stock speedo with sr

[boost_creep]

just wondering if the speedo is accurate after the sr swap....just got mine done..i did get a front clip and put the tach in...so thats ok...but the speedo is from the ka....and i didnt put the ka speed sensor in either???...so is it in kiolmeters?..cause i pin it at 115 in no time....but i kno im goin faster than 70...whats the deal...thanks

mine is 2mph fast. as in i'm going 68 but speedo reads 70. but the tach is off about 3-4 hundred.

hmmm...2-3 mph huh.....thats odd....thanks man...how come the tach is off though.....i put in the jdm....did u?...is the tach ahead 300 or behind?

I beleive if you put in the JDM Cluster that came with the front clip you should be fine and it should be rather accurate.

But considering you dident put the KA speed sensor i think it will be a bit off

[boost_creep]

well i didnt put the jdm cluster in....just the tach..along with the sr speed sensor...does this change things?

Thats my setup. Runs fine, reads speed right, reads tach right.

How do you know the engine speed is off? If it's a turbo timer, or any other signal, you might as well take the average of the 2 to get a closer reading.

i ran with a USDM tach for almost a year and had no problems with it reading off. Also, as long as you swap in the KA speed sensor, you should read fine. If you keep the SR speed sensor, it will be off a marginal percentage.

I know mine is accurate via an SAFC2.
