Hi Im Simon

i've been noticing that using map based accel enrichment does not work that well. in really small changes in map it doesn't kick in, i even tried adjusting the values for smaller changes, but the car just studders, because it keeps changing back and forth between different values.

i was considering changing to TPS based to fix this problem. for some reason my tps currently does not work, i was thinking of changing it to a maybe a GM sensor or something

anyone try this yet?

another thing is i looked at a few people's datalog and its the same as well. using map based accel tends to lean out before a large change in map

I had a difficult time getting accel enrichment working the way I wanted. It's about 90% there but I can still make it stutter with hard accel.

I'm using a 40/60 mix of MAP and TPS. I can run 100% TPS and it's acceptable but running 100% MAP is annoying to drive. I have to touch the throttle before I start to let off the clutch.

For MAP I have 240/4; 170/3; 140/2; 100/1.2
For TPS I have 20/4; 9/3; 6/2; 3/1.2

I'm using 100% TPSdot and it works like a charm for me. I could never get MAPdot work for me like I wanted it to.

you can't blend TPS and MAPdot in MSnSE it's either one or the other.

Mine's like 80% there, it's perectly drivable, but at idle a large stab at the pedal will cause a minor stumble. it also goes quite rich when in AE. I was getting close and then i went over double in my injector sizes, so have to start again

Hi Im Simon

yea thats the probem that i am having, for some reason my TPS doesnt work with my megasquirt, it goes haywire when i plug it in.

so i'm currently using MAP only, and yeah when i slowly accelerate, AE does not pick up and add additional fuel. only when i throttle it harder it picks it up and does it. so for normal street driving it kinda blows. i guess its okay since i dont really drive it that often. weekend/track car

did anyone else have problems with the stock TPS?

thanks

I did then I found out you ONLY need the signal line, and you only need to tap (i.e. don't cut the stock ECU out of the loop) the lline. worked perfect since.

unless you have a 1.6 then you wont have a propper TPS

actually I think you mean that unless you have a 1.8 OR an automatic of any year you won't have a proper TPS i.e. years 89-93 in a manual have the fake TPS

map dot works fine if you set it up right.

Hi Im Simon

iTrader: (18)

i tried running your settings, and played around with it too, still doesnt work that well for me.

hmm....

im still confused about this TPS thing
so i need a 1.8 or auto 1.6 tps?

simon

Al Hounos

remember that i am running 450cc injectors, if you are running stockers doubling the values may help.

Hi Im Simon

iTrader: (18)

acutally, im right behind you, im running RC 440's haha

so values should be about the same

oh ok. strange that it isn't working well.

Hi Im Simon

iTrader: (18)

can someone elaborate on this TPS thing for me please

what TPS do i need.
my current one in here is a 1.6 manual TPS, but it doesnt work.

i need a 1.6 auto?
or 1.8 ....

thanks

You need a 1.8 or a 1.6 automatic TPS. The 1.6 with manual trans had a on/off switch for a TPS no linear output whatsoever thus it is USELESS for trying to control the MS.

Hi Im Simon

iTrader: (18)

so i can just put an auto 1.6 tps and put it in? or do i have to do any modifications.

simon

I have a 1.8l tps I pulled off of a throttle body if you need it.

Hi Im Simon

iTrader: (18)

if it can fit on my 1.6 liter one sure i guess. but i heard you have to modify it to fit.

how much are you looking for?
