Boost w/ Ghettodyne & ZC
 

Has anyone here successfully run a boosted motor with a Ghettodyne Programmed chip? What about a ZC motor. If you have, how many PSI are u running and what other fuel management do you have?

Re:Boost w/ Ghettodyne & ZC
 

I'm running a d16a6 with a programmed chip. The binary file I'm using is from George, so it's in the same neighborhood as what you're speaking. It allows 450cc injectors, no check engine light (CEL), and it retards the timing 1.0 degree per psi and gives rich fuel up to 6-7 psi (from what I've seen). Could use just a hair more up top if you were running higher boost. The ZC can also run off this, but I think maybe a tad more fuel.

Re:Boost w/ Ghettodyne & ZC
 

i'm still unclear wether you need to run any other hack along with the program. would it eliminate the need for my smc? so all I would have would be the georgehack, and my 450's?

Re:Boost w/ Ghettodyne & ZC
 

wouldn't your MAP sensor freak out at that psi? if yes, then how are u telling the ghetto chip the psi?

Re:Boost w/ Ghettodyne & ZC
 

The chip was programmed to ignore the MAP sensor, so there's no CEL. I think what it really does, is it cuts the voltage (like the AFC)...

There's nothing else involved except the 450cc, and the dang chip. Life can treat you good sometimes. LOL ;)

Re:Boost w/ Ghettodyne & ZC
 

where did you get your chip? did you burn it your self? i'm right up the road from you and all i need for my install is an afc (short on cash right now). i've got my 450's, if you can burn me a chip we can do my install (i emailed you a couple of weeks ago). i don't expect you to burn me one for free or any thing, but i'm sure it would be cheaper than an afc right now.

Re:Boost w/ Ghettodyne & ZC
 

What would you have to do to modify it to use a GM 2 or 3 Bar MAP Sensor? Anybody done this?

Re:Boost w/ Ghettodyne & ZC
 

Reformat the ECU's maps to accomodate the 2 bar scaling. I wouldn't care to try the 3 bar, though. You have too much loss of resolution on the input signal with the already muddy signal of the 3 bar + dirtying the waters further with an AFC hack.

Re:Boost w/ Ghettodyne & ZC
 

the chips are ATMEL 29c256 flash chips that I purchased.. can use them over and over... THEY COME BLANK.

and I've got an eprom programmer (burner) to burn binary files to the chips.. so I was lucky enough to know/run into George and Joseph here. Using the 91pm6georgehack file which I think george made and maybe Joseph modified?...

projekteg, I could give you a chip for say 10 bucks since we live close to eachother... with that file burned on. Remember, you have to desolder the stock rom out of the ECU, and that takes a little time and patience. Then put in a ZIF socket... see below

- 28 pin socket EEPROM socket (Got mine at www.digikey.com for $6.50, part number: A347-ND)

and you solder in the zif socket.. makes putting in chips a breeze. Heck, I could even modify your computer for you if you want.. purchase that zif socket, and I'll meet up with you sometime and I can take out your stock eprom and put the zif in for you... I'll do everything for 20 bucks if you want.

Re:Boost w/ Ghettodyne & ZC
 

okay so i have a zc also and am wondering about this setup..i have almost all my turbo pieces together but im looking for an afc and 450's. so with this chip i dont have to do the afc hack? and can this chip be put into a pg7 ecu? thats the 88-89 integra ecu. and what about more boost. i want to run around 9 pounds and then at the track with better gas i want to run 10-11. is that possible with the chip or should i stick with my plan and go with the afc?

Re:Boost w/ Ghettodyne & ZC
 

ok ok ok... wait a second. Personally i have never looked into a ghettodyne. But I have a question. If the chip is programmed to ignore the MAP sensor then how does the chip know what fuel curves to use? What is telling the chip what boost levels are???

Re:Boost w/ Ghettodyne & ZC
 

Reread this thread. Where does it suggest the MAP sensor is ignored?

Re:Boost w/ Ghettodyne & ZC
 

actually, I said that, but directly after I said "I think what it really does, is it cuts the voltage (like the AFC)..."

so,, oops. Sorry If I mislead anybody with saying that..

Re:Boost w/ Ghettodyne & ZC
 

so just so im clear u got a pm6 with the george hack and 450 cc injectors for engine management and notin else?? does it retard the timing and kill the cell or does it also increaase fuel pressures with boost? Do u still have to run ressistors on the injectors with the george hack bin?

would help if yould clear things up, thanks man

Re:Boost w/ Ghettodyne & ZC
 

If you have a car running a PM6 ECU now, all you need are 450cc injectors, the chip being talked about, AND SOME WAY OF TUNING IT. I suggest either an AFC or a chip burner, an edition of Ghettodyne will be out soon supporting it from what little elves tell me so a chip burner would not only be cheaper, it might be a lot better.

If you don't have a car running a PM6 ECU, you need to ask yourself what a car with a PM6 has that yours doesn't, and that answers all your other Q's.

Re:Boost w/ Ghettodyne & ZC
 

well the car im running is a 91 rex si with a pm6 the only real question i got is does this file support just my timing/spark needs or does it also increase my fuel pressure as the map reads higer boost. I just basicly just want to know if u guies are running fmu's etc. or not? Sorry if this is a stupid quesion im new to hondas

Re:Boost w/ Ghettodyne & ZC
 

the chipped ecu wont control fuel pressure.

Re:Boost w/ Ghettodyne & ZC
 

the chip's long arms reach out to those lonely 450cc injectors knowing their needs,.. feeling the power... the chip decides it's time to control them.

Re:Boost w/ Ghettodyne & ZC
 

The chipped ECU also reluctantly controls your ignition. It would rather vacation in the Bahamas, but alas...

Re:Boost w/ Ghettodyne & ZC
 

is it for obd1? i'm not sure what ecu i have, i beleive it's a p30 (93 integra ls). could this chip work for me or is it only sohc?

Re:Boost w/ Ghettodyne & ZC
 

hey MR_DR_PEP i was just a lil confused after chekin out yer site. I didnt see any pumps/fums etc wht r u using for fuel management if the george hack doesnt controll fuel/boost ratios?

Re:Boost w/ Ghettodyne & ZC
 

projekteg: OBD1 PR4 if LS, P61 if GS-R. Look into Uberchips is my recommendation.

whaaat: Read this and then reread this thread.

Re:Boost w/ Ghettodyne & ZC
 

J Davis you are the man! this thread is getting me excited. I have a chip burner on the way, and a pm6 and ps9(ex auto) both waiting for me to slap chips in. i've noticed on your webpage that you have v2.0 of ghettodyne. is this still in the testing stage? i've been checking the pgmfi board alot, but mostly just reading and trying to learn. i've downloaded the georgehack, but it won't open in ghettodyne, so what do I open it with, a hex editor? keep the info coming.

Re:Boost w/ Ghettodyne & ZC
 

Hi guys,

I just have a little question about ghettodyne chip.

does the chip ajust the mixture with the psi of boost??

I mean if i install a chip on a 8 psi turbo and on a 5 psi turbo, does the 5psi engine will run lean?

and i would like to know how can i modify the setting because i'm gonna get a chip and would like to tune it with a wide band.

Thanks

Re:Boost w/ Ghettodyne & ZC
 

Get the regular, naturally aspirated version of Ghettodyne and look at it, civic1990si. That is what it does now, and what it will do for boost as soon as a few bugs are ironed out.

turbowagonman: 2.0 still has bugs. 2.2 is being beta tested now, and is based on George's code based "AFC hack." You want a copy of that? Go here:

Re:Boost w/ Ghettodyne & ZC
 

88 -89 PM6s end up controlling your car the same as a 90 - 91 PM6.. that's why it's a "PM6". The difference, however, is the hardware that is used to create the ECU. In the 88-89, the program used to control fuel and spark is located in a microcontroller which makes it difficult to "chip". It can be done, but if you don't have a background in being able to understand eletronics, you'll be better off just buying a 90 - 91 PM6. This generation of PM6 holds the program in an external 256K EEPROM. This is good for tuner because you just have to desolder the chip, drop in a socket, and drop in your own EEPROM. How quaint.
