if you're not mold sensitive then you may do fine driving around in a molded car w/o a musty odor, but lingering spores are still bad news and can slowly tear away at a healthy person's immune system and eventually make them sick or present other health problems. only way around it i see is a total strip down of the interior that includes removing dash and scrubbing down every nook and cranny ordinarily unreachable, heater box, vent ducts, etc. i'd just rather find a car that was well taken care of than to go to all of that total strip down trouble. |
Yeah I've never had that problem.

this is EXCELLENT! just what I was looking for. Megasquirt EFI has a similiar table, but not as much resolution. Looks like you have a 17x21 table, megasquirt is limited to 8x8 (on the AFR table) and 12x12 on the VE and spark advance tables. The bottom (X) axis is RPM. The only problem I have interpreting this is what the left (Y) axis is. In megasquirt, air is metered via a MAP (manifold air pressure) sensor, and displayed in KPA. As a rough guide, 0=engine off, 20=engine braking, 40-60=cruise, 60-80=uphill acceleration, and anything above that is hard acceleration (up to 100kpa, open atmosphere, higher with boost). The second graphic allows me to understand where the various points are. Very nice, thank you very much. Do you have any plans for singh grooves, or powre lynz? On my volvo, i plan on 11.5:1 compression, powre lynz and powre intake valves, singh grooves, larger exhaust valves, and Coil on Plug ignition. Hoping for 35 MPG on a 2900 pound car, out of a 2.1 SOHC engine. Again, thank you. |

Something similar is an ozone generator. They're not as cheap, but they can be rented. |

This is too funny. The EMS allows you to change what kind of units you like to view things with. I normally view my units in kPa because it's a very easy conversion to mmHg so I figured it would be more useful. But then I was told most tuners prefer PSI. Anyway, here it is in kPa. ** I should mention that no "normal engine" can run this lean. Most engines are designed in such a way that they can't run leaner than 16:1 w/out lean misfires. VTEC-E engines are an exception. https://suspendedhatch.thecarthing.co...-E_Options.gif I'm using the built in VTEC controls to control the VTEC-E. The VTEC controls are quite sophisticated with lots of hysterisis. https://suspendedhatch.thecarthing.co...EC_Options.gif Then I'm controlling VTEC with the Option Output. There's no hysterisis unfortunately, but it's not that critical since I'm usually at WOT at this point anyway. Alternatively I could use the N20 controls which have a lot of hysterisis, but I wasn't able to get them working for some reason. Quote:
Roller Wave Pistons I'd also have him modify the oil pump and do some head work. All of this is guaranteed to increase power as well as FE. I'm making good money now but it will take me a year or two to pay off my credit cards. Quote:

Interpolation and Resolution
All ECU's do that because that is part of the math of running an engine. There have to be very smooth transitions from one cell to another, especially with ignition timing; otherwise you'll feel rough spots, cutting out, and stumbling. I have to ask; what would the alternative to interpolation be? Stay one value until load and RPM change enough that they round you into the next cell? A standalone that did that would be junk. More resolution allows you to closely follow the VE table. All engines have their peculiar dips and surges in air flow. All VTEC motors have a dip in VE right before the VTEC crossover, then a very sudden surge. VTEC-E is no exception. You need to bend the fuel and ignition graph around these points. This results in better power, mileage, and drive-ability that you can feel and measure. You can imagine tuning like stretching a cover over a bumpy surface. The surface is the airflow into the engine across different RPM and load. The stiffness of the cover is your resolution. Low resolution is like trying to lay down sheet metal. High resolution is like laying down a silk blanket. At Idle, where a very small change in load and RPM is a very big change in the amount of air entering the engine, high resolution is absolutely critical to get it to idle smooth, to settle in without stalling after decelerating, to cope with changes in load ie headlights, radiator fan, blower motor. Each of these conditions should put you in a neighboring cell so you can have a different pulse-width and ignition timing advance. With low resolution you encounter many areas of the calibration where one cell is doing double duty for two different conditions. This is extremely annoying. You tune the car to the perfect AFR while driving uphill. Then it levels out and you find that you are running very rich. You lean it out, then you start climbing another hill and the engine starts bucking from lean misfires. You smack your forehead realizing you keep changing the same cells and you are forced to compromise (always on the rich side). |
Ah, I see what you're saying. The ecu can calculate and use values between cells, but you can only program individual cells.
Is there anyway to change the scaling on the AEM so it has finer resolution at low rpm and low loads? I would think this would be desireable since I've seen this sort of scaling applied to a few tables in my ecu. It seems to work well. |
