i have a few ? if you dont mind to answer okay i am going to be running about 6-7 pounds of boost so is it okay to run vortch fmu? with 440 dsm injectors and what piggyback do i need to use? if i even need it . and has anyone did this set up how did it run?

 

Ditch the fmu because it is crap imo. Run the 440cc injectors plus an ecu program like turboedit, chrome, etc Or you could convert to OBD1 and run Hondata or Neptune.

I would just steer clear or the fmu becuase there are much better options out there. Here is some light reading material.

could i use a vafc or safc and the injectors and be okay?

 

Do a search because there is more info on that than I can type in this post

For around the same price you can get your ECU chipped and socketed for use with Turboedit (OBD 0) or Crome, Uberdata and Neptune (OBD 1).

Here is something that I posted on a few forums about Crome. Add $40-$80 for a set of DSM 450's which are good for 290-320 WHP. And $79, $89 or $99 for a 190lph, 255lph, or 255lph HP Walbro fuel pump.

quote from www.pgmfi.org
Crome (Cui's ROM Editor) is ROMEditor that John Cui wrote. Its main feature that differentiates itself from other ROMEditors is that it supports the use of Java Script to control it and implement new features. The Crome Script API allows you to extend the capabilites of the editor with relative ease. People have already written many scripts for Crome, most of which can be found on the PGMFI Source Forge page.

Crome is available in 3 levels...CromeFREE which is free, CromePRO which is $149 and has several added features, and CromeDEALER which can be used commercially to make money and has several features available only to CromeDEALER. Some of the features that CromePRO has which are worth mentioning are as follows: integrated datalogging with replay feature, knock logging, and auto-tune (few bugs reported). A few other notable features are in the making such as live auto tuning. Crome is also very user friendly, and setting it up for real time tuning with Ostrich and datalogging is very easy.

GENERAL ECU CHIPPING INFO

Here is a list that I have posted several times which covers the basic pieces of equipment you'll need for DIY ECU chipping and tuning. You'll want to have a laptop to use in the car or at least be able to borrow one from a friend. The prices below do not include shipping and handling.

BARE ESSENTIALS
$$$ - laptop
$15 - ECU chipping/socketing supplies: moates.net "UBER 1" kit
$25-$75 - ECU socketing: moates.net does installation services as well as others on the net
$55-$85 - EPROM burner: ebay.com "Willem Enhanced" or moates.net "BURN 1"
$10-$45 - datalogging cable: Nokia or most cell phone cables, superdroids cable, moates.net Hulog

That covers the basics...all you need are some larger injectors and a fuel pump that can support your power goals. You can download CromeFREE or Uberdata and use those to change fuel, timing, and other options like VTEC x-over, disable O2 sensor and much more. You ECU can be made datalog-capable with the addition of a cable to your ECU's CN2 port. You can use a Nokia cell phone cable, any datalog proven cell phone cable, a superdroids cable, or the moates.net hulog. Before getting your ECU chipped find out what datalogging cable setup you wantto go with. Have the person socketing yoru ECU solder in the wiring or pin header into CN2 at the same time the ECU is being socketed. Just make sure you tell them what wires go to which CN2 pin location.

OPTIONAL ITEMS
$300-$330 - wideband setup: either a Innovate LM1 or PLX300 (DO NOT get a Zeitronix Zt-2).
$175 - Ostrich emulator: allows for real time tuning
$149 - Crome users upgrade from CromeFREE to CromePRO

The wideband is a good thing to have if you plan on tuning your own car. You can either buy one or borrow one from a friend, or just use the one that your tuner has atthe dyno shop. You'll want to stay away from the Zeitronix due to the nature of it's O2 sensor voltage which is parabolic as opposed to other wideband types which are linear. This difference makes the Zeitronix hard to setup for use with Crome and Uberdata, which is why they are still not supported by either one. The Innovate LM1 has it's own datalogging software. This is good if you want to use CromeFREE which does not have integrated datalogging (CromePRO does though). You may still have to buy a few pieces of hardware to be able to use the LM1's datalogging software. The PLX 300 does not come with any datalogging software so you must use it from within your EMS. AFAIK you wont be able to use the PLX300 with CromeFREE since that level of Crome doesn't have datalogging. IMO the $149 I spent to get CromePRO was well worth it to be able to datalog and <u>auto-tune</u> with Crome.</TD></TR></TABLE>

 

thanks for the help
