Microtech Help
Hey everyone,
Im not new to the fourms or the rx7 its been sitting for awhile and I forgot somethings about the microtech. My question I have an rx7 single turbo street port 1600cc 850cc injectors all the good stuff with a microtech lt10 and x4 setup. The car runs however it is very hard to start I think its not getting enough fuel and requires you to mash the gas in the begining. Also around 4000 rpm it backfires and continues to climb after that problably because of the wide injector gap. Im loooking for some help on how to adjust my microtech to fix these problems even just the starting issue first so I can get it to a tuner. Ill post my map below so you can view.

bump your idle maps in the 5"Hg - 2psi range, they should not be zeroed... also i would zero out the t*wat maps, you don't need additional advance for cold running.
for the staging hesitation you will need to mess with the staging % figure but that will affect all your pre stage point maps under the RPM point you have it set to stage at. |
Thanks man ill give it a shot when the weather gets nicer here

here is my map, i pretty much have the same fuel setup as you do and have never had any hard start issues. My timing numbers are exact(stabbed at 0*) and my fuel pressure is 43psi open air

yea looks as if you may be flooding it. try loading my map on there and seeing if that helps any. if not you can always type yours back in
|
okay so the car runs and starts great now that i tuned it i keep gettin a tps cal at idol and a rpmcrs when throttle is given what do them mean?
|
means your TPScal % is under the target of 0. raise the figure until the asterisk appears next to the 0% throttle figure, engine must be warm. you may get that error if the car is cold, the mazda TPS are rather crappy and even the microtech can't cure the range it soaks up from cold to warm.
|
Cars breaking up when u punch it just sittin in neutral what map needs adjustment
|
try adding 5% to the pump1amt and pump2amt
|
Cars running much better with your map however its breaking up popping anywere from 2500 to 4000 with light and steady gas but if u punch it it will go eventually. Any suggestions on what to alter is it a pump map issue? or rmpcrs/wot map issue?*
|
How is your Cas stabbed? did you stab it like factory? My map is set up for true timing( stabbed Cas at 0* rather than -5* like factory)If yours isn't then so the timing will be terribly off. Also do you have a wideband?
|
Need a new wideband any suggestions?
|
How do you reset your cas to 0 on a 3rd gen i know how to do timming
|
What does it say for your static timing on the micro? It'll be under the timing lock function

Best info for setting the timing on a rew. Really need to take it to a tuner though and have it professionally tuned. Running it the way it is now you re liable to go bang.

Sounds good thanks man i think im just gonna bring it to advanced rotary in nj by me judge ito runs it great place i heard
|
Most def man!!!
|
Nice thread helped me understand a few things.

Thanks again Rxpeed7 for posting you map and for all the help. The My friends car would not idle or rev up at all before you settings. Now it holds idle and runs good enough until we take it to Orlando to be tuned.
Ps: That is not a 13b-re motor. It's just a 13b-re UIM with an adaptor to a T2 LIM. Quick vids I took today. http://www.youtube.com/watch?v=CDRU5...ature=youtu.be http://www.youtube.com/watch?v=qMrso...ature=youtu.be |
