somewhitekid Posted June 11 Report Share Posted June 11 Been having trouble with staying at Target AFR when at idle. VE is around 30% with duty cycle at 1.1%. The injector deadtime table is correct according to the data sheet, but i doubt they were tested with link. I believe this is the cause of being so rich and not able to lower ms. The engine is a boosted H22 running on E85. Injectors are 1000cc from a Youtuber named Hunter Tuned. He admits they are quite inconsistent at lower ms, but are pretty good when they open up. My question is should i play with the deadtimes to try and get more realistic VE numbers? to forums.pclx to forumm.llgx Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 11 Report Share Posted June 11 Are they a modified injector? Is there a part number on them? What do you mean by "injectors will not go below 1.5ms"? Does it just stall if you reduce VE further? Your fuel density looks a little low for E85. Also your MAP sensor calibration is a bit odd for a omni 3bar, I usually see this quoted for the omni 3 bar: This calibration would result in quite a bit less fuel below 100Kpa compared to what you have now.

somewhitekid Posted June 12 Author Report Share Posted June 12 https://www.huntertuned.com/product/huntertuned-1000cc They are custom. There is a part number on the side. 0 280 158 117 Looks like a genuine Bosch injector. http://www.phearable.net/tech/omnipowermapsensorcalibrations.pdf I got the Map calibration from here. on the last page.

That part number comes back as 547cc/min so I suspect the spray pattern and atomisation is pretty shocking https://www.bosch-motorsport-shop.com.au/547cc-min-ev14-injector Quote Link to comment Share on other sites More sharing options...
somewhitekid Posted June 12 Author Report Share Posted June 12 Haha yeah. You get what you pay for. Need to get a better set from a more reputable company. Quote Link to comment Share on other sites More sharing options...
aerace_fab Posted June 12 Report Share Posted June 12 you will thank yourself later with good injectors. Confused 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 14 Report Share Posted June 14 I would try to validate that MAP sensor calibration somehow also, I dont have confidence in the data available. That phearable doc you linked to gives different results depending if you use the quoted transfer function or use the scale/offset given for the hondata. Then most other websites I could find with published data for "Omnipower 3bar MAP" gave something different again. At 0.5V there is 20-30kpa variation (or 100% error!) between the 4 different calibrations that I found. Even the Omnipowerusa.com website is wrong, they have the same 4bar calibration quoted on their webpage for 3bar, 4bar & 5bar sensors...
