I have been trying to get my conversion done in time for Okteenerfest. I have run up against a brick wall and just cant seem to figure out what i am doing wrong.
If anyone can help me by looking at my tune files or providing insight it will be very much appreciated. I can get th car to idle but nothing beyond that. Any use of the throttle is less than impressive and almost useless. Meaning it bogs down and does not accelerate at all. I have no clue what i am missing. 2056 with new low impeadance injectors. Bosch Wideband O2 sensor. Really need some suggestions. Not sure if i can post the tune files here. But will try. |

Thanks for the detailed follow-up James. We basically agree on everything important. MS and others can be excellent FI solutions for those willing to pay the price.
100% disagree with the comment on the D-Jet terminals. Lets forget this myth it has no substance. Greenwood promotes a beyond-extremist perspective if that is your source, he has provided nothing to back up his claims. Perhaps on paper, in a lab setting under forensic evaluation they are not the most optimal engineering solution and 100% agree that L-Jet style hardware is a significant technical improvement towards connectivity, but that does not make the D-Jet terminals fatally flawed. No 914s or other D-Jet cars have burned to the ground because of this terminal. How many D-Jet cars still have their original harnesses using those 45 year old terminals? Every 914 I have ever owned has its original harness and several of those cars I drove daily for many years with never a related fault. VWs, MBs, Volvo's - a significant number of cars used D-Jet around the world and continue to use it and its hardware to this day without issue. AS you mention, our D-Jets on stock engines are perfectly suitable solutions for what they are, I would argue that they were not designed to provide the level of precision that newer digital based FI systems are capable of, nor do our stock engines demand that level of precision. So the higher precisoin is more of a novelty only, where it is not essential to the needs of the engine. Because they can be so sophisticated to set-up, custom fit and calibrate, it is disheartening to see some that attempt the conversion not be successful or not successful without extreme dedication and sacrifice - the effort and cost needed can be a significant price to pay. The conversions can be and are done, but at what cost in time and materials? The most expensive part of the D-Jet is the MPS and rebuilts are available for $300. and its a bolt in solution. If folks want to go to the trouble of an FI conversion, or need to because of engine mods, they just need to be aware of the full impacts of that decision - either way they have my full support as long as they are fully informed. |
