then we dont have to pay for the turbo (this is if the car still doesnt run right after installation of the new turbo). I'm kinda bummed my Dad did that but he doesnt know anything about cars and was just trying to get my car the right parts to get driveable, which according to the owner of the shop, is a different turbo that can run lower psi.
Thanks for the help.. meanwhile school starts this week, and I dont have a car for work or school, this is going to be bad....

Better yet sell those wheels for some extra cash.

what ECU do you have right now? what year and model car is it.
if its a OBD1 ecu it can be chipped for under 50 bux. search around for it. also if obd1 chrome is free.? thats the tuning program used. you dont NEED hondata...yes its nice but chrome is free. and does everything hondata can do and i believe even more. sell the apexi crap and invest in getting your ECU chipped.
heres a dude that chips ECUs.

if you have already spend t2 grand on your car man go ahead and drop the 50-100 bux for this. your car will be much better than anything tunned with Apexi.
hmmm....your having trouble.....huh. personally i think you should of done your research and learned how to do compressor mapping and then done it your self. as of for this shop......i think you should of takin it to someone who knows what the f**k they are doin. as for me.....try pushin 26 pounds out of a gsr motor punched to 2.3 litres. helpfull little tid bits............
1. HONDA MOTORS DONT LIKE BOOST, bypass the map sensor (missin link, or stand alone ecm and cancel the signal) and brace the jackets of the block. except for solid deck blocks....oviously
2. stock honda wrist pins are prone to breakage under boost.........before adding boost upgrade the bottom end with a stroker kit or aftermarket stock replacements.
3. start saving for internals right away if the the block was not worked over. boost, even the standard 7-10 psi is hard on the rotating assembly of the motor (ie. crank, rods, bearings, pistons, piston pins, and so on.)
4. anything under 14 psi can safely use an internal wastegate.....as of yours not accepting anything lower than 10 is complete bullshit. you can make your wastegate open before you start even building boost. one thing that distroys motors is called boost creep. when an internal wastegate is too small for the amount of bypass gas trying to escape.....thus over boosting the motor
5. STAY AWAY FROM MOST "FUZZY" BOOST CONTROLERS!!!! opt for a greddy profec b, apexi avcr, and the best is innovative turbo systems (but very hard to use)
6. a stand alone ecu, or reprogramable chipped ecu is the best way to go. and the tuning should ONLY BE DONE BY SOMEONE WHO KNOWS WHAT THEY ARE DOING!!! apexi afcs, vafc2, and so on only can adjust the fuel map by a couple of percentages. boosted motors require more fuel since more air is being forced into the motor.
7. bigger injectors are a must, even if running a low boost. majority of people who boost end up building wanting more boost. 450cc injectors are damn good for low boost. most junk yards should have dsms laying around......jack them, they work wonders after a good soak in seafoam, or have them sent out and cleaned, adjusted and remapped for the correct cc's. if anyone is wondering.......im running 800cc jets
8. there are plenty of books and what not out there on turbocharging cars. i suggest you pick one up BEFORE you attempt this again. a good turbo kit or a high quality home built (pieced together) turbo kit is going to run you big bucks. parts arent cheap and sometimes you have to buy more s**t just to get it to work right or pay someone out the ass to put it in. ive done my own s**t except tune it......that was done at my boys shop whos turboed countless hondas.
sorry to hear about your fustration tho. but sometimes...........s**t happens
Get Hondata.
nah your not screwed......its just going to take pateints (spelling sucks), and to find someone to actually do it right the next time. my thought has always been do it right the first time and save youself the headaches and money problems. always do some looking around and research places and what parts EXACTLY that you will need.....that way you dont get any surprizes by the shop saying......ohhh well we cant do this cuz you need this part.....BULL s**t. if they knew what they were doing then they should know what to get befor hand. other words if you want to attempt this your self and learn a couple of things or four.....alot of us on here can prob help you out doing this....although it would take longer due to the internet....but its an option
