• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Some more top swap questions! Yay!



So i finally got the trims to relearn on my way home tonight so in the a.m ill take a scan and beat on it a little bit and let you guys (scotty) know how it goes!!

I found some 42.5# green top injectors for 100$ would these work good for the e85 conversion?

when/if you put in the 42.5 lb injectors, you will need to change the injector flow rate. basically what you do is find the percent difference between the stock injectors and the ones you are putting in.

42.5's should be big enough for E85 on a supercharged car.
 


Ok ya i figured id have to do some research on tuning for them. Another question if i was just going for a lower hp build can you keep stock fuel pump or at what hp point do you need to upgrade?

I am still running a stock fuel pump, but have a rewire kit in. at one point I had a 2.9 pully with full size intercooler, ported heads, XP cam and a few other things, so I would say to start with a rewire, and go from there. when the need arises, I plan on grabbing a walbro 255 from wbodystore, it's like 100 bucks and comes with everything you need. I am considering going to E85 as well, and when I do, the stock fuel pump probably wont flow enough.
 
Ok scotty just took it for a test drive so if i get on it in first or second gear i have 0kr sometime a blip of .2 or something but the downshifts are still terrible mashing it in 4th and it downshifting to 2nd results in 6-8 degrees of kr

theres a chance the trims were not learned fully when we added fuel.

being -11, id set the maf back to stock and start over,

open your bin, got to the maf folder, the top file, right click it, import stock maf file. save on exit. its back to stock where we started.
 
Well not particularly but shouldnt i be able to mash on it without so much of a kr issue or is that normal?

when it drops a gear and kicks down when you floor it, a blip is some what normal, 7º is not. a blip is less then a degree in my book. like a 0.6 kr for one cell.
 


Also i can import the stock maf table but the maf positive and maf negative tables are different too. Do i put these back to stock as well?

that i dont know, something in the tranny may not be happy.

did you ever scan for kr before the topswap? if it did that before hand, its the tranny.

or maybe the down pipe hitting the sway bar.
 
I did scan for kr before the swap. I would see a couple degrees of kr at wot all the way through the rpm range it never peaked it was just steady kr
