SLOW MOVING PROGRESS Db1 finally finished the swap...got a couple bugs leftover

[teh_mugen18]

Okay, as some of yall remember, i was having a lot of problems with my previous engine, and decided to do a swap. Now, the swap is complete, and everything seems to be straight but theres 2 little kinks leftover to iron out:

1st - the temp sending unit may or may not be out...it registers OVERHEATING less than 1 minute of the engine starting but when i go to feel/check, everything is still cool enough for me to touch bare-handed.

2nd - there is a slight/noticeable bog or lag in the throttle response under 4k rpms.


Now, i talked to a friend of mine, and he said that its more than likely my ecu that may need to be changed? or do i just possibly need a tune? Its hard to tell with this motor...

Just for additional info:
~i did a 1990 integra ls (b18a1), and swapped into it a 1994 ls engine (b18b1). transferred the original dizzy and the IM from the old engine.~

~also, one of the tps wires got torn while installing new engine. I got a new tps plug/wires and spliced it to the harness~

bump...also I noticed when I was driving it, there technically is no WOT....what I mean by that is, when I am cruising along with my foot at 25% throttle (for example), and I push the pedal to WOT, there's no response from the engine....it just continues along as normal.

did you ever fix the TPS?????

[teh_mugen18]

yeah I fixed the tps, but it only seems to work after/during certain times when the engine is on. its like my ecu is retarded or something cuz it takes a few seconds for it to realize "oh there's a tps, let's act and drive normally now!"


ooo and I'm having terrible overheating issues that I can't quite seem to straighten out....but I haven't looked through/checked all the parts yet..
