v-tec top speed
 

my 91hatchsi with soch 1.6vtech runs fine rev good and is quick. but the car top out at 110mph @5000rpm. is this the top speed of the 95 dsol ecu i'am running or the 95 dsol engine or is it the 91si stock bolt parts. help the vtech works good car redline at around 7000rpm and car is obd1.

Re:v-tec top speed
 

The fuel cutoff for speed is 125-133MPH in stock sols. If you rev the P28 ECU up you should hit the gas cutoff at 7500 RPM. If you have the P28 and not getting this chances are the ECU is being "funny". I have ran into a few issues with non standard P28 ECU's

wouldnt the ecu out of a teg work alot better and rev higher? i know i have a ecu in my crx from a teg and it doesnt even redline ive reved it to 10g's and no cutoff... to bad the clutch slips like a mofo!! with a mini swap :)

how are you using a teg ecu on a mini-me?...with a vafc?

Re:v-tec top speed
 

it works... its a 89 teg ecu the car is a 90 crx dx.. with si - mini me swap... with a v-afc.. but we sold the vafc it was workin fine .. but my friends making a adapter to go obd1 so we dont need the vtec controller...

i'm usin an 87 teg ecu in my 87 crx, and it doesn't have a redline or fuel cutoff either lol, i missed a gear once and pinned the tach at 8k :/

Re:v-tec top speed
 

lol.. we did the si mini me swap on it and installed the $350 vafc took the thing to the track with the 1.5 tranny and a slippin clutch and ran a 17.7 in the 1/4 shh dont tell anyone.!! then reved the ---- out of it all the way home at like 10 g's if the clutch woulda held up it woulda hauled ass!!

Re:v-tec top speed
 

if you have different rims/tires on your car that are not the same diameter as the stock ones your speedometer is off. 15mph at that speed if you changed the tire size.

so it's working right, if thats the case.
