You should be safe with the map in it if you are just driving it easy.

I meant for the maps, of course you have to change the injector settings and you can make tweaks if needed to get it to idle better.

Ok well i guess theres something wrong because when its cold it runs fine but when it wams up it runs really rough. Another question would a street port make it run at higher temps 100 - 105 c

Do you have a wideband? AFR's can be different cold vs hot. No a street port should not make it run at higher temps.

Ya that's too rich for idle and light throttle driving. You should learn how to tune it yourself if you don't know how, it needs leaned out some, done by lowering the numbers in the inj map or base map, small amounts at a time and see how it goes.

Took the car out for a drive it was driving fine on idle and light throttle then it gets past 80 c and it starts running rough and leans out to 14 even when the car is parked and i rev it it leans out at 3k wont go higher

What are the water temp table settings for 50 and 80 degrees c.

rx7vargas

iTrader: (3)

50 is 1.07 1.01 80 is 1.00 1.00

Has it been tuned before or is it all default settings? I don't know if there could be something else wrong with the car. email me your .dat file and I'll take a look at it (you may have to put it in a zip folder and attach it to the email), tomtruxell at gmail dot com

ok ill send it tomorrow and i did notice on the sensor check that the fuel temp is reading 4.5v and is highlighted

and i did a reset on the pfc never been tuned

tom94RX-7

That shouldn't matter, that sensor gets removed/unplugged. And if it did make a difference it's only a 2% adjustment in the settings which isn't enough to make a big difference. Did you do a reset and then changed the fuel injector settings since you have 1200cc secondarys? Even if you didn't I think it should still idle not bad when hot compared to cold.

I did a reset and then changed the injector setting to 1200cc. It runs good and pulls good til it warms the higher the worse it gets so bad that that is sputters past 2k and wont go higher

I did a comparison with my fd and my brothers at the same time had them on and my car was reading 29c for air temp and his was reading 44 could that be the problem

tom94RX-7

What happens to the air temp leading as it warms up, is the air temp leading a lot different once its hot and running bad?

I keep getting this feeling that the engine is blown. water jacket seals or maybe cracked plate, I know its not the apex seals because it has RA classics and i think the shop over boosted it. I went single turbo because the efini twins broke im guessing that something went wrong when tuning it.




the shaft snapped

tom94RX-7

wow. did the car start having these problems after the that twin turbo blew? If so your engine could have injested some of those pieces when it happened, or later if some pieces were stuck in the intercooler and later sucked into the engine.

I cleaned the inter cooler and piping and I dont know because they broke when it was getting tuned. Im going to take it out and rebuild another engine that I have, i already bought a seals kit. building it again and taking it to another place to get tuned.

Took it part nothing wrong with the seals water jacket seals looked fine only problem that i saw was the oil control rings were really soft and streched out and the rotors had play on them and were showing a little copper.Also the reason the wheel was moving alot was because the person that built the engine pinched the washer bearing with the spacer when they tightened the front e shaft bolt

rx7vargas

iTrader: (3)

yep that was the problem the spacer sleeve that slides on the front of the shaft pinched the bearing

Just got done rebuilding a different engine i had Ra classics apex seals, atkins solid corner seals, atkins thermal pellet, new oil pump, race port, RA water jacket seals, ported the runners and intake manifold. Should have it in the car by this weekend

this is when it was twin turbo

BTW the problem was the harness to the coils the wires were stripped and were touching also the temp problems were from a clogged radiator
