D16Z6si

Hey,

I have a couple of questions with regards to chipping my D16Z6 ('95 Si). I have an IHI RHB5 running at ~8PSI with and FMU, stock injectors and a stock fuel pump. I'd like to get a set of 450cc DSM injectors and a "tuned" chip that'll be made for my boosted engine.

First of all, if I get the 1G DSM 450cc injectors, should I get the "blue-tops" or it doesn't make any difference? Will I need a resistor box? If so, then what Honda (or other) car should I pull it out of @ the scrap yard? (Year/Make/Model) (I prefer to get a "resistor-box" over making the resitors myself).

Secondly, if I get the 450cc's and the "boosted" chip, will I still need to be running an FMU, or will the chip and the injectors provide the fuel under the boost?

Will my stock fuel pump be good enough for the 450cc's and the chip, or do I have to upgrade it to a high-flow one?

How much is a burner for chips for my ECU?
(What type of ECU do I have anyways on the D16Z6 SOHC VTEC? P28?). Which burner should I get? Are the chips re-usable, or can they be burned only once?

I'd like to also get ECU Control. Will it work with my ECU? Where should I get the hardware? (what is the type/model number? From which site?)... Is it worth it to have one?


Thanks in advance for all of the answers... I'll post the pics of my setup as soon as I organize all of the pictures that I took during my install...

yes peter.. you can ditch the FMU if u get 450cc's and a "boost chip".

yes your stock fuel pump will be able to supply enough fuel for these injectors up to around 12psi.

burner will probably cost around 200 for everything you need. Some chips aren't re-usable (CD-R kinda) and are cheaper then the ones that are reusable (CD-RW kind).

ECU control? im not sure.

read this post.

ps. still over heating??

I'm buying the "Max233 (AD233AK)" thingy to run ECUcontrol. Is it just plug and play, like in the pictures (www.ecucontrol.com), or do I need to have a "special" program on the Chip in order for it to output data to the serial port?

When I get the "boosted" chip, can I ditch the "Missing Link"? <---- since it blocks off all of the boost from the MAP Sensor.

Yep, the car is still overheating... I think that it might be because it's running too rich (or too lean) with the FMU.

Are there any places that could hook me up with an ECU, burn a program (.bin file) that I'll bring and a sell me a ZIF Socket in the GTA?

you have to have a ghettodyne chip with ecu controll enabled.

And is that just a "line of code" that has to be added to the "burned" chip?

Can anyone post info on how that can be done?


Can someone answer this? :

Eh, not that easy...it's much more than a "line of code". also, in your previous post, you mentioned that you're using a P28 (ODB1) ECU, right? Ghettodyne only works on the PM6 (88-91 CRX Si). You're going to have to look for other options for boost management.

uberteg.... same thing but for obd1 tegs, ,works w/ obd1 civics too.

I'm sorry to sound lame, but is Uberteg the same kind of tool as Ghettodyne? (modding the air/fuel rations and timing)...?

zac

Ghettodyne and Uberteg (Uberchip) are both ROMeditors...they let you open view the data stored in the ECU's code in a human-friendly/editable format. Both Ghettodyne and Uberteg use modified programs that add extra functionality, specifically, expanded fuel/ignition tables that allow positive manifold pressures (forced induction).

That clears up a few things for me. Which one is better to use with a P28?

Also, do I have to change 2 chips, or just one while I'l "chipping" a P28?

What's the best write-up for "chipping" a P28?
