There is a resistor to change to modify the 6ppr to an 8ppr but for the life of me I can not remember it. I do have a 94 V8 cluster laying around I would be willing to part with before it becomes...

There is a resistor to change to modify the 6ppr to an 8ppr but for the life of me I can not remember it. I do have a 94 V8 cluster laying around I would be willing to part with before it becomes...
Thanks for the reply. I am returning from the mountains tomorrow so I will test it out in the next few days. I looked through the V2 code that is already broken down and noted and compared it to the...
I have an arduino set up to drive a waterproof servo on the dump valve I am trying to operate. I use a 5v constant with a 100ohm resistor to the arduino and the egr trigger wire off the ecu(a4 if I...
An update on the ecu controlled cutouts, they work and rather well. There was a mention about the adjustments to compensate for the egr flow, that is referenced to a partial pressure table that can...
I love the enthusiasm but to get 450RWHP you will need to spin the engine higher than a TPI will take you or go boost. I didnt see, are you planning on a different intake for the combo? I highly...
its not a HSR but an actual LT1 intake so it sits lower than the Dizzy. If I go back to a set of Gen 1 heads I will go for a stealth ram and shave the lower by about 1/4-1/2 based on clearance.
I am still running the stock gauges but have a WbO2 ran to the ecm so I can datalog with it. I use my Samsung S10 with a USB to aldl adapter for data logging with the aldldroid app. It uses the XDF...
I said the same but keep finding new options to make the 1227727 in my 1990 more interesting.
Here is an organized layout of your XDF. Both the injector size constant and voltage timing are under fuel. It looks like there is a different value for single or dual injection mode so make sure you...
So it looks like the lack of love for the 89 ecu has left you with a mess of an XDF. I'm working on reorganizing it to more managable catagories and it should help you find what you are looking for....
me too, sadly there are too many other factors that make it almost impossible to properly test.
0034 looks like the correct value for counts and if I am understanding the way the system works you should be able to put it in #38 if you are not using it. You will have to modify the multiplier in...
Check that your WbO2 counts is equal to you measured voltage as a start. The conversion from counts (0-255) is to multiply counts by 0.0195 and that should put you within a few .01 of your voltage.
With what Dave pointed out if you decide to go with a speed density setup your options are the 1227730 and 1227727 ecu. Both work the same but the 7730 is not weatherproof so it has to go inside your...
I'll compare it to mine when I get home. It may be in your warm-up table causing it to add to the base timing.
Its probably just me being overly critical. Every other time I used a widebamd I was also using megasquurt so there may have been some smoothing there. It seems to be working will at this point. I'll...
The corvette has an o2 bung about 6 inches below the manifold totalling about 12 inches from the exhaust port. So this should be close enough, my last spartan 2 did fine at this distance on my...
So far the wideband is very unstable when at idle and light loads, and the Nb seems to only have 2 outputs of 0 and .990v. I am going to try relocating the sensor ground from the O2 ground line to...
Got it fixed, didnt change the reporting scalar #37 to 01C5
I recently got my Wb 02 sensor in to do some proper WOT tuning on my Corvette. Its a 1990 with the 1227727 ecu and S_AUJP v6.4 loaded. The wideband is a spartan2 linear with a Bosch 4.9. I wired it...
No worries, had plenty of experienced like this learning my way through megasquirt. If there is any thing else I could do to help you with future improvements of they system please let me know.
Elky, not trying to sound argumentative but how may users have tested this on a corvette? There are quite a few extra modules that share the Aldl line and without a silence command they cause a...
so I got it to work. I had to carry over the entire connect and Mode 1 dump instructions to get the S_AUJP adx to work but it does and I have a few values to look at. I do think something is changed...
Have the silence code from the working ADX I just need to know can I just add it to the new ADX without wreaking havok
sorry for the delayed response, work has been hell. So I was thinking about the issue I have running S_AUJP on my corvette and I do not think it is an issue with 1227727 ecm and the modified code. I...
