aem v1 question

[SlowWhite]

Ok I have zero knowledge about the aem v1 and my question is.

Does the v1 have any ability to adjust speedo readings?

Ex: putting larger then normal tires on the car throughing the Speedo off.

Anyway to fix it.with the aem.

Also os there anyway to fix the "rich cold start issue"?

On a 2g yes it can do all that and more. Get a wideband in the car for o2 feedback as well.

I think the gauge cluster speedo gets it's reading directly from speed sensor in the trans speedo sensor, not from the ECU.

You can adjust the startup fueling with an AEM(you have to build just about every table anyways), but cars are usually supposed to run rich during car start. The AEM has it's own problems that you need to deal with though compared to DSMLink or a reflash. Cranking fuel and warm up fueling can be adjusted in factory ECU systems also like DSMLink.

I am with Shane, thinking the AEM is driven off the speed sensor, how much larger tire are you thinking Brian?

Cars need to be richer than stoic to start and all of that can be adjusted in the AEM.

The question ia actually for a 95 supra I wad looking at.

The car has two problems. Cold start and it reads 20mph low.

The aem is for a gte motor. But the car has a built n/a motor. And I was trying to see how easy these issues would be to fix

20mph low? Something else is wrong besides the tire size. Does it have 5.13 gears in the rear or something?

[SlowWhite]

I asked the question if there was a gear size change when they installed the trd rear diff or when they built the tranny. But the owner replied he didn't request one.
However I'm pretty sure its a gearing issue in the rear diff now. Just not sure how to adjust for it or if there is a fix yet, still looking

Which trans?

From what I can tell a stock n/a diff has a different gear ratio then a trd diff.(much stronger diff)

I was hoping there was some way to compensate for this which is why I was wondering if aem had a tire size adjustments. Which might be a work around for the trd diff.
